I had this working from a content page, but as soon as I move it to a master page it has an issue with the "ClientScript" saying change ClientScript to ClientScriptManager.
Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()
If (Not ClientScript.IsStartupScriptRegistered("JSScript")) Then
ScriptManager.RegisterStartupScript(Me, Me.GetType(), "@@@@MyPopUpScript", sb.ToString(), False)
Any help would be appreciated.
