Provide the ability for the developer to configure the grid so that the Group By box appears _below_ the CommandItem

It would be useful for the header cell for Sort-able columns to display an indication that the column can be sorted.  This is useful to users when not all columns are sort-able, so they know which header cells will trigger resorting.

Elsewhere in our application, we use a double headed arrow icon to indicate use can click on header to resort on the column; the app displays the up or down arrow indicating when sort order is active.

Suggest adding a third Sort-Image-URL attribute to specify an image to use when column is not sorted ascending or descending.

At present, best I can do declaratively (w/o custom coding) is the set one of the HeaderStyle-Font properties (for example the HeaderStyle-Font-Underline) to provide a visual indication that column is sort-able.

If the user's browser supports html5 local storage, I'd like for the RadGrid to be able to save/load its settings from there for things like page size, column order, sorting, etc.  Other controls may be able to do this as well.

When doing batch edits on a grid if you delete a row, the row is no longer visible in the grid but it is not actually deleted until users click the 'Save' button. This has led to some confusion for our users who delete the rows then navigate off the page w/o pressing save. They think they successfully deleted the rows but when they return to the grid the rows are still present.

We have added logic when navigating away from the page that checks and prompts users if there are unsaved batch edit changes, but in case of deleted rows, when they look at the grid, there is no indication about the deleted rows so they are unaware that the rows were not actually deleted.

We like the idea of not deleting the rows until the user presses the save button, but maybe the delete action should not remove the row from the grid and instead simply strike it out, or put a 'marked for deletion' flag or do something visual to keep the row on the grid but make it obvious that it has been marked for deletion. This way users will not be confused and will know that they must click the Save for the change to take effect.

Auto-Fit column width when exporting to excel using Format="Xlsx"

 I'd really like to have the columns automatically adjust to fit the width of the content.

Hello,

I would like to have the group footer display the total items count in that particular group but the way the radgrid is designed it almost seems impossible and it is requirement for us. I would also appreciate if you would consider adding the aggregate for the entire group in the group footer and the entire grid in the grid footer. 

Thanks

It will be interesting if the literals "From" and "To" in the filter area of the GridDatetimecolumn take their values from resources, as all other controls inside RadGrid. This way will be easier to localize the grid.

If the first column contains a list of Countries and you select for instance USA, the filter item in next column, which contains a list of Cities, should contains only cities from USA.

Add support for custom paging in the RadGrid Virtualization functionality. The idea is to enable the retrieval of part of the data from the source of data instead of retrieving all of the data every time.

Without this feature the optimization technique is to cache the data source.

Example is available at http://www.telerik.com/support/kb/aspnet-ajax/grid/details/virtualization-and-custom-paging

User friendly Grid filtering...
I developed a custom feature where I display the filter expression used in a grid. This is very helpful so that users do not have to guess or remember what exactly they filtered on. And it provides a single click to clear all the filters at once. Before, all they saw was that certain columns are being filtered by, but they don't see what the filters actually are (EqualTo, Not EqualTo, StartsWith,,,etc) and they had to clear one filter at a time to get rid of all filtering.
There is not much to it but it's subject to break if Telerik makes changes to the their filtering mechanism (which did happen). It would be nice if this feature can be standard so it will be part of Q.A after any changes to the Grid.
Attached is a working sample page to see this in action. See comments in code.

Need the ability to Sort Grouped Items (ex. Salesperson) by the value of another Grouped Item (Sum of Sales).

Currently, there is NO WAY to sort a list of Salespeople by Total Sales. You can only perform an alpha sort on Salesperson's Name.

So, if you have a list of 100 Salespeople and their total product sales across dimensions like (product, geographic) you will have to MANUALLY look through and note who are your top Salespeople !!!!!!!!!!!

How can this be acceptable ??

An alpha sort on Salesperson is the best you guys can do??

Currently the RADGrid  only supports creation of columns on the server side. With todays browsers capabilities it is important to support client side column creation as well.

The GridCheckBoxColumn cannot handle null values in a bit field. 

I would like to be able to bind the checkboxcolumn to a bit field that allows nulls. The checkbox should be checked when the value is true, unchecked when it is false, and filled when it is null.

The current solution is to use the RadButton inside a GridTemplateColumn and add custom togglestates, but this solution is not documented and it is very time intensive for something that should be quick and simple. It requires a lot of coding to update or insert a record.

In RadGrid, we can use the ClientSettings.Scrolling.UseStaticHeaders property to have a fixed header when scrolling the grid. This requires a fixed height of the grid. However, what if we do not want a fixed height of the grid, but rather want the grid to flow down the page, using as much space as necessary do display its records. In such a scenario, the grid header will disappear when we scroll down the page.
I have implemented a kind of fix for this in one of my projects. Instead of trying to explain how it works, I have prepared an example. You can find it here:

Maybe some of you can suggest even better solutions to the scenario I have described. Comments are welcome!
