RadTextBox width calculation bug in Q2 '13 release that affects IE8<=

[Mike]

Hello,

FYI - We recently downloaded the latest Q2 '13 Telerik update and noticed a problem with RadTextboxes and versions of IE before IE9 (and using IE compat mode in IE9 and 10). Basically, the width calculation of the textboxes were off if you used % width on the mark up (e.g <telerik:RadTextBox ID="MyTextBox" Width="100%" runat=server">.

I traced it to be an issue with the internal _reducePixelWidthByPaddings() function. What was happening is that this function was being called multiple times (I think 5) as part of the load/repaint() process. As a result, the width of the text box was getting smaller and smaller each time. To fix, I put the following client-side code in:

if (typeof (Telerik) != "undefined" && typeof (Telerik.Web.UI.RadInputControl) != "undefined")
{
Telerik.Web.UI.RadInputControl.prototype._origReducePixelWidthByPaddings = Telerik.Web.UI.RadInputControl.prototype._reducePixelWidthByPaddings;
Telerik.Web.UI.RadInputControl.prototype._reducePixelWidthByPaddings = function ()
{
if (!this._reducedPixelWidthFlag)
this._origReducePixelWidthByPaddings();
}
}

Reporting this in hopes that a proper fix makes it into a future release.

Thanks,

Hi Mike,

I tried the described scenario in Compatibility Mode and IE 7, but on my side the method is called only once.
Could you please elaborate a bit more on this matter, which version of controls you are using and possible send us the code you are using?

Looking forward to your reply.

Galin,

The build/date # of the Telerik release I'm using is 2013.2.717.40. The file date is 7/16/13.

I can't easily provide a code snippet because our usage of RadTextboxes are a bit involved. Here is the scenario, however:

- RadGrid with a GridBoundColumns that use a FilterTemplate. These filter templates then create a RadTextBox control programatically server-side that set width = 100% (such that the grid filter takes up the full width of the column

- Client side, on page load, we are sizing the grid - perhaps this is the reason why the RadTextBox repaint() function gets called a few times, which subsequently causes _reducePixelWidthByPaddings() to be called a few times via the window.setTimeout() in the repaint() function. Because _reducePixelWidthByPaddings is called via a timeout, the bool check doesn't really work as its coded in the Telerik script in this release. That's why I had to code the work-around below - to do the bool check once _reducePixelWidthByPaddings() is called and before executing any of its original code.
