How to reproduce: Setup a RadGrid and configure the render mode to be Lightweight. Add group by expression with one select and one group field. Export to XLSX.

Current behavior: Html code is rendered in the Excel cell

Correct behavior: No Html code should be visible

The issue appears in Classic render mode and is due to the use of an image for background which does not stretches(which is a limitation). A possible workaround is to include the following CSS:

.rgHeaderWrapper div.rgHeaderDiv{
 background:none;

}

The problem reported problem was due to specific implementation of the sample and was not caused by the RadGrid control.

The issue will not be fixed since there is a big chance to introduce a breaking change. Nevertheless, there is a simple solution that could be use. The solution is to manually remove the hidden column from the ClientState on the client.

    <script type="text/javascript">
        function test() {
            var gridID = $telerik.$(".RadGrid")[0].id;
            var clientState = document.getElementById(gridID + "_ClientState");
            var value = clientState.value;
            if (value) {
                var parsedValue = JSON.parse(value);
                parsedValue.hidedColumns = [];
                clientState.value = JSON.stringify(parsedValue);
            }
        }
    </script> 

When using the client-side resizeToFit() method of the RadGrid to automatically adjust a column's width it seems to cache the value (the computed width). If i alter on add contents to a column's header and then re-run resizeToFit() the column doesn't fit to the new contents.
I would like an option to reset the cache, maybe with an optional parameter to the resizeToFit() method.

RadGrid client events OnRowDropping and OnRowDropped do not fire if item is dropped onto itself.

If I'm to believe the Telerik agent in this forum thread... http://www.telerik.com/community/forums/reply-thread.aspx?messageId=0&threadId=750553

then presenting users WITHTEXTTHATLOOKSLIKETHIS (as is done by default in Metro Skin Grid Filter Menu) is a "design" feature. I happen to believe that menu items ought to be readable by human users and not appear like they are the result of some sort of keyboard malfunction... at least by default. If some "designer" out there feels the need to present their users with ABSURDTEXTFORMATTING, then it is they that should be required to implement some sort of hack, not the rest of us. This was a horrible design decision made by someone at Telerik, and the fact that I am required to appeal to other developers who have better things to do with their time in order to get Telerik to see the absurdity of this design and fix it is most troubling.

Add RadGrid Support per column/per grid for timezone like the RadScheduler 
Same with the  RadDateTimePicker, RadDatePicker and Calendar.

I want to use tab key for filter.
First i am entering filter text in first column then pressing tab. So i want after press tab the courser should go to next column and should allow typing. Check my demo first search with name column then press tab key the courser not going to next column and not allowing typing.

Hi Guys,

When editing a grid line on the second page on a child grid detail page the edit form selects the incorrect record to update.  It works fine if you don't use the paging on the on the child..

People keeps complaining that web grids are slower and more difficult to use than Excel.
We definitely need a radgrid control with excel-like editing.
Ideally we need the look-and-feel of the radspreadsheet, with the fixed columns of the radgrid, the events for updating a database, and maybe direct databinding to a database table.
What they want to see is Excel. Like the MS-Access UI, when they move (with keyboard) from row to row, they expect the database to get updated accordigly.
