I think It would be great  the AUTOCOMPLETEBOX (integrated with FilterExpression)  insted of the TEXTBOX for filtering in riadgrid. 

It's too tedious adding a custom filter template , persisting and restoring filter values after postbacks, build the filterexpression manually etc.

I'm aware the checkList can provide similar functionality but it't not so clear,  intuitive, ergonomic and easy to use for current user.

Default values are provided for fields with non-string type in insert mode when RadGrid is bound using Model Binding. The reason behind it, is that the Insert item of the RadGrid is being bound similar to the edit Item and values are then provided by the framework.

Please create an option to remove the default values when inserting a new record.

As shown in the attached screen, please keep the column headers Fixed or Visible so they are still visible when users scroll down to see the other data, for both RadGrid and PivotGrid:

Because the TBODY THEAD and TFOOT elements are rendered in an incorrect order which is "header -> footer -> body" rather than "header -> body -> footer", the screen readers fail to present the data properly.
