Setting UpdatePanel Trigger control ID to GridView template control

I have a linkbutton control inside a template column of a gridview control. I'm trying to use that as a trigger to update an updatepanel control on the page, however atlas can't find the control by the simple ID "linkButton1". Is there a syntax that will allow me to specify the LinkButton control inside the gridview column template?

I don't think you can setup your trigger that listens for the linkButton itself because when the grid is rendered each linkbutton on each row will be given a unique ID by .NET.  For example, if in the template definition you call the linkButton myButton, then when the page is rendered .NET will assign the button on row 1 ID=myButton_1 and on row 2 ID=myButton_2 etc. The only way to setup triggers in this case would be to create them on the fly as the page is rendered.

I would try assigning a CommandName to the linkbutton in your template column.  This should then trigger a rowCommand event when the button is clicked and you can setup your triger to listen for the rowCommand event on your gridView instead.

You could handle the GridView's RowCreated event and call ScriptManager.RegisterAsyncPostBackControl on each button. Then in the button's event handler call UpdatePanel.Update() to get it to update.

Man you're a star, been looking for that one for days! Big Smile

I am actually trying to do a full postback because my button control is actually doing a Response.BinaryWrite() to serve a file that is stored in a database table...

I little complex but it works man and it's sooo beautiful in a fully paged/sortable ajax GridView Cool

It works perfectly this is how my Row_Created event looks like :

    Protected Sub gridOffersPush_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gridOffersPush.RowCreated

        Dim cmdShowOfferDetailsDoc As ImageButton
        cmdShowOfferDetailsDoc = CType(e.Row.FindControl("cmdShowOfferDetailsDoc"), ImageButton)

        Dim objSM As ScriptManager
        objSM = Me.Page.Master.FindControl("TheScriptManager")

        If Not objSM Is Nothing And Not cmdShowOfferDetailsDoc Is Nothing Then
        End If

    End Sub
 Thanks again for the tip, you're the man Eilon!
