The problem exist for NotifyCollection - CollectionChanged event also. Filter events too.

When you set the value of unbound column in bound mode of RadGridView, the cell is not updated.

The CellClick event is fired when the mouse button is released after scrolling.

The GridSpinEditor of RadGridView changes its value automatically to its maximum.

I have a radform, drop a gridview on it, go into property builder for the gridview and add a textbox column, make the column read only, do not allow sorting, grouping, or adding, do not show the group panel or the column header row.  The top border is missing.

1. Create a new project with RadGridView
2. Set ColumnGroupsViewDefinition
3. Save the layout by calling the SaveLayout method
4. Load the layout by calling the LoadLayout method

1. Create a new project with RadGridView
2. Create a new ColumnGroupsViewDefinition
3. Change the ViewDefinition property in the Designer.cs file before calling the EndInit method
4. Run the project

1. Drag a RadGridView on a form.
2. Set the EnableFiltering and ShowHeaderCellButtons to true.
3. Fill the grid with data and run the project.
4. Open the filter popup and type something in the text field.
5. Press enter key and the popup will be closed without applying the filter.

1. Create a new project and open a form at design time
2. Add RadGridView
3. Add a GridViewDecimalColumn
4. Set its TextAlignment property to MiddleLeft
5. Run the application

use attached project with pre-build release version of assemblies included in the 'telerik-devbranch-release' folder
1. Create a new project with RadGridView and bind it to a data source. The data source should contain a large number of rows (30000 for example)
2. Add a check box column
3. Run the project
4. Sort by a column (different from the checkbox column)
5. Check a checkbox
6. Click on some other column or row

1. Create a new project with RadGridView
2. Enable the multiple row selection and set the second column to be read only
3. Run the project
4. Start selecting from the "add new row" and the second column
5. Move the mouse down
6. Release the mouse button on the second column

The ValueChanged event of RadGridView is not fired when you select a new item of RadDropDownListEditor in AutoCompleteMode.Append.

IMPROVE. RadGridView - expose the color dialog form in GridColorPickerElement

Currently there is SortDirectionArrowPrimitive allowing you to set an arrow for both states, but this way you cannot use custom image for the different sort operations.

There is a bug regarding the filtering of the grid, in the GridViewComboBoxColumn.
The filtering result displays wrong value.  
The bug accurse when:
   - Select a value form a GridViewComboBoxColumn.
   - Clear Filtering of the grid.
   - write a new value in the filtering GridViewComboBoxColumn cell, before living the cell.
The grid is filtered with the previous selected value.  
Note: the bug accurse only when the ReadOnly Property of column is off.

Allow hiding of whole group in ColumGroupsViewDefinition by adding Visibility property to ColumnGroup class.

ADD. RadGridView - add support for sorting GridViewComboBoxColumn by Display or Value member in unbound mode.

There are 2 main problems in this functionality:
A) User has to click the filter check box twice to get the state changed for the first time. That is unacceptable, It must work from first click from first click check box must change its state.
B) Parameters of FilterChanging event are absolutely useless and what is worse they even lie about real state of the filter.
C) If I want to edit in column editor FilterDescriptor property of the column some maybe old dialog window appears because whatever I set here it does not change anything.

Currently RadGridView supports only copy & paste between grid cells

The ValueChanged event of RadGridView is fired when the RadDateTimeEdior has null value and the popup is opened.
