Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put a
watch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried to
bypass the DataView thing (just as a test), but I get an object reference is null error.
The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All this
without me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked down
the temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even tried
rebooting, and nothing seems to make it work again.
My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.
My compiler says that the line in bold below is illegal. The error msg I'm getting is: No overload for method 'select' takes '0' arguments. How can I correct this error and execute a SELECT? protected void Button1_Click(object sender, EventArgs e) { SqlDataSource2.Select (); } protected void SqlDataSource2_Selected(object sender, SqlDataSourceStatusEventArgs e) {string strReadyFirstName = e.Command.Parameters["@FirstName"].Value.ToString();string strReadyLastName = e.Command.Parameters["@LastName"].Value.ToString(); } <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [User_ID], [User_Name], [FirstName], [LastName], [Company_Name], [Department_Name] FROM [CompanyDepartment] WHERE ([User_Name] = @User_Name)" OnSelected="SqlDataSource2_Selected"> <selectparameters> <asp:sessionparameter DefaultValue="TheirUserName" Name="User_Name" SessionField="TheirUserName" Type="String" /> </selectparameters> </asp:SqlDataSource>
Hi, I have a sqldatasource which returns the result I want, but I need to assign it to a label or text box. Is there an easy way of doing this? I attempted it using this code: PropertyFriendIDLabel.Text = PropUserIdSqlDataSource Thanks
Hello, I am using SessionParameters within a sqldatasource control, which is the datasource for a formview control. The Session["PoolID"] has a value which is '0000009485'.<InsertParameters><asp:SessionParameter SessionField="PoolID" Name="pool_id" Size="10" Type="String" ConvertEmptyStringToNull="true" /> </InsertParameters>But when I click 'Save' I get the message 'Cannot insert the value null into column 'pool_id'. Column does not allow nulls. Insert fails'.Do i need to specify something like DefaultValue = <%Session["PoolID"] %>?Thank you in advance for your help.RajanP.S. How can I avoid double line spacing while writing a post? Thanks.
I have the following problem: in a data flow, if inserting new records, there are columns that take some default values. These default values are kept in a table in case the user wants to change them some day. Def. values could not be assigned at a table level because there's another dataflow that populates the same table, but the rules for the default values are different.
Since I want to extract these values only if there is at least one new row, I'm not fond of the idea to use Execute SQL Task (to save the default values in a variable) before the actual Data Flow. What are my options in getting these values in a Data Flow right before inserting? Thank you for the help.
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3)) RETURNS nvarchar(1000) WITH RETURNS NULL ON NULL INPUT AS EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?
Group,Is there a way to assign nullability on a column when using a select into?I've tried some of the usual things like coalsce, isnull, and cast. Sincethe new table gets definition from the source table or can be somewhatadjusted with cast is there a way to cast a not null? In the example belowhow can I select into causing tableone_new..col2 to be not null. Wetypically must use an alter statement after the select into but this seemsinefficient.Thanks,Raycreate table tableone (col1 int not null,col2 int )goinsert tableone values (1, 1)insert tableone values (2, 2)insert tableone values (3, 3)goselectcol1,col2into tableone_newfrom tableonegoexec sp_help tableone_newgodrop table tableonegodrop table tableone_newgo
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
I think I'm just braindead or simply thick...since this shouldn't be that hard, but I'm stumped right now.
So, I'm trying to retrieve from a table, with a sql stored procedure with the sql like "select height, width, depth from products where id=@idinput"
OK, so this part is easy, but if I wanted to say, return this to my code and assign height to a variable Ht, width to Wd and depth to Dp, how could I do that?
I'm new to ASP and ASP.NET so I used the Wizards in Visual Web Deverlopment Express 2005 to build the following code:<asp:DetailsView ID="DetailsView" runat="server" DataSourceID="TracksDataSource" Height="50px" Width="125px" AutoGenerateEditButton="True" AutoGenerateRows="False"> <Fields> <asp:BoundField DataField="pk_trackID" HeaderText="pk_trackID" ReadOnly="True" SortExpression="pk_trackID" /> <asp:BoundField DataField="trackName" HeaderText="trackName" SortExpression="trackName" /> <asp:BoundField DataField="trackPath" HeaderText="trackPath" SortExpression="trackPath" /> <asp:BoundField DataField="lyrics" HeaderText="lyrics" SortExpression="lyrics" /> </Fields> </asp:DetailsView>
<asp:SqlDataSource ID="TracksDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:connectionString %>" SelectCommand="SELECT * FROM [Tracks] WHERE ([pk_trackID] = @pk_trackID)" UpdateCommand="UPDATE [Tracks] SET [trackName] = @trackName, [trackPath] = @trackPath, [lyrics] = @lyrics WHERE [pk_trackID] = @pk_trackID" > <UpdateParameters> <asp:Parameter Name="trackName" Type="String" /> <asp:Parameter Name="trackPath" Type="String" /> <asp:Parameter Name="lyrics" Type="String" /> <asp:Parameter Name="pk_trackID" Type="String" /> </UpdateParameters> <SelectParameters> <asp:ControlParameter ControlID="TracksListBox" Name="pk_trackID" PropertyName="SelectedValue" Type="String" /> </SelectParameters> </asp:SqlDataSource> However, when I click Edit, change something, and then Update it doesn't update the database. However, if I remove the DataField bindings and use the AutoGenerateRows feature it works fine.
I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast. And then firing off the update command that contains that parameter from a button. But it's not changing my data on my server when I do so. I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes. All this works fine, just not sp that should update my data when I hit the submit button. It's supposed to update one of my tables to whatever the selected value is from my drop down list. But it doesn't even change anything. It just refreshes the page and goes back to the original value for my drop down list. Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc. It just won't change the data from the page when I try to.

