hi
I have a datagrid with 4 columns. 1st col shows the client code, 2nd col
shows the client name, 3rd col shows his address and the 4th is a template
col in which I have a delete button (in fact it is an imagebutton) in the
header section and checkboxes in the item section. The idea is to select 1
or more clients and then delete. Then I added a delete confirmation
message
to the button as follows:

In the ItemCreated event of the datagrid:
If e.Item.ItemType = ListItemType.Header Then
Dim DelButton As ImageButton = CType(e.Item.FindControl("ImgDel"),
ImageButton)
DelButton.Attributes.Add("onclick", "return confirm('Are you sure you
want
to delete the selected item(s)?');")
endif

In HTML Source of the .aspx:
asp:TemplateColumn> <HeaderTemplate
asp:ImageButton id="ImgDel" onClick="Delete_Items" runat="server"
CausesValidation="False" ImageUrl="Images/del.gif"
/asp:ImageButton> </HeaderTemplate


The sub Delete_Items:
Protected Sub Delete_Items(ByVal sender As Object, ByVal e As
System.Web.UI.ImageClickEventArgs)
Dim oItem As DataGridItem
Dim sKeys As New ArrayList

For Each oItem In DataGrid1.Items
If CType(oItem.FindControl("chkDel"), CheckBox).Checked Then
sKeys.Add(DataGrid1.DataKeys(oItem.ItemIndex))
End If
Next

If sKeys.Count <> 0 Then
DeleteClient(sKeys) 'This sub does the actual deletion
End If
End Sub

This technique works. The problem is that if I click the Delete button
even
if I've not checked any of the checkboxes, it asks me for the delete
confirmation. Do u think there's a way to skip this if no items are
checked?

thanks Vidar, it worked out.
