I have java script code to set some of the properties of ajax controls.

  • 0

I have java script code to set some of the properties of ajax controls.

the code is working OK If I put it in asp.net page but when I use content page and post the code in part of the code will not work which is changing the value of ajax control properties.

My page has textbox, checkbox, MaskedEditExtender and MaskedEditValidator.
when the user check the box the mask property and some other properties should change.

the code is working ok but not the content page.

here is my code from asp.net page:

    If you use any Extender in Content Page, the $find method’s parameter should access the Extender’s BehaviorID.

    add the BehaviorID property to the MaskedEditExtender:

           <ajaxToolkit:MaskedEditExtender ID="MaskedEditExtender6" BehaviorID="MaskedEditExtender6" runat="server" Mask="999" 
            DisplayMoney="None" MaskType="number" TargetControlID="TextBox4" ClearMaskOnLostFocus="true" 
            InputDirection="RightToLeft" AutoComplete="False"> 
        </ajaxToolkit:MaskedEditExtender>
