You can use the following line of Code in your Generic handler to check if the User is Authenticated:

if (HttpContext.Current.User.Identity.IsAuthenticated)
{
//Do what you need to do for authenticated users
}

prevent repeat animation (animationextender)

Hey guys. I have a textbox which will expand when I click it. However, once expanded it's still obviously active and it will replay the animation when I click it again. How can I make the textbox expand (like the example below) when clicked, but then disable further animations of it? I obviously cant disable the textbox. I was thinking a conditionanimation would work but Im not that great with javascript.

<ajaxToolkit:AnimationExtender id="Ani" runat="server" TargetControlID="TextBox1"> <Animations> <OnClick> <Resize width="400px" duration="0.3" fps="10" /> </OnClick> </Animations></ajaxToolkit:AnimationExtender><asp:TextBox ID="TextBox1" Width="200px" TextMode="MultiLine" Rows="6" runat="server" />

Thanks /J

Hi,

Yeah , a conditional animation would be the way to go about this .

Try this Mark-Up ..

<
scriptlanguage="javascript">var expandCount = 1;var expandMaxCount = 1;
 
function ShouldIExpand()
{
var shouldExpand =false;
 
if ( expandCount <= expandMaxCount )
shouldExpand =
true;
expandCount++;
return shouldExpand ;
}
</script>

 <OnClick>
 
<ConditionConditionScript="ShouldIExpand()">
 <Resize width="400px" duration="0.3" fps="10" /></Condition> </OnClick> 
Hope this helps.

problem in implement ajax component

hi guys,

i m shaikhu. i try to implement ajax components . i start from ajax drag panel , i make it and it's working but when i drag and place panel in my page it go again it' default position not stay anywhere in my page .

Hi,

the DragPanel uses the BODY area as the drop zone. This area is determined by the layout of the page, but you can enlarge it using CSS:

body { height:600px;}

problem in returning DataTable

Hello Guys,

i am calling a ajax call to page method which returns DataTable. but i got following error

"The server method 'GetInfo" failed with the following error: System.InvalidOperationException-- A circular reference was detected while serializing an object of type 'System.Reflection.Module' "

does ajax support serializing datatable?

Thanks,

Hi,kalvagadda

The Latest version of Ajax Does not have the support of DataTable and DataSet.
