I have a RadGrid with around 150 columns and a few hundred rows. Currently, I'm looping over them and setting their widths with the resizeColumn function. Unfortunately, it's triggering a recalculation of the layout every time I call this function, so the total page load time can be in the minutes.

Oddly, much of the time was spent on the line:
e.style.width=e.offsetWidth-d+"px";

Chrome's developer tools helpfully pointed me at Forced Reflow. Apparently, when a width is set, initially no extra work is done. When another width is requested, the previous width may have changed it, so the whole layout gets recalculated.

The feature I'd like to request is a function to set column widths in bulk (accepting anything like an array or a dictionary would be fine) that doesn't trigger this recalculation mid-function.

Update data values using drag and drop directly from the chart, something like this:

A lot of customers would have this functionality without changing the HTMLChart controls.

Twice this week, my Asp.net project would not compile because of a Telerik.Web.UI.dll link error. I run into this problem frequently, Telerik is very flakey. My last bug report was this compile problem with another Telerik file.

The solution to both compile problems is to clear the Properties/licenses.licx file. As least the second time, I knew right where to go without wasting time searching the web. A couple hours wasted on the first one on Monday.  I suppose I can expect to clear it Friday again when the compile fails on Telerik.

The Properties/licenses.licx is re-populating itself causing the compile to fail on this Telerik issue. Why have a licenses.licx if it always breaks the software? Your support says, clear the file - they know it causes endless problems.

There is no fix on my side for the this problem, Telerik must do something about the licenses.licx problem in an update.

I have these Telerik compiler warnings. The entire list is Telerik created, misleading and annoying.
