DataBinding: 'System.Data.DataRowView' Does Not Contain A Property With The Name 'file_ID'.
Sep 16, 2006
HAI guys,
i am suneel.
i have a problem..please help me..
i am binding my datalist.i have set my dtakey field to the primary key of teh database.i am not displaying the primary key(file_id).but i am displaying the other fields in that table.
i have set databinder.Eval(container,dataitem."file_name").i have put one delete button in the item template...
if i want to build now...i am getting an error.....
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'file_ID'.
Here's a new one I came across that stumped me for a bit. DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'xxxx'. It appears that one of my dropdown menus was referencing the old SqlDataSource1for its data source id. I had already changed the name of the of the id to something else though. To fix it, I just updated the reference to the new name.
I m trying to UPDATE database using FormView and SqlDataSource and here is my code: <asp:SqlDataSource ID="sqlDS1" runat="server" ConnectionString="<%$ ConnectionStrings:myDB %>"UpdateCommand="UPDATE [Consultants] SET [firstName]=@FIRSTNAME,[lastName]=@LASTNAME,[skillCategoryID]=@SKILLCATID,[resourceManagerID]=@RMID,[AMgroupID]=@AMGROUPID,[SkillSet]=@SKILLSET,[statusID]=@STATUSID,[location]=@LOCATION,[comments]=@COMMENTS,[profile]=@PROFILE,[isAvailable]=@ISAVAILABLE,[dateModified]=getdate(),[focusID]=1 WHERE ([id]=@ID)"> <UpdateParameters> <asp:FormParameter FormField="txtFName" Name="FIRSTNAME" /> <asp:FormParameter FormField="txtLName" Name="LASTNAME" /> <asp:FormParameter FormField="ddlSkillCat" Name="SKILLCATID" /> <asp:FormParameter FormField="ddlRM" Name="RMID" /> <asp:FormParameter FormField="ddlAMGroup" Name="AMGROUPID" /> <asp:FormParameter FormField="txtSkillset" Name="SKILLSET" /> <asp:FormParameter FormField="ddlStatus" Name="STATUSID" Type="Int16" /> <asp:FormParameter FormField="txtLocation" Name="LOCATION" /> <asp:FormParameter FormField="txtComments" Name="COMMENTS"/> <asp:FormParameter FormField="txtProfile" Name="PROFILE" /> <asp:FormParameter FormField="cbAvailable" Name="ISAVAILABLE" /> <asp:QueryStringParameter Type="Int32" Name="ID" QueryStringField="id" /> </UpdateParameters>

