Hi Supriya,

 

Thank you for your interest in Syncfusion products.

 

If you want to set focus to next row of parent table as well as child table while pressing down arrow key in gridgroupingcontrol, you can use “TableControlKeyDown” event and focus particular cell by using “MoveTo()”method and set the “GridSetCurrentCellOptions” as SetFocus. Please refer the below code,

 

Code:

this.gridGroupingControl1.TableControlKeyDown += new GridTableControlKeyEventHandler(gridGroupingControl1_TableControlKeyDown);

 

void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, GridTableControlKeyEventArgs e)

{

GridCurrentCell cc = e.TableControl.CurrentCell;

GridTable tablechild = this.gridGroupingControl1.GetTable("MyChildTable");

GridTableCellStyleInfo style = tablechild.GetTableCellStyle(cc.RowIndex, cc.ColIndex);

if (e.Inner.KeyCode == Keys.Down)  // pressing Down arrow key

{

if (tablechild.CurrentRecord != null) // child table

{

e.TableControl.CurrentCell.MoveTo(GridRangeInfo.Cell(cc.RowIndex + 1, cc.ColIndex), GridSetCurrentCellOptions.SetFocus);

}

else // parent table

{

e.TableControl.CurrentCell.MoveTo(GridRangeInfo.Cell(cc.RowIndex + 1, cc.ColIndex), GridSetCurrentCellOptions.SetFocus);

}

e.Inner.Handled = true;

}

}

 

Please let us know if you have any concern.

 

Regards,

Muthukumar K
