When creating a windows forms report (rdl), multi-value parameters are rendered with a nice drop down list with check boxes...including a (Select All) item. When you run this via a report server and render the report for the web, the multi-value selection shows up nicely.
Can I create a similar web form dropdownlist so I can duplicate the functionality with an RDLC report?
Thanks in advance for taking the tiemt o read this post:
I am workingon an application in vb.net 2008 and I have 5 drop down lists on my page. I have code that worked in .net 2005 for my databind but would like to use new features in 08 to do this same thing. Here is my 05 code how would I do this same things in 08?

Not sure if this is possible, but maybe. I have a table that contains a bunch of logs. I'm doing something like SELECT * FROM LOGS. The primary key in this table is LogID. I have another table that contains error messages. Each LogID could have multiple error messages associated with it. To get the error messages. When I perform my first select query listed above, I would like one of the columns to be populated with ALL the error messages for that particular LogID (SELECT * FROM ERRORS WHERE LogID = MyLogID). Any thoughts as to how I could accomplish such a daring feat?
Hi, not exactly too sure if this can be done but I have a need to run a query which will return a list of values from 1 column. Then I need to iterate this list to produce the resultset for return. This is implemented as a stored procedure
declare @OwnerIdent varchar(7) set @OwnerIdent='A12345B'
SELECT table1.val1 FROM table1 INNER JOIN table2 ON table1. Ident = table2.Ident WHERE table2.Ident = @OwnerIdent
'Now for each result of the above I need to run the below query
SELECT Clients.Name , Clients.Address1 , Clients.BPhone, Clients.email FROM Clients INNER JOIN Growers ON Clients.ClientKey = Growers.ClientKey WHERE Growers.PIN = @newpin)
Hello:I have add a DropDownList to my GridView and binded the dropdownlist to a field from a select statement in the SQLDataSource. I have EnabledEditing for my GridView. The GridView is populated with information from the select statement. Some of the information returned from the select statement is null. The field where the dropdownlist is binded it is null in some cases and does not have a value that is in the dropdownlist so I get and error when I attempt to do an update. 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value Is there a way to get around this besides initializing all the columns in the table that are going to be binded to a dropdownlist to a value in the dropdownlist?

I'm using the GridView to display some accounting infromation. I have a project where I have a 14 character control number. I would like to have a dropdown list to select the account classification of records to be displayed. The accounting classification is the first two characters of the control number. So the dropdown list needs to show unique first two characters and the GridView will be filtered on these two characters. I have been trying to use "substring" in the ASP.NET code; not even sure you can. Any suggestions on how to accomplish this would be greatly appreciated. See code below: <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource2" DataTextField="control_num" DataValueField="control_num"> </asp:DropDownList><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:GPCRReportsConnectionString %>" SelectCommand="SELECT DISTINCT [substring(control_num,1,2)] FROM [Request]"></asp:SqlDataSource> ERROR: Invalid column name 'substring(control_num,1,2)'.

I've got the following code and it's not really what I want. With the below code I can select in a dropdownlist a value and in the other dropdownlist the correspondending value will be selected. But when I select a value the second dropdownlist won't be filled with all the data in the database. It is filled only with the correspondending value and not with the rest of the value. When someone changes his mind and want to select a value in the dropdownlist it can't be done.

