My problem is, when I tab through the controls and go to Ultra grid, it selects the entire row, but I only want to get the focus only on the check box and make a selection by hitting space bar, but as of now when I hit the space bar or tab or left or right down or up arrow it won't check the check box instead it keeps scrolling to the next row and so on. Can someone please help me with the sample code to just select the check box and able to check the check box with the space bar.

By the way, the check box is dynamic (please see the designer view image attached). Here is the code in the grid initialization I used (I know I commented lot of lines as I tried lot of options but none worked for me).

private void grdEmployeeRoles_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
try
{
UiHelper.SetDefaultUltraGridLayout(e.Layout);
UiHelper.SetGlobalGridSettings(grdEmployeeRoles);
if (grdEmployeeRoles.Rows.Count >= 0)
{
if (!e.Layout.Bands[0].Columns.Exists("Role_Selected"))
{
e.Layout.Bands[0].Columns.Insert(1, "Role_Selected");
}
this.grdEmployeeRoles.DisplayLayout.Bands[0].Columns["Role_Selected"].TabIndex = 0;
this.grdEmployeeRoles.DisplayLayout.Bands[0].Columns["Role_ID"].TabIndex = 1;
this.grdEmployeeRoles.DisplayLayout.Bands[0].Columns["Role_Description"].TabIndex = 2;
this.grdEmployeeRoles.DisplayLayout.Bands[0].Columns["Predefined"].TabIndex = 3;
foreach (Infragistics.Win.UltraWinGrid.UltraGridColumn grdEmployeeRolesColumn in e.Layout.Bands[0].Columns.All)
{
switch (grdEmployeeRolesColumn.Key)