My total test page is shown below. I monitor the connections by SP_WHO2. Without the second call, connection pooling seems to be working, ie I refresh my browser repeately but the number of connections as seen from SP_WHO2 does not increase. However, if I have the second call, every time I refresh the page at the browser, the number of connections increases by one. This is obviously not acceptable in a real world application. I tried both Integrated Authentication (with no impersonation) and using a hardcoded service account. Both have the exact same results. In fact this test is not about multi-user yet, it is the same single user just refreshing the same page. May I know what have I done wrong? All the documentation from Microsoft says close the connection after using it. In the case of SqlDataSource how do I close the connection? Thanks <%@ Page Language="C#" %>

I have a sproce that accepts null for one of its parameters I can execute the sproce and enter null and it works fine, it returns all rows.

I am using a SQLDataSource with Stored Procedures. The Select, Insert and Update all work well. However I cannot get the delete to work. My stored procedures are tested and verified and the parameter names are the same as the source columns. When I try to run the delete an error that the stored procedure expects the parameter @locationStationId, however this value passes properly for the Update command?!? I tried to change the parameter to original_locationStationID to pass the original value, however this result in Null being passed for the parameter. I cannot understand why this works for Update and passes the location ID, but will not work for DELETE. Can anyone shed any light onto the matter?

How to pass a null to SelectParameters in SqlDataSource? The type of "CreateDate" is DateTime, the following code can be run correctly! SqlDataSource1.SelectParameters["CreateDate"].ConvertEmptyStringToNull = true;SqlDataSource1.SelectParameters["CreateDate"].DefaultValue = "2006-11-12"; now I hope to pass null value to the Parameter "CreateDate", but the following 3 section codes don't work! SqlDataSource1.SelectParameters["CreateDate"].ConvertEmptyStringToNull = true;SqlDataSource1.SelectParameters["CreateDate"].DefaultValue = string.Empty; or SqlDataSource1.SelectParameters["CreateDate"].ConvertEmptyStringToNull = true;SqlDataSource1.SelectParameters["CreateDate"].DefaultValue =null; or SqlDataSource1.SelectParameters["CreateDate"].ConvertEmptyStringToNull = true;SqlDataSource1.SelectParameters["CreateDate"].DefaultValue = "";
Hi -- I'm starting an ASP.NET 2.0 application which contains a page with a checkbox and gridview control on it. In its default state the gridview displays all the records from a table pulled from a SQL Server database (via a SqlDataSource object). When the user checks the checkbox, I want the gridview to display only the records where one of the columns is not null. But I've been unable to construct the WHERE clause of the SQLDataSource object correctly. I see that I can hard-code the SqlDataSource object so that the column to be filtered is always NULL or always NOT NULL. But I want this filtering to be more dynamic such that the decision to show all or non-null records happens at run-time. Should I be using two SqlDataSource objects -- one for the NOT NULL condition and one for the "all records" condition? Then when the user checks the checkbox, the gridview would be configured to point to the appropriate SqlDataSource object. (???) Seems like a bit of overhead with that approach. I'm hoping there's a more elegant way to get this done. Please let me know if you need more information. Thanks in advance. Bill
I'm developing a web app using VS2005. I have a webpage with panel containing a gridview populated by a SQLdatasource. The SQLdatasource in turn is populated by a stored procedure that can take up to 5 parameters. The user types in up to 5 separate words (searchterms) in a text box which are then parsed and passed to the stored proc in the datasource which performs a fulltext search. The gridview then becomes visible. My problem is that unless the user types in 5 searchterms (no less), the gridview returns zero rows. 5 searchterms returns the proper results. Somehow, I need to be able to pass in null or empty values for unneeded parameters. I've tested the stored procedure in Query Analyzer and from within the SQLdatasource configuration (using Test Query) using 0 up to 5 parameters and it works fine, so that's not my problem. Here's the code that runs after the user types in their search term(s) and presses a button:Public Sub FTSearch_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles btnFullText.Command Dim x As Integer pnlFullText.Visible = Falsefiltertext = Replace(txtSearchTxt.Text, "'", "''") If Not filtertext Is Nothing Then filtertext = filtertext.Trim Else Return End IfDim arrayString() As String = filtertext.Split(" ") Dim length As Integer = arrayString.LengthFor x = 0 To (length - 1) If Not arrayString(x) Is Nothing ThenSelect Case x Case 0 : lblFTParm1.Text = arrayString(0)Case 1 : lblFTParm2.Text = arrayString(1) Case 2 : lblFTParm3.Text = arrayString(2)Case 3 : lblFTParm4.Text = arrayString(3) Case 4 : lblFTParm5.Text = arrayString(4) End Select End If Next pnlFullText.Visible = "True" End Sub Any ideas? Thanks in advance.
I am attempting to create search parameters for a gridview control and I am experiencing a small issue. When I get to a date parameter I am unable to display null values. I setup a sqldatasource and created the parameters below to handle the selections for minimum date required and the maximum date required for the date columns in the database. The problem is I do not know how to display null dates. Is there a way to incorporate something into the search page to show null dataes?

