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.

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.

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

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.

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

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.

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

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.

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. 

Checking the select column header cell won't select the rows that are hidden. Thus in a grouping scenario, the group checkbox to an intermediate state. This will lead to confusion that there are still un-selected items, while all visible items are selected.

In this case, we have an enum column. When the DataFilter dialog is shown and we click to enter the filter value, an exception is thrown.

System.ArgumentException: 'An item with the same key has already been added.' when the data source contains DateTime with the same hour, minute, and seconds part (only milliseconds are different):

 

The CellSpacing property value is not taken into account. This property has different value in different themes.

In this case, the RadGridView AutoSizeRows and ColumnGroupViewDefinition are enabled. The rows will have different heights depending on the cell content. When exporting the RadGridView to PDF, the rows will have equal size and won't respect the current size in the view. Thus longer text in a cell will be cut off. 

The same behavior is observed when exporting to PDF or XLSX. In addition, this is also observed when printing the RadGridView.

In the current scenario, when clicking on the checkbox inside a GridViewCheckBoxColumn, the CellBeginEdit event will be called. If we cancel the event by setting the Cancel property to true, the CellBeginEdit will be called twice.

In this scenario, we have custom RadListFilterPopup. There could be a scenario in which we don't need the default menu items( input textbox, list of distinct values, buttons). If we override the CreateListFilterMenuItems() method and don't call the base code, NullReferenceException will be thrown in the Dispose() method.

In this scenario, the MultiSelect option of the control is enabled. If we click and hold the mouse to select multiple cells and go over a merged cell, NullReferenceException is thrown.

Steps to recreate:

• click on the button on the top row
• press the down key on the keyboard
• Press Space key to select new button, the button on the top row is clicked

In the following scenario, we have enabled the pager functionality of the control. If we move to a different page and then set the DataSource to Null, the page index will not be reset.
