Hi Dongxian,
Regarding Question 1:
>>>>>>>>>>>>>>>>>>
You can try setting the SupportFocusControl property of the DropDownGridCellRenderer to true in DropDownGridCellRenderer constructor. Below is a code snippet
public class DropDownGridCellRenderer: GridDropDownGridCellRenderer
{
GridControlBase grid;
public DropDownGridCellRenderer(GridControlBase grid, GridCellModelBase cellModel)
: base(grid, cellModel)
{
this.SupportsFocusControl = true;
DropDownButton = new GridCellComboBoxButton(this);
this.grid = null;
}
//////////// YOUR CODE /////////////
}
Regarding Question 2:
>>>>>>>>>>>>>>>>>>
The reason is that you are not setting the checkboxoptions property in a cell. Here is a KB article that discuss with purpose of CheckBoxOptions in a grid's cell.
