Add a mechanism to fix the current viewport (scrollbar position) when new items are inserted. Currently, when you insert items before the viewport's start, the scrollbar position is offset.

RadGridView provides two methods to bring an item into the view. We could extend these or create a new one to bring an item to a specific position.

Add a TextAlignment property to the GridView's AggregateFunctions to set the alignment of the resulting text. 
Apply to both Caption and FormattedValue simultaneously. 
This way we won't have to make custom ItemTemplates for the AggregateResultsList in each footer, when using AggregateFunctions out-of-the-box.

Can you add a grid-level option to hide any grouped columns automatically (rather than at the column level)?

I've tried creating a attached property behavior to do this (see attached), but it doesn't work well with auto-generated columns.

Right now, if you programmatically increase the RadGridView's font size, the columns get bigger to accommodate. So far, so good. But if you then make the font size smaller, the columns stay the same large-font width. 

Further, double-clicking the gridsplitter that separates the columns after the above procedure doesn't resize the column like it would if you'd manually resized the column and then double-clicking the gridsplitter - instead, nothing happens.

Finally, it would be nice to have a programmatic interface to autosize the columns, something like

MyGrid.Columns(0).AutoSize()

Thanks!

Add the "does not begin with" and "does not end with" to the list of filter parameters

PropertyChanged event is called for a cell with nullable value when is in edit mode and click on another cell

It would be very nice to have a "transpose" functionality in RadGridView. There are ways to transpose data instead of GridView, but this way it would be difficult to configure bindings, styles and other parameters. PivotGrid isn't suitable in this scenario because of lack of editing.

There is an example of what is needed: https://rotatedwpfdatagrid.codeplex.com/. I was successfully using this example with a standard WPF DataGrid, but I don't know how to accomplish this in RadGridView.

There are already a few threads about this feature:

Thank you!

The NullReferenceException is observed when the GridView is Grouped and rebound in the CellEditedEnded event handler.

I have a RadGridView with RadLinearSparkLines as a column showing ~100 trends.  I am looking to save all sparklines when I save screenshot.
I tried by querying the RadGridView for desired size after a call to Measure(), and pass it to the Arrange().  However, the RadGridView renders within the bounds of its actual size but not the desired size.  I also noticed that the desired size is not as tall as the size required to render all rows.
Is there any way I can save RadGridView as PNG with all rows rendered in the image?

Thanks in advance for any tips!

Exporting to Excel for hierarchical grid view i.e parent and child grid.
The Output Excel should be looks like drill down report which child report can be hidden/visible.
