GridGroupingControl close form on DoubleClick

[Krijn Michiels]

Hi,

I use the gridgroupingcontrol as a datalist where use can select, sort, order records. After doubleclicking the record the app opens a new window.
the events I use or:
- TableControlCurrentCellActivating
=> show full selection line ( e.Inner.ColIndex = 0
- TableControlCellClick
- TableControlCellDoubleClick

Hi,

I use the gridgroupingcontrol as a datalist where use can select, sort, order records. After doubleclicking the record the app opens a new window.
the events I use or:
- TableControlCurrentCellActivating
=> show full selection line ( e.Inner.ColIndex = 0)
- TableControlCellClick
=> grab the current displayed datarow
- TableControlCellDoubleClick
=> open other window and close current

I keep getting NullReference exception(s) when the code exits the TableControlCellDoubleClick handler. I think the refresh method is called by the control itself and doesn''t know that is doesn''t exist anymore.

Any solution or work around would be great !

Hi Krijn,

make sure you set e.Inner.Cancel = true.

If that still gives problems close the form using a timer as follows:

{
	System.Windows.Forms.Timer t = new System.Windows.Forms.Timer();
				t.Tick += new EventHandler(t_Tick);
				t.Interval = 20;
				t.Start();
			}

		private void t_Tick(object sender, EventArgs e)
		{
	System.Windows.Forms.Timer t = (System.Windows.Forms.Timer) sender;
			t.Tick -= new EventHandler(t_Tick);
			t.Dispose();

                  myform.Close();

            }
