Reference: http://www.telerik.com/forums/radgrid-column-header-and-data-item-alignment-problem

This has apparently been an issue with RadGrid for a long time, according to the above thread. I have done a significant amount of testing to isolate this bug and have attached a self-contained solution in VB.NET 4.0 (VS 2010).

I removed all the surplus RadGrid properties I could in order to simplify the debugging process on your end and included my notes in the code and on the test page. There is indeed some peculiar behavior with the control.

It should be client's decision to style his grid, we can not change the dimentions, since it will bre breaking change for the rest of the customers

It would be nice if automatic insert/update functions could require unique data.  I would love to use these features, but always have to write the insert and update routines manually to check that duplicates are not used.

Time independent filtering (EqualTo problem) is currently not supported with client-side binding in RadGrid, using a WCF with odata  binding.
When i use the filter in a date column, the filter does not return records, it is because is passing date AND TIME to the OData service. 
I have open a support ticket #932463, but Daniel says it is a new feature and not a bug.
So i request it.

Dear Team, Please add html print button as server method with radgird. So we can get the clean html page with perfect repeated headers and footer with page nos.

The virtual keyboard disappears when focus cell in RadGrid with batch editing in iOS8.3. The keyboard briefly shows up and gets hidden almost immediately when trying to edit item in batch edit mode.

1. Add row to grid.
2. Delete the exact same row.
3. Press save changes button.
- Client side error, as seen http://prntscr.com/7qf6zr

When using RadGrid GridDropDownColumn that displays referenced data from a different table allow filter to be replaced with a dropdown of available values. For example if my database has a table called Groups with and Id field and Name field; and it also contains a Members table with a GroupId field which contains the Id from the Groups table when I configure the Members GroupId Field with GridDropDownColumn with ListTextField="Name" ListValueField="Id" DataField="GroupId" as the values for the dropdown I should be able to choose FilterType="DropDownControl" to get the functionality found here http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx for City and Country columns.

Complex Tables are Missing ID or Headers Attributes

Data tables have multiple logical levels of row or column headers and lack the necessary coding associating the data cells with their respective headers. This issue is a violation of 1194.22(h) in Section 508 and 1.3.1 in WCAG 2.0.

Add id= and headers= attributes to all cells to correctly associate data cells with their respective row and column headers. For further assistance see http://www.hhs.gov/web/policies/webstandards/htmltable.html  and http://webaim.org/techniques/tables/data.
