RadTextbox changing to ReadOnly ServerSide

[Annette]

I'm trying to change the RadTextBoxes to readonly but it's not taking the change.

((Telerik.Web.UI.RadTextBox)uiControl).ReadOnly = true;

I have this in the page load event

Annette:

I am able to set RadTextBox1.ReadOnly = true; in the Page_Load event with no issues.

Default.aspx:

        <telerik:RadTextBox ID="RadTextBox1" Runat="server" EmptyMessage="- Enter your name -"
            Label="Name:" SelectionOnFocus="CaretToEnd" Skin="Default" ToolTip="Name to which item should be
shipped." width="161px">
        </telerik:RadTextBox>

 
Default.aspx.cs:

using Telerik.Web.UI;

public partial class Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        RadTextBox1.ReadOnly = true;
    }
}

You also have the option to set the RadTextBox to read only status on the client-side using JavaScript:

Default.aspx:

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

 
Hope this helps!
