For reproducing this you need to set: RadGrid1.DataSource = null;

Still when DataSource = new List<object>(); is set for DataSourse the RadGrid is successfully bound and does not throw errors.

I need to export data from grid without actually displaying the grid.  When I drop grid on a aspx form, set datasource with stored  procedure, one parameter linked to a drop box selected value, set some properties like export all pages, only data and then fire export to excel if I have grid visible property set to true it generates excel file with field names as headers. If I have grid visible property set to false excel file still generated but no field names added as column headers. Is it a correct behavior for the grid? I use 2013 Q3 version of Ajax .Net controls, VS2010, IE 9, Chrome.  THanks!

The latest update of Chrome browser Version 33.0.1750.117 breaks the radgrid vertical scrolling with these settings:

 <ClientSettings AllowColumnHide="True" AllowKeyboardNavigation="True">
                                    <Scrolling FrozenColumnsCount="1" UseStaticHeaders="True" AllowScroll="True" EnableVirtualScrollPaging="True" />
                                </ClientSettings>

When the grid has no paging and all the groups are collapsed its good to have a paging defined within grouping to display all the groups in the same page as well can browse through the items within the group with paging defined.

Add a new column type "AutoExpand", I have lots of grids where the number of columns changes dynamically but the width of each column is fixed, this means that the width of the grid data section changes and with only a few columns defined leave a big vertical space between the last data column and the grid right hand border.
It would be great to be able to add a AutoExpand column as the last column in the grid to fill any remaining space between the end of the last data column and the grid righthand border. This will give you a consistant look regardless of how many columns are added.

Client side data from odata works great, filter and paging with no extra coding.  Surely grouping should be done client side, requesting the amount of data it requries from the odata source.  This can make sure when groups are closing, the javascript can request more data to fill up the paging.  

Hi

When using RadGrid with popup Edit forms, it would be great if we can have a property that allows users to position the edit form just above or below the row being edited (depending on available space).

See attached file which contains three JS functions that we use to position our edit forms. We rely mainly on the '_radGridCenterPopUpToSelectedRow()' which positioned the edit form below the row being edited (or above if there is no space below) but this does not work right if the page has scrolled vertically or if we are in a child grid of an hierarchical grid.

It would be great if this could be a standard property for the Edit forms so that we do not need to keep computing the position for the pop-up edit forms.

Thanks

The grid should provide an in-built option for the filtering to be initiated only on Enter key press and not on Tab or input blur.

Bind RadGrid client-side to a WCF Data Service, using a separate GetCount method. Then filter on column typing the value 12345 in the filter textbox. The result is that the value is not passed correctly to the web service.

I am new to telerik controls.
My requirement is i should display "n" number of items based on values available in a xmldocument which is generated at runtime.
is it possible to add the columns at aspx itself and bind it or it can be done only through dynamically creating datasource and binding it?
Also i should show some images and checkboxx for selection based on some conditions