Hi,Seems like a lot of people are having a similiar problem that I am having right now, but I am not able to find the solution to it. On the Page_load event, the gridview does display the data from database. When I click a button to insert the same data but different Waste_Profile_Num value, it gives me the databinding error. Component_Profile_ID is declared as an Identity and it is the primary key to the table. Anyway help???Ok, the following are code that I have: 1 <asp:SqlDataSource ID="sqlDSMaterialComposition" runat="server" ConnectionString="<%$ ConnectionStrings:HAZConnectionString %>" 2 SelectCommand="SELECT dbo.Component_Profile.Component_Profile_ID AS Component_Profile_ID, dbo.Component.Component, dbo.Component_Profile.Concentration, dbo.Component_Profile.Range, dbo.Component_Profile.Waste_Profile_Num, dbo.Component.Component_ID FROM dbo.Component INNER JOIN dbo.Component_Profile ON dbo.Component.Component_ID = dbo.Component_Profile.Component_ID WHERE (dbo.Component_Profile.Waste_Profile_Num = @Waste_Profile_Num)"> 3 <SelectParameters> 4 <asp:SessionParameter Name="Waste_Profile_Num" SessionField="Waste_Profile_Num" Type="Int32" /> 5 </SelectParameters> 6 </asp:SqlDataSource> 7 8 9 <asp:GridView ID="GridViewMaterialComposition" 10 runat="server" 11 DataKeyNames="Component_Profile_ID,Component_ID" 12 AutoGenerateColumns="False" ShowFooter="true"> 13 <Columns> 14 <asp:BoundField DataField="Component" HeaderText="Component" SortExpression="Component" FooterText="Total"/> 15 <asp:TemplateField HeaderText="Concentration" FooterStyle-Font-Bold="true"> 16 <ItemTemplate> 17 <%# SumConcentration(decimal.Parse(Eval("Concentration").ToString())).tostring("N2") %> 18 </ItemTemplate> 19 <FooterTemplate> 20 <%# GetConcentration().tostring("N2") %> 21 </FooterTemplate> 22 </asp:TemplateField> 23 <asp:BoundField DataField="Range" HeaderText="Range" SortExpression="Range" /> 24 <asp:BoundField DataField="Component_Profile_ID" HeaderText="Component_Profile_ID" ReadOnly="True" SortExpression="Component_Profile_ID" Visible="true" /> 25 <asp:BoundField DataField="Component_ID" HeaderText="Component_ID" ReadOnly="True" SortExpression="Component_ID" Visible="true"/> 26 <asp:BoundField DataField="Waste_Profile_Num" HeaderText="Waste_Profile_Num" ReadOnly="true" SortExpression="Waste_Profile_Num" Visible="true" /> 27 <asp:CommandField ShowEditButton="true" /> 28 <asp:TemplateField Visible="false"> 29 <ItemTemplate> 30 <asp:Label ID="lblComponentProfileID" runat="Server" Text='<% # Eval("Component_Profile_ID") %>'></asp:Label> 31 <asp:Label ID="lblComponentID" runat="Server" Text='<% # Eval("Component_ID") %>'></asp:Label> 32 </ItemTemplate> 33 </asp:TemplateField> 34 </Columns> 35 </asp:GridView>The following are the code-behind: 1 sqlSelect = "SELECT Range, Concentration, Component_ID FROM Component_Profile WHERE (Component_Profile.Waste_Profile_Num = " & previousWasteProfileNum & ")" 2 sqlDSMaterialComposition.SelectCommand = sqlSelect 3 Try 4 Dim dvComposition As Data.DataView = CType(sqlDSMaterialComposition.Select(DataSourceSelectArguments.Empty), Data.DataView) 5 For Each dr As Data.DataRow In dvComposition.Table.Rows 6 insertSql = "INSERT INTO Component_Profile ([Range], [Concentration], [Component_ID], [Waste_Profile_Num]) " 7 insertSql &= "VALUES (" & dr("Range").ToString.Trim & ", " & dr("Concentration").ToString.Trim & ", " & dr("Component_ID").ToString.Trim & ", " & CInt(Session("Waste_Profile_Num").ToString()) & ")" 8 sqlDSMaterialComposition.InsertCommand = insertSql 9 sqlDSMaterialComposition.Insert() 10 Next 11 Catch ex As Exception 12 13 End Try
my environment: VS2005, SQLExpress with SP1, WXP with SPs, the error msg I get is: 'System.Data.DataRowView' does not contain a property with the name 'change'. The base for all this is the 'MS Club Site' sample code downloaded from ASP.NET! After adding a new data field "change" to my DB I changed the StoredProcedure "PagedUpcommingEventList" (statement 31) and in the 'Repeater' I added statement 32 to reflect this change (see code below). When calling 'Configure Data Source' on the SQLDataSource I can read the DB (using the StoredProcedure) but I never see the new field 'change'! I certainly checked for additional StoredProcedures with the same name: "PagedUpcommingEventList" --- I definitely have only one in my project.PS: In another .aspx file using a SQLDataSource with a DataGrid; the field is showing up correctly! I spent days in the area of 'caching' without any success; thought the StoredProcedure is always called from the 'cache'! ....

I am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.
But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.
[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.
I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?
Untill recently I had a smooth running SSIS package,but suddenly it throws error syaing "OnError,,,,,,,The result of the expression
"@[User:trTextFileImpDirectory] +"SomeTextStringHere"+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ "SomeTextStringHere" " on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."
I have child SSIS package running under a parent package (through execute package task)
I have few flat file connection managers in child package for text file import , in which I am building text file path dynamically at run time by assigning an expression in connection string property of connection manager. The Expression is as follows
Where @[User:trTextFileImpDirectory] is a variable which contains path of directory containg text files.Value in this variable is assigned at runtime from parent package's variable,which in turns fetch value from a configuration file on local server.
With my current configuration this path has been configured to some other server's directory over network ( I.e my package picks text files from some other servers folder over network)
While "Some string here"+ @[User:trANTTextFileName]" part of file name string.
(DT_STR,30,1252) @[User:taging_Date_Key] Contain the date of processing ,value in this variable is also picked up at run time from parent package variable.
1) So can someone give me some insight into possible reason of failures. 2) Is it possible that problem arises if directory (from which I m picking text files) is assigned password or is there exist some problem in accessing forlders over network ? 3) Or there can be some problem in package configuration at design time( I.e where I m assigning value in variable from parent package vriables)?
hello... Probably a simple question but I have to ask...using visual basic 2005 express...
I have two tables one with last name and basic info, one with detailed info. Both set up with Primary key and Foreign key.
I have a combo box that displays the last names and then by clicking the last name, text boxes fill with the "other" data from table1, however, there are some text boxes that I would like to fill with data from the table2. Any pointers??
I’m trying to teach myself C# and trying to create a simple (so I thought) little database using Infragistic's UltraWebGrid (Althought my question is more ASPish). Every sample I run across seems to only show the very basics and doesn’t seem to go into anything more than just a simple table and displaying it in a Gird. Which is pretty easy and I can do that all day and night. Anyway, my database has three tables in a one-to-many relationship. The database is of Trucking companies and which states they service and they can service multiple states. The database is like this: Compnies: TruckerID, Company Name, Address, etc. ServiceStates: TruckerID, StateID StateNames: StateID, StateName, StateAbbreviation I would like to show the States that they service in a Hierarchical Grid. I can write the SQL to do what I want to, basically do an inner join on ServicesStates and StateNames based on the TruckerID. I can sit all day and night getting what I would like to display in the WebGrid in the query builder on the SQL server. I figured it wouldn’t be much of a stretch to be able to do that in UltraWebGrid (Or whatever floats your boat). Anyway, on to my question. :) While browsing the samples on everything, I've figured out, that I will need to use the SqlDataAdapter Class, to access the database. Then I'll need to use the SQLConnection Class, and populate a DataSet. Now while in VS I can go to WebSite -> Add New Item -> DataSet slap my tables on there and away I go (at least it seems that way). If I do that, what exactly is the difference between doing that and using the dataset class? When I do that, is that not creating the dataset? I see all the classes it created (I named mine Trucking). I see all the SQL statements in the classes. I imagine I must be missing something *REALLY* simple or this just went way over my head at by at least 40,000 ft. Thanks, marly
Hai,i'm new asp.net and vb.net i have few textboxes and few dropdownlists.i want to insert data in (.mdf )database with these textboxes and dropdown lists please anybody can tell me a sample and simple example.

