hi, i post this question before, but maybe not clear, so here we goes:
in my datagrid, i have a delete button to delete multiple rows(every row is got a checkbox). i need to put a confirm window before actually delete those selected items, the window is popup, however, there is a for loop for searching selected item's title (so user can see clearly what items will be deleted) is not running! i dun know why, the for loop is there! but it seems be skiped when running so i couldn't get selected item's title, anyone knows why? many thanks!

'add confirmation window on delete button
    Private Sub DataGrid1_ItemGreated(ByVal Sender As Object, ByVal e As DataGridItemEventArgs) Handles DataGrid1.ItemCreated

        Dim delIDs As String = ""
        ' this for loop is not actually running?
        For Each i As DataGridItem In DataGrid1.Items

            Dim deleteChkBxItem As CheckBox = CType(i.FindControl("DeleteThis"), CheckBox)

            If deleteChkBxItem.Checked Then
                delIDs += CType(i.FindControl("Hyperlink8"), HyperLink).Text.ToString + ","
            End If

        Next


        Select Case e.Item.ItemType
            Case ListItemType.Item, ListItemType.AlternatingItem, ListItemType.EditItem, ListItemType.Header
                Dim myDeleteButton As WebControl
                myDeleteButton = e.Item.FindControl("delConfirm")

                If myDeleteButton Is Nothing Then
                Else

                    myDeleteButton.Attributes.Add("onClick", "return confirm('Are you sure you want to delete the following News? " + delIDs + " ');")

                End If

        End Select

        chkState()
    End Sub

First: The loop is running. But since you put it in the itemcreated event, it will only run once, once for each grid item created.
Second: You would need the server side loop code to run before the client side confirm. This cannot happen since the client side code will fire first.

thanks for your reply, is there any solutions?

I guess you could gather the info, and instead of using a popup, pass it to another page. There you can ask if they want to delete or not. If so, delete as needed and redirect to some page, otherwise redirect to the previous page.

you mean to use another page as the popup window?as in winform application, a popup windows is actually another winform.


many thanks for your help!

Is this a windows app or a web app? This forum is for asp.net apps.

oh, it's web form, i was just thinking is that gonna be similar?

A pop up window in a web app is is a web page. However, like I said, you can't execute the server side code before the client side code. So, I suggested you just redirect to another web page.

thanks very much! i will try that.
