Hi Albert,

From the link provided - "http://www.telerik.com/help/aspnet-ajax/tree_clientradtreeviewobject.html'

  I tried implementing the below function in my application;

function disableTreeView()
{
   var tree = $find("<%= RadTreeView1.ClientID %>");
   if(tree.get_enabled())
   {
      tree.set_enabled(false);
   }
   else
   {
      tree.set_enabled(true);
   }
}

Query 1: I'm unable to execute code with "$find", Is it a javascript built-in function?

Query 2: Instead of "$find", I tried the following:

var ctrl='<%=rTreeView.ClientID%>';
var tree = document.getElementById(ctrl);
tree.set_enabled(true);

But the above code threw an error saying "Object does not support set_enabled method". I'm using RadTreeView.Net2.dll - version: 6.0.3.0.
Please let me know whether its supported in this version.

Regards,
Avik Basu

Hi Albert,

Even if I'm not using the latest version of radtreeview, I'm able to enable the text of the nodes of the radtree, but not being able to enable the checkboxes related to the nodes.

In the server side I'm using the code to disable as

rTreeView.Enabled=false;

In the client side I'm looping through the whole radtree and making each node enable as

tree.AllNodes[i].Enabled=true

What is the wrong with this approach, that it is not enabling completely (only on clicking on the text the checkbox is getting checked but the checkbox itself is disabled)?

What is the alternative solution to enable both the checkboxes and the nodes with the current version I'm using?

I right noe being able to get the calendars on clicking of the raddatepicker but there are a few problems which I am still facing (I am making the radDatePicker enabled=false in the server side)

1. I got the user controls so when I am using the code like:

obj16.PopupButton.onclick =

function()

{

obj16.TogglePopup();

return false;

}

it is always coming beside one control, I am not getting two calendars for eah of the two radDatePicker.

2. On clicking on any date, the selected date is not appearing in the textbox of the datepicker.

How will I able to get the control enabled from the client side.

Plese let me know ASAP because it's very urgent for me

Hello Avik,

You can enable and disable RadDatePicker totally on the client in the following way. We have two RadDatePickers and a button which toggeles the enabled/disabled state:

    
                    <table> 
        
                    <tr> 
        
                        <td> 
        
                            <telerik:RadDatePicker ID="Picker1" runat="server"> 
        
                            </telerik:RadDatePicker> 
        
                        </td> 
        
                        <td> 
        
                            <telerik:RadDatePicker ID="Picker2" runat="server"> 
        
                            </telerik:RadDatePicker> 
        
                        </td> 
        
                        <td> 
        
                            <asp:LinkButton ID="Button1" runat="server" Text="Disable" OnClientClick="return Click(this, event);"></asp:LinkButton> 
        
                        </td> 
        
                    </tr> 
        
                    </table>

And we define the javascript Click() event handler in the following way:

    
                    function Click(sender, args) 
        
                    { 
        
                        var picker1 = $find("<%= Picker1.ClientID %>"); 
        
                        var picker2 = $find("<%= Picker2.ClientID %>"); 
        
                        picker1.set_enabled(!picker1.get_enabled()); 
        
                        picker2.set_enabled(!picker2.get_enabled()); 
        
                        if(picker1.get_enabled()) 
        
                            sender.innerHTML = "Disable"; 
        
                        else 
        
                            sender.innerHTML = "Enable"; 
        
                        return false; 
        
                    }

This code toggles between the enabled/disabled states of the two RadDatePickers. When RadDatePicker is disabled, it is grayed out and inaccessible both for the input and for the calendar button.
