Tab Stop behavior in a GridGroupingControl

[Sameer Khan]

Is there a way to control the tab stop for individual columns in a GridGroupingControl

Hi Sameer,

Thanks for your interest in Syncfusion products.

Please try handling the TableControlCurrentCellKeyDown event with the following code snippet. This prevents the tabbing to the column2 in gridgroupingcontrol.

private void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, GridTableControlKeyEventArgs e)
{
       GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
       if (e.Inner.Shift == false && e.Inner.KeyCode == Keys.Tab && cc.ColIndex == 1)
       {
                 e.Inner.Handled = true;
                 cc.MoveTo(cc.RowIndex, cc.ColIndex +2);                    
       }
       else if (e.Inner.Shift == true && e.Inner.KeyCode == Keys.Tab && cc.ColIndex == 3)
       {
                 e.Inner.Handled = true;
                 cc.MoveTo(cc.RowIndex, cc.ColIndex - 2);
       }
}

Thank you for the response; but this does not answer my question.

I was looking for a way to control the tab stops, since these columns can be re-arranged, and indexes are never a good thing.

Also, when I am programatically changing the index around [using move to], I might land in a cell which needs to have it's tab stob disabled.

I could get around all of this [I guess] by making the columns disabled. But was hoping that there would be some property on the column itself.

Hi Sameer,

Sorry for the inconvenience caused.

If column reordering has to be done, then you can make use of HeaderText property instead of column index. Please try the following code snippet.

void TableControl_CurrentCellKeyDown(object sender, KeyEventArgs e)
{
    GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
    if (e.Shift == false && e.KeyCode == Keys.Tab  && cc.Renderer is GridTextBoxCellRenderer )
    {
          if (cc.ColIndex < this.gridGroupingControl1.TableDescriptor .Columns .Count)
          {
               if (this.gridGroupingControl1.TableDescriptor.Columns[cc.ColIndex].HeaderText == "CustomerName")
               {
                    cc.MoveTo(cc.RowIndex, cc.ColIndex + 1);
               }
          }
    }
}
