Delete records in selected range from the datasource

[Lance]

i am able to retrieve a list of selected records in a GGC via: Me.ggc.TableModel.SelectedRanges

i used:
Me.ggc.TableModel.Rows.RemoveRange()

but apparently it only unselect the selected rows. how do i delete the records from the ggc instead of unselecting?

You can try using

this.gridGroupingControl1.Table.DeleteRecord

Or, you can work directly with your datasource and use methods on it to delete its records.

With the 3010 code base, if you use the new record selection support,

this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;
			this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;

then this button handler will delete the selected records.

private void button2_Click(object sender, System.EventArgs e)
{
	foreach(SelectedRecord r in this.gridGroupingControl1.Table.SelectedRecords)
		this.gridGroupingControl1.Table.DeleteRecord(r.Record);
	
}

You can try code like this.

private void button2_Click(object sender, System.EventArgs e)
{
	ArrayList recs = new ArrayList();
	foreach(GridRangeInfo r in this.gridGroupingControl1.TableModel.Selections.GetSelectedRows(true, false))
	{
		for(int row = r.Top; row <= r.Bottom; ++row)
		{
			GridTableCellStyleInfo style = this.gridGroupingControl1.TableModel[row, 1];
			GridRecordRow rr = style.TableCellIdentity.DisplayElement as GridRecordRow;
			if(rr.ParentRecord != null)
				recs.Add(rr.ParentRecord );
		}
	}

	foreach(Record rec in recs)
		this.gridGroupingControl1.Table.DeleteRecord(rec);
}

cool! the codes work great! however, it seem pretty tough to find out what methods/properties to use in order to achieve what i want...
