How to get selected rows of a GridGroupingControl

[Cuong Luc]

Hi,

I''ve searched alot but couldn''t find out how to get the selected rows in a GridGroupingControl (I use AllowSelection = GridSelectionFlags.Any to allow user to select multi rows).

I''ve tried with gridGroupingControl.Table.SelectedRecords but it was empty although I have some selected rows in the grid.

Please help me with this.

Thanks and regards.

Hi Cuong,

Use the Model.Selections property to manages selected ranges in the grid. It allows you to add, remove and get selections, determines selection state of a specific cell.

//Get the selected rows from the groupin grid.
GridRangeInfoList range = this.gridGroupingControl1.TableModel.Selections.GetSelectedRows(true,true);
foreach( GridRangeInfo info in range)
{
Element el = this.gridGroupingControl1.TableModel.GetDisplayElementAt(info.Top);
Console.WriteLine( "Selected RowIndex : " + info.Top + " =====> " + el );
}

Thanks,

Thank you so much, Haneef. You''ve helped me to solve it. The grid is quite nice :).

One more thing, does GridGroupingControl have a property to set the last column always fill the remaing space of the form (like FillLastColumn property of GridListControl)?

Hi Cuong,

There is no built-in support for this. But you can handle the TableModel.QueryColWidth event and set the width of the last column. Below is a code snippet.

private void TableModel_QueryColWidth(object sender, GridRowColSizeEventArgs e)
{
GridTableModel model = sender as GridTableModel;
int findex = model.Table.TableDescriptor.VisibleColumns.Count - 1;
int index = model.FieldToColIndex( findex);

if(e.Index == index )
{
int cwidth = this.gridGroupingControl1.ClientSize.Width;
int twidth = model.ColWidths.GetTotal(0,e.Index-1);

e.Size = cwidth - twidth;
e.Handled = true;
}
}

Let us know if this helps.