Hi, I have a page created within VS 2005 which uses a detailsView with a SQLDataSource which has insert, edit and delete items allowed with it. The problem is that if I delete a record I dont want to refresh the page as I want to set a label value to say item deleted. The problem then though is to select the item to delete I have a drop down which populates the details view on index change, but if I delete the item I cannot do a databind when its complete because it just binds to the existing dataset and does not do a fresh call on the database.Is there a command I can run to refresh the dataset on click of the delete button?Thanks

I am stuck with a SSIS package and I can€™t work out. Let me know what steps are the correct in order to solve this. At first I have just a Flat File Source and then Script Component, nothing else.

Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)

The same querypreview works fine without the parameter:
SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)
Can anybody tell me why this is? And tell me a way to get the tableadapter working?
Hey all, I had a few questions about how to properly use the sqldatasource - I have a form with a single dropdownlist, databound to an sqldatasource that just has a select statement. Over the course of time, the client has requested additional dropdownlists, all of which point to different sqldatasources. After I reached 4 or 5, I noticed the page started to load incredibly slower. I played around with the caching features, and after a good while of reading up on it, finally was able to cache the page /data and notice an increase. Later, another 4 dropdownlists were added, 3 of which all take the same data. I assumed if I had 3 dropdownlists, which need the same data, I should use the same sqldatasource. What do you think? My page is behaving unaccepteably slow again. As a test, I created a new page, and bound it in the same fashion. I slowly added more dropdownlists /sqldatasources, and found it lags a bit on the initial load time (maybe 10-12 seconds of processing time before the page loads). The tables it is pulling data from do not have a primary key, and i'm doing select statements that return roughly 100-200 rows of data (per dropdownlist on average). I'm only selecting 1 column name (no select * here) I'm just curious if anyone has experienced similar issues, and also if there is anything I should do as a best practice while working with the sqldatasource. I've used hundreds of these on forms, and never experienced a problem. I only started noticing this on pages that have multiple. Also, when using multiple dropdowns that need the same data (I know that sounds goofy - why have 3 dropdownlists with the same data) should I use 3 individual datasources? Thanks for your help in advance, Mike
We are tired of null values coming out of from the database and we are directly coding behind UI decleratively. We set up a null value coding standarts but I wonder what are the disadvantages to our approach DataType The default value we send ALLOW NULL int,bit,decimal 0 NOnvarchar(string) " "(one space) NOdatetime YESbinary YES *in datetime we do not allow nulls in places such as _CREATEDATE and _LASTMODIFYDATE fields. What are other approaches for null besides writing your own layer to handle it ?
Hello, I would like to databind a textbox (the Text property) and I have try the following syntax: Text='<%# Bind("au_fname") %>' but there's no Datasource property for this control. I have defined a SqlDatasource object but can I link it to my Textbox. I have looked at the properties of the control: there's a Expressions section in which I can configure a connection string but thar's all. When I run the page I have no error but the textbox field is empty. Thanks for your help.
Does anybody know a good way to get a (near) live view of a sqlce database that doesn't involve ResultSets? I tried to use a resultset with the Sensitive option set, but it doesn't like the joins that I have to do in order to have the data make sense to the user.
If I add a new row and try to move there using the code below, nothing happens (neither movement to a new position nor error message), unless I remove the radio button bindings. (The same thing occurs if I attempt to move to any record that has a null value in the database field for a radio button).
myLastRow = dsData.Tables["Results"].NewRow();
dsData.Tables["Results"].Rows.Add(myLastRow);
I attempt to move by changing the value of the position property of the BindingContext object.
How can I retain the radio button bindings and still be able to add and move to a new row?
Currently, I have a WinCE application which uses the System.Data from NetCF and System.Data.SqlserverCE from MSSQL Server 2005 Mobile Edition. Now, I'm trying to use the System.Data.Sqlclient but I can't seem to find it in my System.Data. I notice that there are different version which is one from NetCF and one from the MS.Net framework itself.
Here's my question: Is it possible for me to use both System.Data? or should I only choose one. This is for my attempt to connect also from an SQLServer and connect to the local SQLServerCE as well.
