DataGrid Delete Problem

[thebison]

Hi all,

I hope someone can help with this relatively simple problem.
I am building a timesheet application using ASP.NET C# with Visual
Studio 2003.As it is only a protoype application, my database has been
made in MSDE.

I have a DataGrid, and have inserted a delete link button into it
through Property Builder. My Delete method works fine, however I would
like to insert a JScript popup to confirm, as otherwise users can just
delete from the database. With my normal buttons, such as a 'submit'
button on a form, I can just use the following code:

btnSubmit.Attributes.Add("onclick","javascript:if( confirm('Create new
Department - are you sure?')== false) return false;");

However with the DataGrid, the Delete link is created through the
DataGrid, and I do not know how to assign JavaScript to it. I'm sure
someone else must've had this problem before, as no-one wants users to
be able to just delete records so freely! :-)

I have already tried following this guide, but can't get it to work..

Any suggestions on how anyone has achieved this would be much
appreciated!

You can add that attribute by implementing the ItemCreated Event of the
datagrid.
Here is some sample VB.NET code. I am pretty sure you can easily rewrite
this to C#

Public Sub yourdatagrid_ItemCreated(ByVal sender As Object, e as
DataGridEventArgs) Handles yourdatagrid.ItemCreated

If (e.Item.ItemType = ListItemType.Item Or e.ItemType =
ListItemType.AlternatingItem)
Dim btn As Button = Nothing
btn = CType(e.Item.Cells(cell_index).Controls(0), Button)

btn.Attributes.Add("onclick","javascript:if(confir m('Create new
Department - are you sure?')== false) return false;")
End If

If (e.Item.ItemType = ListItemType.EditItem)
Dim btn As Button = Nothing
btn = CType(e.Item.Cells(cell_index).Controls(0), Button)

btn.Attributes.Add("onclick","javascript:if(confir m('Create new
Department - are you sure?')== false) return false;")
End If

End Sub

You have to do this both for the Item/AlternatingItem and EditItem because
when you are in edit mode the cell index will be different.

Hope this helps.
