GGC: need custom group selection processing

[Konstantin]

I am using GGC. In my application loaded grid records are initially grouped by one column (fixed one). I need user to have ability selecting only whole groups, not single records.

The problem is that I don't know how to process range selection with collapsed groups - i need to add underlying records to grids selected records collection. And I don't know which events I can use in order to detect which groups are being selected: CellMouseDown (neither CellMouseUp ) doesn't occur when clicking on a collapsed group header.

Thank you for your help.

PS: Btw, Click event is not what I need as I need user to be able to make range selections (with mouse drag&drop multiselection) or with a keyboard (SHIFT + arrows)

Hi Konstantin,

You can handle the TableControlMouseDown event and add related records in a group to selected record collection. Here is a code snippet to show this.

private void gridGroupingControl1_TableControlMouseDown(object sender, GridTableControlMouseEventArgs e)
{
Point pt = new Point(e.Inner.X,e.Inner.Y);
GridTableCellStyleInfo style = e.TableControl.PointToTableCellStyle(pt);
Element el = style.TableCellIdentity.DisplayElement;

Group mGroup = el.ParentGroup;
//Check the CaptionRow.
if( mGroup.Name == "Col1" && el.Kind == DisplayElementKind.Caption )
{
foreach(Record rec in mGroup.Records)
e.TableControl.Table.SelectedRecords.Add( rec );
}
}

Please refer to the attached sample for more details.

Hello, Haneef!

Thank you for reply, was already desperate to get it.

Sadly, your snippet doesn't help me to make SLIDE selection (e.g. mouse down on one header, up on another).
