    I wrote the following code in javascript
    { var controltodisable= $find("<%= ControlToDisable.ClientID %>");

    Here, ControlToDisable is a RadTextBox.
    With the above code the textbox looks disabled but I am still able to type text in it. The text appears greyed out though.

    How can I resolve the issue?

    Also, when I disable the same textbox from clientside (JS) and codebehind (CS) there is a difference in the field display style.
    What could be the issue?

    Hi Brindavan,

    Try using the disable() method in order to disable the RadTextBox from client side.

    <telerik:RadTextBox ID="ControlToDisable" runat="server">  

    <script type="text/javascript">  
    function Disable()  
        var RadTextBox1 = $find("<%= ControlToDisable.ClientID %>");  
    RadTextBox Client Object

    Hi Princy,

    I have tested your solution and the control behaves correctly. However when I come back to the server after clicking on a button, value from the disabled textbox cannot be read.
    I solved that problem by enabling again the RadTextBox control on the OnClientClick method of the button.
    But i was wondering if there is a better way to do that.

    Hi Sonia,

    For such scenarios I suggest you set the RadTextBox to ReadOnly instead of disabling the whole control. You can try the following code to make a RadTextBox ReadOnly from client side.

    <script type="text/javascript"
    function setReadOnly() 
        var TextBox1 = $find("<%= RadTextBox1.ClientID %>"); 
        TextBox1._textBoxElement.readOnly = true

    Hope this helps,
