GridGroupingControl - Remove dotted border in GroupDropArea.DragColumnHeaderText

Dear Syncfusion Support,

We are using V 4.2.0.37.

we are able to change gridGroupingControl1.GridGroupDropArea.DragColumnHeaderText. But we also want to remove the dotted border also..

We tried handling GridGroupDropArea_DrawCell and GridGroupDropArea_DrawCellDisplayText events too.

Can you plz let us know how to achive this?

Hi Rajani,

You can use the GroupDropArea.PrepareViewStyleInfo event to change the appearance of the groupdrop area text in a grid. Below is a code snippet.

private void GroupDropArea_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
GridGroupDropArea area = sender as GridGroupDropArea;
GridGroupDropAreaModel model = area.Model as GridGroupDropAreaModel;
GridTable table = model.Table;
if (table.TableDescriptor.GroupedColumns.Count == 0 && e.RowIndex == 2 && e.ColIndex == 4)
{
e.Style.BackColor = Color.Blue;
e.Style.Borders.All = new GridBorder(GridBorderStyle.Solid);
}
}

Thanks,
Haneef

Haneef,

In the condition if (table.TableDescriptor.GroupedColumns.Count == 0 && e.RowIndex == 2 && e.ColIndex == 4),

are values 2 and 4 always fixed? Can we take them as constants? Cause my grids have different settings in different screens. So, would like to if I can replace this condition with any thing like TableCellIdentity.TableCellType == "some thing"..
