To work this around you can set the EnableColumnGroupsVirtualization to False.

Alternatively you can change the FrozenColumnCount before adding the columns, and reset it once the process is done. For example:

gridTriffDetails.FrozenColumnCount = 0;
 
gridTriffDetails.Columns.Add(newColumn);
gridTriffDetails.Columns.Add(newColumn1);
gridTriffDetails.Columns.Add(newColumn2);
 
gridTriffDetails.FrozenColumnCount = 1;

Currently the new item's properties are validated before editing their values, which is not intuitive, especially for Required, MinLength etc. The correct behavior would suggest that validation should be applied only to "confirmed" property values.

Available in the R1 2017 SP1 Release.

I have a custom column based on GridViewBoundColumnBase. In it I override GetCellContent. If I bind the column to a nested property (MyProperty.SubProperty), what I return in GetCellContent is not shown, instead the nested property's "raw" value is shown.

Attached is a project illustrating the issue.

Available in LIB version: 2017.2.703

the attached project displays a wpf radgridview bound to a list<person> via a viewmodel.
if you add a new row, enter some data, and tab through the values everything works fine.
if you add a new row,  enter some data, and click the rowheader of the new row, the grid displays incorrect values (see the attached screenshots.pdf)

Available in the R1 2017 SP1 Release.

1.   Run the sample application.

2.   Scroll to the last item.

3.   Begin to resize the window. The direction is irrelevant. Only the horizontal scrollbar needs to be visible.

4.   Observe that in the beginning of the resizing, the scrollbar auto scrolls upwards a little and the last item is half hidden.

Available in LIB version 2017.1.213 , it will be also available in the R1 2017 SP1 Release.

InvalidOperationException, when sorting or filtering GridView and an observable immutable collection is used in a multithread application.

Not all of the FilteringControl elements have automation IDs. This fact prevents the proper usage of some automation frameworks.

DataFormatString is not respected when exporting RadGridView to .xlsx file and a GridViewDataColumn is bound to a nested property.
