Adding a select column...

[Paul Mason]

Hi folks,

I am aiming to create a "select" column that is unbound on datagrid whose
other columns are all data bound. The idea is to let the user select items
to be printed etc.

The problem I have arises when I want to find out which rows are selected.
The following code is a tester that puts values into a string to be
displayed, but it's representative.

Dim chk As CheckBox

Dim itm As DataGridItem

Dim str As String

For Each itm In Me.dgVialList.Items

chk = CType(itm.Cells(0).Controls(0), CheckBox)

If chk.Checked Then

str += itm.Cells(1).Text & ", "

End If

Next

The problem occurs at chk = CType(itm.Cells(0).Controls(0), CheckBox) where
it says that it cannot cast the item as a checkbox. This collection is base
0?? I have only one template control (ItemTemplate).

Any ideas?

Cheers...P

Many apologies folks...I needed to refer to itm.Cells(0).Controls(1). I'm
not sure why this should be so, but I've got it working now.

Cheers...P

Hi Paul,

Actually, the better way is:



chk = CType(itm.FindControl(checkbox_ID), CheckBox)



So you don't need to worry about it's in Controls(0) or Controls(1).
