Which row in datagrid is being selected?
-
Hi, I have a datagrid with some boundcolumns and one templatecolumn. In the template column, i added a dropdownlist. Now on my page, i created a function to handle the SelectedIndexChanged event of the dropdownlist. And so far I am able to trap the event.
Protected Sub MyDropdownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim dpl as DropdownList ' How to determine which row's dropdown list did user select? nIndex = 0 dpl = CType(MyDataGrid.Items(nIndex).Cells(7).FindControl("MyDropdownList"), DropDownList) ' Do something with dpl End SubThe problem (as stated in the comment above) is how do I know which row's dropdown list the user selected? I tried to use the selectedindex of the datagrid, but it seems to store garbage values. Thanks -

DataGridItemobject containing the DropDownList, you can do as below: + You first cast the sender object to theDropDownListtype to obtain the reference to the DropDownList. + You then cast theNamingContainerproperty of the DropDownList object to theDataGridItemtype. You now have the reference to theDataGridIteminstance. -
