Cancel Post back on OnClientSelectedIndexChanging....

Hello,

I have the following code:

    
             function OnClientSelectedIndexChanging(sender, eventArgs) 
        
                 { 
        
                   var vItem = eventArgs.get_item(); 
        
                   if (vItem.get_value() == "...") 
        
                   { 
        
                        alert('bad value'); 
        
                        return false; //cancel post back. 
        
                   } 
        
                 }

I get the alert box, but what do i need to do to cancel the post back?

TIA

Ajax and combo

I am having strange results with the combo box. For some reason it is rebindig after I bind it.

My first issue was u was trying to remove an item from the list if it was not selected. Since it was doing this word reminding, I had to remove it on the ondataload method. The next problem was that the selected value was not remaining. I set the value. I step through the code and I see it being set. Then when the page is displayed the value is no longer set. How can I track these behind the scenes processes.

Set RadGrid TabIndex=-1

I am trying to prevent a tab stop on an entire RadGrid control, but I have not been able to accomplish this. I have tried setting the TabIndex property equal to -1 and also tried surrounding the grid with a panel with a TabIndex of -1. Neither of these attempts were successful.
Can anyone provide any assistance with this issue?

Intermittent failure of captcha image to appear

Hi there

I have a consistent but intermittent (maybe 50:50) problem with the image for a radCaptcha control not being displayed, showing instead only the grey box on the occasions that the rendering fails. I know about using the HttpHandlerUrl property to explicitly provide the location of Telerik.Web.UI.axd, and the fact that the image is loaded from the Cache by default, so I am wondering if this is some issue with a cache management conflict caused by some other javascript functions I am running on page load?

Could anybody point me in a good direction about how to troubleshoot this issue, as I have run out of ideas! Is there any client-side API for radCaptcha that might allow me to examine what is going on with the captcha control as the client side script runs? Failing that, is there a recommended location for setting the HttpHandlerUrl property back at the server-side processing? I have tried the init handlers for both the page and the control itself, but nothing makes any difference to the problem.

Thanks if you can advise

SaveSettings/LoadSetting Method

this is a radFilter (not on a grid) that i would like to save & or load settings and have the filter expand and show them.
i get a method error when trying to use the :
Session["RadFilterExpressions"] = RadFilter1.SaveSettings();
LoadSettings.Enabled = true;
tells me there's no method for this. is this something that's reserved for the radGridFilters only? i've done this before on grid filters, but not the STAND ALONE RADFILTER.
and i've looked a literally every tutorial out there, so, if not doable - just lemme know and i'll walk away from this one.
thanks
