DropDownList within GridView - update row with OnSelectedIndexChanged

I have a list of items in a GridView, with one column I'd like editable through a DropDownList.

I do not wish to put the GridView into 'edit' mode or have any 'confirm/update/save' buttons.. I just want autopostback on the DDL, and an OnSelectedIndexChangedevent to update the row.

Problem is, from my OnSelectedIndexChangedevent within the DDL, although I can see the new value to save, I can't discover the row to update from the GridView.

Can anyone see how I can achieve what I wish? Other than perhaps storing the row id within the DDL? Maybe turn it around so the GridView's events are called?

I guess this kind of questions comes from starting with ms-access :)

Cheers!

I use this, and it works well.

Protected Sub DropDownList1_SelectedIndexChanged(sender As Object, e As System.EventArgs)
    Dim TheRowIndex As Integer = sender.Parent.Parent.RowIndex
    Gridview1.UpdateRow(TheRowIndex, False)
    Gridview1.DataBind()
End Sub

You can also use this same code for CheckBox etc.

Cheers

Typically, you'd rebind the GridView with the data again to do this. You could also try looping up to the GridViewRow by accessing the DropDownList's Parent property; if you do enough parent references (ddl.Parent.Parent), eventually, one of those parent references is the GridViewRow.

HTH.
