[Solved] intercept push of a button

[Fabio Craba]

I added a GridButtonColumn at runtime
        RadGrid1.Columns.Clear()
        Dim objGC_Command As New Telerik.Web.UI.GridButtonColumn
        objGC_Command.ButtonType = Telerik.Web.UI.GridButtonColumnType.PushButton
        objGC_Command.CommandName = "Select"
        objGC_Command.UniqueName = "Select"
        objGC_Command.Text = "..."
        RadGrid1.Columns.Add(objGC_Command)

I handled the event triggered by pressing the button 
        Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs)
                If e.CommandName = "Select" Then
                        ...

                End If
        End Sub

The problem is that this event is not fired when I press the button because then HTML generated is

        <input type="submit" name="ctl00$CPHMain$RadGrid1$ctl00$ctl04$ctl00" value="..." />

why?

Thanks for your attention and sorry for my English

Hi,

When you add a dynamic column to a declaratively created grid ,you need to add the columns first to the control collection and then set the property.This is important because no ViewState is managed for the object before it has been added to the corresponding collection.

Hope this helps. Do let me know if this was useful

Thanks,

I tried as suggested but still does not work, when I press the button not generated the event  "RadGrid1_ItemCommand" but is reload the page.
I set
<% @ Page enableEventValidation = "false"
and
RadGrid1.EnableViewState = "true"

What else can I do?

Hi,

Please  make sure that  you are using the AdvancedDataBinding Technique to bind your grid i.e. either using NeedDataSource or DataSource  control.
