Hopefully someone can quickly help with this one, I have spent many hours on other articles and approaches and beleive it is able to be solved using the - AjaxControlToolkit.Utility.SetFocusOnLoad method, however I am having troubles correctly referencing the FindControl, below is the code
As this page is also using a Master page, I 'm not sure how to get around accessing the HTML <body> OnLoad for a client side solution, but would prefer a server side solution if there is one.
OnLoad
' try to force focus to a control which is itself, within an AJAX tab'
If Not (IsNothing(Session("ControlIDforFocus"))) Then
Try
Session("Temp") = ""
AjaxControlToolkit.Utility.SetFocusOnLoad(FindControl("ContentMain").FindControl(Session("ControlIDforFocus")))
Session("Temp") = "AJAX SetFocusOnLoad worked"
Catch ex As Exception
Session("Temp") = "AJAX default focus failed"
End Try
' track which path the try logic takes'
TempDebugLabel2.Text = Session("Temp")
End If** I now know the above code is wrong, see my later reply / correction explaining how I implimented FindControl
The Page markup
<asp:Content ID="ContentMain" ContentPlaceHolderID="MainContent" runat="server">
<asp:TabContainer ID="TestCentreTabContainer" runat="server" Width="100%"
ActiveTabIndex="3">
<asp:TabPanel runat="server" ID="DoTestTabPanel">
... other layers of markup tags being DIVs and other Panels etc
<asp:Panel ID="DoTestTab_StartTestPanel" runat="server">
..... this panels content, which is not needing to be referenced at all</asp:Panel><asp:Panel ID="DoTestTab_TakeTestPanel" runat="server">
... other layers of markup tags being DIVs etc
*** I need to be able to reference / setfocus to the below control during a postback ***<asp:TextBox ID="DoTestTab_QuestionAnswerEnteredTextBox" runat="server" Width='50px'></asp:TextBox><br /></asp:Panel></asp:TabPanel></asp:TabContainer>
</asp:Content>
