Hi.
I used RadDropDownListEditor in my gridview.when press tab Key and enter it,and start write with keyboard
i have a problem.but when enter this cell with Mouse I don't have any problem.
I used RadDropDownListEditor in ver2011 and don't have any problem.
but now Use ver2012.this problem is exist.

private void GrdCheck_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)

{

if (GrdCheck.CurrentColumn is GridViewComboBoxColumn)

{

if (GrdCheck.CurrentColumn.Name.ToString() == "BankRef")

{

RadDropDownListEditor comboBoxEditor = this.GrdCheck.ActiveEditor as RadDropDownListEditor;

if (comboBoxEditor != null)

{

comboBoxEditor.EditorElement.StretchVertically =

false;

comboBoxEditor.DropDownStyle = Telerik.WinControls.

RadDropDownStyle.DropDownList;

comboBoxEditor.DropDownSizingMode =

SizingMode.UpDownAndRightBottom;

            }
            }

}

private void GrdCheck_CellEditorInitialized(object sender, GridViewCellEventArgs e)

{

if (GrdCheck.CurrentColumn.Name.ToString() == "BankRef")

{

RadDropDownListEditor cmb = GrdCheck.ActiveEditor as RadDropDownListEditor;

if (cmb != null)

{

((

RadDropDownListEditorElement)(cmb).EditorElement).DisplayMember = "Descr";

((

RadDropDownListEditorElement)(cmb).EditorElement).ValueMember = "Id";

((

RadDropDownListEditorElement)(cmb).EditorElement).DataSource =DtBankCheck;

((

RadDropDownListEditorElement)(cmb).EditorElement).SelectedIndex = -1;
