Grid Grouping Control

is there a way to freeze the grouping grid caption text when scrolling to the right.

thanks

Hi Prem,

Yes. You need to handle the TableControlDrawCell event and draw the GridCaption cell text using DrawString method. Below is a code snippet

//Form Load.
this.grid.TableControl.HScrollPixelPosChanged +=new GridScrollPositionChangedEventHandler(HScrollPixelPosChanged);

private void TableControlDrawCell(object sender, GridTableControlDrawCellEventArgs e)
{
GridTableCellStyleInfo style = e.Inner.Style as GridTableCellStyleInfo;

if( style.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionCell
&& e.Inner.ColIndex ==0 && e.TableControl.TableDescriptor.Name == "ParentTable" )
{
e.Inner.Cancel = true;
string s = e.Inner.Style.Text;
e.Inner.Style.Text = string.Empty;

Rectangle rect = e.Inner.Bounds;
rect.Location = new Point(0,rect.Y);

e.Inner.Renderer.Draw(e.Inner.Graphics ,e.Inner.Bounds,e.Inner.RowIndex,e.Inner.ColIndex,e.Inner.Style );
e.Inner.Graphics.DrawString(s,e.Inner.Style.GdipFont,new SolidBrush(e.Inner.Style.TextColor),rect);

e.Inner.Style.Text = s;
}
}

private void HScrollPixelPosChanged(object sender, GridScrollPositionChangedEventArgs e)
{
GridTableControl tc = sender as GridTableControl;
tc.RefreshRange(GridRangeInfo.Row(1));
}

Thanks,
Haneef
