CheckBox Click Followed by Context Menu Popup

[Administrator]

Hi! I''m using v 3.2.1.0 GridGroupingControl. In the event handler for context menu popup, I needed to evaluate if the current row has changed. So I used the this.Grid.Table.GetInnerMostCurrentElement() to get a DataRowView and set the menu enable state Based on its DataRow''s RowState.

It works just fine except if the previously changed cell is a checkbox. The current element seems to stay as the checkbox cell, instead of the right-mouse clicked cell. How do I make it consistent?

Thanks,
Billie

Here is a forum thread that discusses displaying a context menu and getting the cell under the click.

http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=20103

It uses the TableControlCellMouseUp event to show the menu. The e.Inner.RowIndex and e.Inner.ColIndex pick out the row and column.

But if you are using our XPMenus so that you do not control the popup action, you can handle the BeforePopUp event to catch teh click DataRowView.

private void popupMenu1_BeforePopup(object sender, Syncfusion.Windows.Forms.CancelMouseEventArgs e)
{
	Point pt = this.gridGroupingControl1.TableControl.PointToClient(Control.MousePosition);
	int row, col;
	if(this.gridGroupingControl1.TableControl.PointToRowCol(pt, out row, out col))
	{
		GridTableCellStyleInfo style = this.gridGroupingControl1.TableControl.GetTableViewStyleInfo(row, col);
		GridRecord record = style.TableCellIdentity.DisplayElement.ParentRecord as GridRecord;
		if(record != null)
		{
			DataRowView drv = record.GetData() as DataRowView;
			if(drv != null)
			{
				Console.WriteLine("{0} {1} {2}", drv[0], drv[1], drv[2]);
			}
		}
	}
}

Thank you, Clay. It works fine with a flat table or the top level of parent table when all rows are collapsed, but not a child table of a hierarchical grid.

You have to get the proper TableControl when you have nested tables. Here is a little sample that uses the TableControlCellClick event. The proper table is passed in as an event arg in this event.

Clay,

Thank you for the sample, but the CellClick event happens after the context menu popup event. The complication here is that the GridGroupingControl is inside of a user control which has a context menu merged with that of the GGC. It needs to do some processing in the menu Popup event.

Any other alternatives? Thank you in advance.

Try code like:

Point pt = this.gridGroupingControl1.TableControl.PointToClient(Control.MousePosition);
Element el = this.gridGroupingControl1.TableControl.PointToNestedDisplayElement(pt);
if(el is GridRecordRow)
{
	GridRecord rec = el.ParentRecord as GridRecord;
	if(rec != null)
	{
		DataRowView drv = rec.GetData() as DataRowView;
		Console.WriteLine("{0} {1} {2}", drv[0], drv[1], drv[2]);
	}
}

Clay,

It worked perfectly.
Thank you much.
