Hello shunman,

You could override the _applySelection function like this:

Telerik.Web.UI.RadInputControl.prototype._applySelection = function()
    {
        if (!this._isInVisibleContainer(this._textBoxElement))
        {
            return;
        }

        var control = this;

        if ((Sys.Browser.agent == Sys.Browser.Opera) || !document.selection)
        {
            this._textBoxElement.selectionStart = control._selectionStart;
            this._textBoxElement.selectionEnd = control._selectionEnd;
            return;
        }

        try
        {
            this._textBoxElement.select();

            sel = document.selection.createRange();
            sel.collapse();
            sel.moveStart('character', this._selectionStart);
            sel.collapse();
            sel.moveEnd('character', this._selectionEnd - this._selectionStart);
            sel.select();
        }
        catch (e)
        {
            var context = this;
            window.setTimeout(function ()
            {
 try
        {
                document.body.focus();

                context._textBoxElement.select();
                sel = document.selection.createRange();
                sel.collapse();
                sel.moveStart('character', context._selectionStart);
                sel.collapse();
                sel.moveEnd('character', context._selectionEnd - context._selectionStart);
                sel.select();
            }catch (e)
        {}
}, 1);
        }
    }

Hello telerik.

thank you for reply.

the code is work fine.

Is there a plan for including this code snippet to next version?

[shunman]

Hello.

I had tried some snippet to some screens.

I am facing same problem.

I  include code snippet to each screen's .js file like below.

function ddd()
{
..........
}

Telerik.Web.UI.RadInputControl.prototype._applySelection = function()

{
....................
}

a few screens doesn't not overrided function from .js file.
it still executed by Telerik.Web.UI.WebResource.axd

could you some advise me for this matter?

Hello shunman,

Use the OnLoad ClientEvent of the first RadInputControl in your form, to execute your code that overrides the _applySelection. This way you will be sure that the code is always executed and the function get's overridden before it is required.

A fix will be included in the next version of the controls, but the fix may not be exactly the same as the workaround, we will perform some additional test before and after changing the code.

All the best,
