Hi All!

I have a CheckBox, which must enable/disable RadColorPicker on client.

<asp:CheckBox ID="CheckBoxCreateDefaultPage" runat="server" Checked="true" onclick="CheckCreateDefaultPage(this)" /> 
<telerik:RadColorPicker ID="RadColorPicker1" runat="server" ShowIcon="true" ShowEmptyColor="false" /> 

and JavaScriptFunction:

            function CheckCreateDefaultPage(sender) {  
                var state = sender.checked;  
                var colorPicker = $find("<%= RadColorPicker1.ClientID %>");  
                colorPicker.set_enabled(!state);  
            }  
 

But I dont get any changes on RadColorPicker enabling.

What I forget? Or what wrong I do?

Hello Andy,

Thank you for reportng this problem, I was able to reproduce it. We will do our best to fix it for our next release which is sheduled for next week but I cannot ensure you that we will succeed because there is very little time left and there are a lot of tasks with a higher priority set.

For the time being I suggestto use the following workaround:

 
        <script type="text/javascript">  
          function CheckCreateDefaultPage(sender)   
          {  
             
                var state = sender.checked;   
                var colorPicker = $find("<%= RadColorPicker1.ClientID %>");     
                colorPicker.set_enabled(!state);   
                ToggleEnabled()  
          }     
          function ToggleEnabled()  
          {  
             var colorPicker = $find("<%= RadColorPicker1.ClientID %>");     
             if (colorPicker._enabled)  
             {  
                colorPicker._disposeHandlers();  
                Sys.UI.DomElement.addCssClass( $get("<%= RadColorPicker1.ClientID %>"),"cpDisabled");   
                colorPicker._enabled = false;    
             }  
             else  
             {   
               colorPicker._initializeEventHandlers();  
               Sys.UI.DomElement.removeCssClass( $get("<%= RadColorPicker1.ClientID %>"),"cpDisabled");     
               colorPicker._enabled = true;  
             }       
          }  
        </script> 
 
        <asp:CheckBox ID="CheckBoxCreateDefaultPage" runat="server" Checked="true" onclick="CheckCreateDefaultPage(this)" /> 
        <telerik:RadColorPicker ID="RadColorPicker1" runat="server" ShowIcon="true" ShowEmptyColor="false" 
            Enabled="true" /> 

For your convenience I also attached my test page. I also updated your account with 500 Telerik points for your cooperation.
