Ajax Update panel button disable/enable

I am trying to disable a button after the request begins and then enable when the request ends. I've gotten the disable part to work but it does not enable it. What am i doing wrong? Here is my code.

Thanks.

<formid="form1"runat="server">

<ajaxToolkit:ToolkitScriptManagerrunat="server"ID="ToolkitScriptManager1"EnableScriptGlobalization="true"EnableScriptLocalization="true"></ajaxToolkit:ToolkitScriptManager>

<scripttype="text/javascript">

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(HideButton);

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(ShowButton);

function ShowButton()

{

$get("Button1").disabled ="false";

}

function HideButton()

{

$get("Button1").disabled ="true";

}

</script>

<div>

<ajax:UpdatePanelID="UpdatePanel1"runat="server">

<ContentTemplate>

<asp:ButtonID="Button1"runat="server"Text="Button"OnClick="Button1_Click"/>

<asp:LabelID="lblTest"runat="server"></asp:Label>

</ContentTemplate>

</ajax:UpdatePanel>

<ajax:UpdateProgressID="UpdateProgress1"runat="server"AssociatedUpdatePanelID="UpdatePanel1">

<ProgressTemplate>

processing.....

</ProgressTemplate>

</ajax:UpdateProgress>

</div>

</form>

Hi Azminer,

My understanding of your issue is that the button you disabled when beginRequest event is fired cannot be enabled when the partial-update finished. If I ahve misunderstood you , please feel free to let me know.

I think your problem is caused by this sentence ($get("Button1").disabled ="false") that you have assigned a string value to a bool variable. Here is my sample:

<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(HideButton);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(ShowButton);
function ShowButton(){
$get("<%=Button1.ClientID %>").disabled = false;
}
function HideButton(){
$get("<%=Button1.ClientID %>").disabled = true;
}
</script>

By the way, in your situation, you can get the same result without doing anything in endRequest event since the elements inside the UpdatePanel has been refreshed.

Best Regards,

Jonathan
