Is there a way to use only a single command to disable all the telerik controls on a singe page in one command?

If there isn't, they can still be disabled individually, but it is a nice time saving trick if there is.

Note that we have found tutorials that describe how to individually make telerik controls read only, through programming code.  (Here is a good example: http://www.telerik.com/forums/programmatically-enabling-disabling-grid-row-editing)

Hi Kevin,

Please try the following JavaScript code snippet to disable all the Telerik controls.

JavaScript:
<script type="text/javascript">
    function pageLoad() {
        var allRadControls = $telerik.radControls;
        alert(allRadControls.length);
        for (var i = 0; i < allRadControls.length; i++) {
            allRadControls[i].set_enabled(false);
        }
    }
</script>

Thanks,
Shinu.

Sorry for the delayed response.

Is it possible to do this using only server side code (for security reasons)?

*I am speaking on behalf of Kevin and have a programming background but not a telerik background.

Hi Kevin,

In order to do it from server you need to access each control separately and you can disable it. Please have a look into the following C# code snippet which works fine at my end.

C#:
protected void Page_Load(object sender, EventArgs e)
{
    foreach (var controls in form1.Controls.OfType<Telerik.Web.UI.RadComboBox>())
    {
        //access all the combobox in the page
        controls.Enabled = false;
    }
    foreach (var controls in form1.Controls.OfType<Telerik.Web.UI.RadTextBox>())
    {
        //access all the textbox in the page
        controls.Enabled = false;
    }
}

Hope this will helps you.
Thanks,
Shinu.

Hello,

The server-side solution works 100% properly on my side:

foreach (var controls in form1.Controls.OfType<Telerik.Web.UI.RadComboBox>())
{
    //access all the combobox in the page
    controls.Enabled = false;
}
foreach (var controls in form1.Controls.OfType<Telerik.Web.UI.RadTextBox>())
{
    //access all the textbox in the page
    controls.Enabled = false;
}
foreach (var controls in form1.Controls.OfType<Telerik.Web.UI.RadButton>())
{
    //access all the textbox in the page
    controls.Enabled = false;
}

while the client-side needed some tweaking because you need to call the combobox disable() method:

disable() instead of set_enabled()

Check out this article: 
https://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/client-side-programming/objects/radcombobox-object

I hope this helps.

Best Regards,
Rumen
