hoq to fill gridview dropdownlist from another db table

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

Hello, I have a gridview control. When it goes into Edit mode, there are 3 dropdownlists in one cell that are populated by separate stored procedures during the RowDataBound event. The 1st dropdownlist's value is used as a parameter to determine what the 2nd dropdownlist is populated with. The 2nd dropdownlist's value is used as a parameter to determine what the 3rd dropdownlist is populated with. Everything works fine when the row is first put into Edit mode. While I'm in Edit mode and I change the selection in the 1st dropdownlist, how do I access the control so I can feed this new parameter to the 2nd dropdownlist? I have the first 2 dropdownlists set for AutoPostBack so that the Page_Load event is fired when the user changes a value. I know how to get access to these controls via the FindControl method when the row is being databound but how do I find the control during the Page_Load event? Thanks for any help!!!   Penny

We're trying to convert an older access app with a sql server back end (with many tables) to Sharepoint. There are entry forms, update forms, look up forms, reports, etc the 2 questions I have are: 1. How can I create a dropdownlist that gets its items from a SQL table? 2. How can I create a form that, when filled out, puts items into multiple tables? Basically, I'd like to know if any of this is possible in 2010, and does anyone have any tips on where to start?

Hi, I want to display a dropdownlist inside one cell in my gridview when the user clicks edit. The user should then be able to select an option from the dropdownlist then click update and the selected option will be stored in the cell as text. The gridview is populated using a dataset which is created according to information selected by the user. During the row editing event I remove the textbox control from the cell then add the dropdownlist which is populated from a database table. This displays fine but the dropdown list then can't be found inside the row updating event. Here is a my code: Sub GridView_RowEditing event GridView.EditIndex = e.NewEditIndex   Dim ddl As New DropDownList ddl.ID = "DropDownList1" 'Populate dropdownlist from database GridView.Rows(GridView.EditIndex).Cells(7).Controls.RemoveAt(0) GridView.Rows(GridView.EditIndex).Cells(7).Controls.Add(ddl) End Sub Sub GridView_RowUpdating event Dim row As GridViewRow Dim row2 As DataRow row = CType(GridView.Rows(e.RowIndex), GridViewRow) 'I construct the new row (row2) here and try to find the dropdownlist to get something out of it but throws a null refference exception. row2(6) = CType(row.Cells(7).FindControl("DropDownList1"), DropDownList).Items(0).Text myDataSet.Tables(0).Rows(GridView.EditIndex).Delete() '

Seems in Infopath, you can not loop a list; and you can not insert item with actions to a repeating table?
