The following line leaves the visual lines of the child templates selected:
this.radGridView1.ClearSelection()

To workaround the issue use this.radGridView1.TableElement.UpdateView() after clearing the selection.

I have a problem with read only columns. 
When I paste a value (CTRL+V) on a cell from a read only column the value from that cell is changed with the value from the clipboard.

FIX. RadGridView - exception when BestFitColumns is called during data update

You cannot changed the value of a check box cell for more than one child rows in object relation hierarchy.

If the child template of a grid has a HtmlViewDefinition and AutoSizeColumnsMode property set to Fill, the cells are not measured properly when the row is resized horizontally.

1. Create a new project with RadGridView and bind it.
2. Add a button and when handling its Click event set the CurrentRow to null.
2. Run the project.
3. Start narrator.
4. Sort by some column.
5. Click the button.

In html view definition and hierarchy mode, the RadGridView throws exception when the TableElement is in explorer bar mode.

It is necessary to implement GetHashCode to avoid collisions when using this object in dictionaries

ADD. RadGridView - add row selection with Space in MultiSelection mode
Notice: This functionality works only in multiselection and EditMode different than
RadGridViewBeginEditMode.BeginEditOnKeystrokeOrF2
RadGridViewBeginEditMode.BeginEditOnKeystroke

To reproduce use the code below and try to type in "000" in a cell

            GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn("Phone");
            radGridView1.Columns.Add(comboColumn);
            comboColumn.DataSource = new string[] { "0", "00", "000", "0001" };
            comboColumn.Width = 200;
            comboColumn.DropDownStyle = RadDropDownStyle.DropDown;
            comboColumn.AutoCompleteMode = AutoCompleteMode.Suggest;

When the BeginUpdate and EndUpdate methods of RadGridView are used, the top summary row occurs twice when grouping is performed.

To reproduce:
1.Set the column AutoCompleteMode to suggest
2. Type a letter which does not exist in the records (if you have A, B, and C, use D)
3. Press escape
4. Type in another letter which does not exist => the exception is thrown

The GridRowBehavior is trying to access the AutoCompleteAppend of the element, which is null, while we are in Suggest mode.

1. Create a new project with RadGridView and bind it.
2. Setup column groups view.
3. Change some column and set the data source again on button click.
4. Run the project

Horizontal scrolling when multiple selection is performed by mouse.

The drag and drop of rows or columns to scroll the grid if the target item is not visible.

When a user groups the grid by a certain column and then attempts to drag the column back to the header, column reorder is possible, even though the AllowColumnReorder  is false.

The following strings on the print settings dialog of RadGridView cannot be localized: "Page fit mode", "Print:", "Alternating row color", "Summary cells"

When RightToLeft is enabled in RadGridView and you try to print it, the layout of the pages is messed up.

"IsContainedIn" and "IsNotContainedIn" operators currently not work properly with composite values like: "1, 2, 3"

When a RadGridView instance is initialized in the Form's constructor, the grid is not assigned a binding context.
Note: This is a desired behavior.
