1. Group by some column or create hierarchy.
2. Select all from the parent header check box or in the header.
3. Expand parent row
4. As a result, the row expands, but selection disappears.

In this case, we have GridViewCalculatorColumn. The cell value is 123, for example. Trying to edit the cell value, the RadCalculatorEditor reset the cell value to 0. 

In this case, we have null values in some cells. When filtering the column, these cells will be ignored. 

While the Excel-Like filtering dialog is open and the mouse is over the RadGridView rows, moving the mouse wheel will scroll both the filtering dialog and the rows.

EndEdit() method is not called of IEditableObject if an exception is thrown while setting a null value to the bound property

In this case, the RadGridView is in the Self-Reference hierarchy. When the value of a cell is changed runtime, we are populating the bound (BindingList) collection with new items. All BindingList notifications will be called, however, the internal RadListSource in the RadGridView won't be updated, thus leading to a ArgumentOutOfRangeException.

In the description of the RowIndent property is mentioned that this will indent groups and hierarchy rows.  However, it can indent group rows only. 

Holding CTRL + C on a cell for a couple of seconds will throw ExternalException. 

In this scenario, the Browsable(false) attribute is set to both properties which are used to create the self-referencing hierarchy. When the columns are predefined, running that application will freeze as the RadGridView could not correctly get the parent row. If the columns are auto-generated, this behavior is not observed. 

This is not exactly a real solution as setting the Browsable(false) attribute will remove the properties from the source. However, the control should not freeze the application.

The Excel-like filter in the SelfReference hierarchy is slow.

To reproduce the issue:
Click the first cell of a column
Scroll down and press Shift key and click the last cell of the column
Check that total rows label is 20.000 but selected cells label is less than 19.997

maskBoxColumn.FormatInfo = CultureInfo.CreateSpecificCulture("en-AE");

NullReferenceException occurs in a multi-select scenario when clicking (and holding the mouse button) on an empty area in the grid and the mouse leaves the boundaries of the control.

In this scenario, the RadGridView.DataSource property is set to Microsoft.EntityFrameworkCore.ChangeTracking.ObservableCollectionListSource. When the RadGridView.Rows.Remove() method is called an IndexOutOfRange exception is thrown.

 

1. I click a user control in the map view that has a row with value "Vite". This works fine because it doesn't have a lot of rows under the parent row.
2.Then I click the user control in the map view that has a row with value "TASÄ". This time the grid scrolls to an incorrect position. The corresponding row is a lot lower in the child list.

In a GridView, if there is at the same time in a column empty cells and the value (Blanks), the filter box will fail to open.

When I work with RadGridView component, the "RadGridView Property Builder" closes unexpectedly. It happens when I make the following steps:

1. RadGridView properties AutoSizeRow set to true.

2. Column Group properties ShowHeader set to false. 

In this case, the control has multiple columns. Some of them are not visible in the view, you will need to scroll to the end. When moving a DateTime column to the end of the control and editing twice its filter cell, a NullReferenceException is raised. 

I had the following code:
