Removing Column in GroupingGrid

How to delete a row in a bound grouping grid? I noticed that by just selecting the field and pressing delete doesn''t work. I''ve created an unbound field, and changed it to a pushbutton type. what code goes into that button to delete the row from the grid and change the row state of the datatable to deleted. thanks in advanced!

Here is code that will delete the current record in a GridGroupingControl.
int pos = this.grid.Table.Records.IndexOf(this.grid.Table.CurrentRecord);
if(pos > - 1)
	this.grid.Table.Records[pos].Delete();

Here is some code you can use in the ButtonClicked event.
private void gridGroupingControl1_TableControlPushButtonClick(object sender, GridTableControlCellPushButtonClickEventArgs e)
{
	int row = e.Inner.RowIndex;
	int col = e.Inner.ColIndex;
	GridTableCellStyleInfo style = e.TableControl.Model[row, col];
	//get some record data
	GridRecordRow grr = style.TableCellIdentity.Table.DisplayElements[row] as GridRecordRow;
	DataRowView drv = grr.GetData() as DataRowView;
	Console.WriteLine(drv[0].ToString() + " " + drv[1].ToString() );
}

for the code you posted bellow, that will only work if the row is selected. so it work work if i just click the delete button without first selecting the row. any ideas how i could do this? >Here is code that will delete the current record in a GridGroupingControl. > >

Try this code.
private void gridGroupingControl1_TableControlPushButtonClick(object sender, GridTableControlCellPushButtonClickEventArgs e)
{
	int row = e.Inner.RowIndex;
	int col = e.Inner.ColIndex;
	GridTableCellStyleInfo style = e.TableControl.Model[row, col];
	GridRecordRow rec = style.TableCellIdentity.Table.DisplayElements[row] as GridRecordRow;
	if(rec != null)
	{
		int pos = this.gridGroupingControl1.Table.Records.IndexOf(rec.ParentRecord);
		if(pos > -1)
			this.gridGroupingControl1.Table.Records[pos].Delete();
	}
}
