We recently added row group functionality to our grids and we and our users are very happy with this.

Only thing that bothers us is the drop functionality on the grouppanel. We have an wish to make the drop functionality of the grouppanel much more intuitive. Especially when the RadGrid is already grouped on multiple columns.

The marker to indicate where the user will drop an existing grouping column is shown at the begin and the end of the group column connector between groups. Except in front of the first group column. Can the same behavior be added to the end of the last grouped column?

 This case can be reproduced on the RadGrid Grouping demo on your site:

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.

Please could you add an option to the NextPrevNumericAndAdvanced pager mode to allow the Page Size RadTextBox to be displayed as a RadComboBox like the NextPrevAndNumeric pager.
This would help us to have a more consistant look and feel between the 2 pager modes.

It would be nice to have a "remove" button on the edit template, where the user could delete an image that was uploaded and saved on the database before. 

Is any option to use RadGrid in disconnected mode. So when user lost connection with internet(intranet), he can continue to work with grid - add new record, edit records. In html 5 appear such technologies like HTML5 Storage,Web Sql. Is it any way to interact with them?

Please add a setting for the Grid in batch edit mode to enable prompting to save changes.  The prompt should occur when navigating away from the page, when paging, when filtering, when refreshing, or any other action that would cause loss of changes without a save.
For details on how I implemented this manually, please see ticket 933229.

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.

The setting FilterType="CheckList" does not affect detail rows in the RadGrid.  Only "Classic" filtering is implemented for detail rows. I (and definitely users) expect the same filtering functionality on both main and detail rows.

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.

I brought this to Telerik's attention 4 years ago. The grid Pager is a poor location for the built-in loading image because it is not clearly visible in a number of scenarios. First off, it is small and tucked in the corner, which makes it hard to see. But there are other scenarios where it is completely invisible. 

If the grid height is fixed and larger than the screen size, the entire pager is not visible unless the user scrolls the window. So, the loading image will not be visible when users take actions like sorting/editing/deleting/filtering which tend to occur towards the top of the grid.

And, if the grid has Paging disabled, then the pager and built-in loading image will NEVER be visible.

I understand that one can add a custom loading image which would work better. And if asked, Telerik can provide a couple dozen lines of custom javascript which will move the loading image for a grid. But If your project has a large number of grids, adding code to each is untenable. And at the end of the day, this should be a built-in feature of Rad Grid, not something that needs to be hacked to work appropriately.

RadWindow used to have a tiny loading image in the status bar which was invisible in a number of scenarios, most notably when the status bar was disabled. The Rad Window team saw fit to move the loading image to the center of the Rad Window where it belonged. This was years ago. For some reason, the Rad Grid team has not seen fit to do the same. Why is the RadWindow team aware of and responsive to concerns about the usability of their control and the Rad Grid team is not?

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.