Using asp.net 2.0 and visual studio 2005. The question is regarding the following ER diagram: I've made Firstname, lastname, buildingID and RoomNum all required fields. I've got a modified GridView that displays all of the table Faculty columns. It's been modified so the BuildingID and DepID are resolved to their actual field names and displayed in a DropDownList. In the dropdown list I used for inserting (a seperate DetailsView control), I manually inserted an item into the Department dropdownlist which had the text "-- Select a Department --" with a value of -1. MS SQL didn't like that -1 value so I wrote the following code to fix it: protected void dsFaculty_Inserting(object sender, SqlDataSourceCommandEventArgs e) { if (e.Command.Parameters["@DeptID"].Value.ToString() == "-1") { e.Command.Parameters["@DeptID"].Value = null; } } That means of course DeptID is null, which is ok. The problem arises is when I try to edit that row in the GridView. I get the an error 'ddlDepartment' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: valueIdeally, I'd like to make the dropdown list in the GridView show "-- None --" for the DeptID if it comes across a null value. I already tried playing around with the Command.Parameters in the dsFaculty_Selected function, but it didn't work. Ideas?
I am using Visual Studio 2005 & SQL Server. How do i implement a DDL for users to select which value to input. like i can with Access. i do not need a table i think. if not the table would have only ID & Value.?
My goal is to populate a dropdownlist with only with users that are "Techs". I am using the membership database that you ccan set up through VWD. I added this column to the aspnet_Users table: IsTech as bit datatype. I thought I had the right SQL statement but apparently not, because I get an Invalid column name 'True'.Here is my statement: <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:HRIServiceConnectionString1 %>" SelectCommand="SELECT [UserID], [FirstName]+ ' ' + [LastName] AS techid FROM [aspnet_Users] WHERE [isTech] = True ORDER BY [LastName], [FirstName]"> </asp:SqlDataSource>
I am using the createuserwizard, and have set up my own profile table which hold first name, last etc. In my CreateUserWizard, the field for Vendor is a dropdownlist that is to be populated from a list in a database. I set up the form without the createuserwizard, and everything went skippy, but when I placed it into the wizard, I now cannot access the control of the dropdownlist. I have tried doing.. Using SqlConnection As New SqlConnection(WebConfigurationManager.ConnectionStrings("Personal").ConnectionString)Dim VendorID As DropDownListVendorID = CType(CreateUserWizard1.FindControl("VendorName"), DropDownList) Dim MyReader As SqlDataReaderDim sel As String = String.Format("SELECT VendorID, Name FROM Vendors")Dim MyCommand As SqlCommandMyCommand = New SqlCommandMyCommand.CommandText = selMyCommand.CommandType = CommandType.TextMyCommand.Connection = SqlConnectionMyCommand.Connection.Open()MyReader = MyCommand.ExecuteReader(CommandBehavior.CloseConnection)But when I go to databind, it says:Object reference not set to an instance of an object. VendorID.DataSource = MyReaderLine 30: VendorID.DataValueField = "VendorID"Line 31: VendorID.DataTextField = "Name"
I have a huge problem that ive been sitting with for awhile.
I have a web page with 4 dropdownlist boxes on it
Gender: Race: Field: Location:
Now a user can search a SQL db from selecting values from these 4 dropdownlist boxes which are equal to values in the db obviously.
when they have done that and pressed submit a Gridview is populated with the people corresponding details and the user is able to view each row seperately.
Now the problem i am having is that when i havent used all 4 selections for eg
Gender: null (no value selected) Race: Black Field: Accounting Location: Los Angeles
then no information is returned from the db in the gridview. im using a sqldatasource to populate the gridview and here is the query string that i am using :
Code:
sql SELECT [title], [gender], [initials], [name], [surname], [birthdate], [postaladdress], [suburb], [city], [zipcode], [criminalrecord], [drivers], [maritalstatus], [dependants], [citizenship], [province], [contactref], [hometel], [cell], [jobtitle], [relocate], [emmigrate], [email], [worktel], [enddate], [startdate], [FIELD], [education], [company], [positionheld], [jobdescription], [contactperson], [contacttel], [startdate2], [contactperson3], [jobdescription3], [positionheld3], [company3], [enddate3], [startdate3], [contacttel3], [other] FROM [cvinformation] WHERE (([race] = CASE WHEN @race IS NOT NULL THEN @race ELSE [race] END) AND ([province] = CASE WHEN @province IS NOT NULL THEN @province ELSE [province] END) AND ([education] = CASE WHEN @education IS NOT NULL THEN @education ELSE [education] END))
what i want to do is whether the user doesnt choose any selection and leaves the choice null that ALL the information in the table of the db be shown and even if they only choose 2 values and leave the others null then it still brings back the information from the criteria chosen..
I have a listbox that lists countries....and if you choose a country, another listbox show cities in that country (fetched from a sql database)....And if you then chose a city in the second listbox, a dropdownlist will show restaurants in the city....(also fetched from a sql-database)...
Ok...I hope you understand...now to the problem....:
If you first chose a country, a city and a restaurant but then want to chose another country in the first listbox, the dropdownlist for the restaurants is still there filled with restaurants for the first country...I dont know how to "remove" the restaurants so that the dropdownlist is blank if someone switch country....
I think I need to do something in countryListbox_SelectedIndexChange....but I dont know what to write there....
I know that I can make the dropdownlist invisible by entering the following code:
When I run simple select against my view in Query Analyzer, I get result set in one sort order. The sort order differs, when I BCP the same view. Using third technique i.e. Select Into, I have observed the sort order is again different in the resulting table. My question is what is the difference in mechanisim of query analyzer, bcp, and select into. Thanks
Hey all, I've been searching for a while and haven't really found an answer for what I'm trying to do. Here it all is and someone can tell me if I'm going in the wrong direction to solve this. I have a textbox set to a parameter of "SearchString" and a DropDownList with the SelectedValue paramter of "FilterValue". The parameters work, I've tested that. So here is the problem. I am trying to use the "FilterValue" to pick the field that the "SearchString" searches with a LIKE statement (e.g. SELECT * FROM dbo.Units WHERE (@FilterValue LIKE '%'+@SearchString+'%')) This, I've found out, doesn't work. I have this setup with a DataLayer.vb in my App_Code directory handling the SQL calls, while the normal CodeBehind is in the typical "Default.vb" page. I will post code later as I don't have access to it right now, but if anyone can explain how a filter like this would work I would appreciate it! Thanks,
hello..i need your help to provide me the idea and code how to view the data from database based on search criteria from user's input?the user's may fill up textbox and choose a criteria from dropdownlist...i am so no idea how to code it since i am fairly new in asp.net

Say a record has four columns in { Emp#, firstName, secondName, thirdName, spouseName }. Now if you configure a sql datasource for a dropdownlist to return all columns, only Emp# will be displayed in the dropdownlist, the other columns wont be listed. Is there a way to list the values of all columns in the dropdownlist using the sql datasource or in ADO.net code. Thanks.