I currently have a stored procedure that looks something like this SELECT * FROM tblQuestions WHERE Title LIKE ISNULL('%'+@Name+'%', Title)I have a form that supplies this value. This statement should make it so that if a NULL value is passed in, then it will return all the rows, if some text is specified, then it will not. On my SQLDataSource on the page where the parameter is supplied I have set ConvertEmptyStringsToNull to True, but when I say in my code,SqlDataSource1.SelectParameters.Add("@Name", TextBox1.Text);It won't give me back any of the rows, I know that the stored procedure works fine because I can get it to work by a basic query and other testing on it, so somewhere in my form, the NULL value isn't being passed, I belive that it is passing an empty string and I don't know why. Thank you in advance /jcarver
Hello, everyone! I have some fields that must have data entered into them(i.e they shd not be left blank) & since the data has to be different almost everywhere I cannot set a default also. However I have defined these columns as NOT NULL, but still when data is entered they accept null values. WHY? Please help! Thanks in advance! Adie
I'm building a stored procedure to edit a row in my database but first I'm wanting to check for null values in the parameters and set them to their respective value in the row I'm attempting to edit.
I have a problem with a SQL that check if a date column IS NULL. On one server the check work ok but on another (the same data is on both - restored copy) the check does not find any NULL values. If check where datecolumn =convert(datetime,'9999-12-31 23:59:59.000',121) I get the same result as when checking for NULL in the other.
Is there any parameter set somewhere that tell the server to return a value even if NULL is stored in the database?

Hi,I have an updatable DataGrid linked to a SQLDataSource in a web site developed using VS2005. Update works fine unless a value in the existing row is Null. Only one column in the database allows nulls.Putting a debug stop in the SqlDataSource1_Updating event, I checked the parameter value in the Immediate window and got the following result:?e.Command.Parameters(16){System.Data.SqlClient.SqlParameter}System.Data.SqlClient.SqlParameter: {System.Data.SqlClient.SqlParameter}DbType: Int32 {11}Direction: Input {1}IsNullable: FalseParameterName: "@original_FiresolveJobNo"Size: 0SourceColumn: ""SourceColumnNullMapping: FalseSourceVersion: Current {512}Value: NothingIs there a property I can set to generate a suitable Null check clause for the Update statement?Many Thanks,Keith.

When I: GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex) But nReturnCode is ALWAYS NULL... I even did a stored procedure that just: ALTER PROCEDURE [dbo].[sp_nDeletebyId] @nReturnCode bigint output, @nReturnId bigint output AS SET @nReturnCode = 0 SET @nReturnId = 0 And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock. Has anyone seen this before? The above sample stored proc did return 0 when executed one the server... and, BTW, the row is deleted!
I have an Execute SQL Task that executes "select count(*) as Row_Count from xyztable" from an Oracle Server. I'm trying to assign the result to a variable.

Which data type should I use for the variable, RowCount? I've tried Int16, Int32, Int64.
Hi,I have a query like this :SELECTx1,x2,( SELECT ... FROM ... WHERE ...UNIONSELECT ... FROM ... WHERE ...) as x3FROM ...WHERE ...The problem is that I don't want to return the results where x3 isNULL.Writing :SELECTx1,x2,( SELECT ... FROM ... WHERE ...UNIONSELECT ... FROM ... WHERE ...) as x3FROM ...WHERE ... AND x3 IS NOT NULLdoesn't work.The only solution I found is to write :SELECT * FROM((SELECTx1,x2,( SELECT ... FROM ... WHERE ...UNIONSELECT ... FROM ... WHERE ...) as x3FROM ...WHERE ...) AS R1)WHERE R1.x3 IS NOT NULLIs there a better solution? Can I use an EXISTS clause somewhere totest if x3 is null without having to have a 3rd SELECT statement?There's probably a very simple solution to do this, but I didn't findit.Thanks
Hi all,I drag sqldatasource to my form, and then adding a button there. I want when clicking the button to be able to use the sqldatasource1.select statement .
