CurrenCell change event in gridGroupingControl

[Prathima Venkobachar]

Hi,

I want to capture the cell value whenever there is a change in the cell value.
which event is better to use either:
this.gridgroupingControl.TableControlCurrentCellChanged
or
this.gridgroupingControl.TableControlCurrentCellChanging.

Thanks,

The Changing event is only raised once (on the first change by your user to the cell). It will not be raised again until teh user leaves the cell, then returns to teh cell, and starts to make another change to teh cell.

If you want to catch evey (intermediate) change, then the TableControlCurrentCellChanged event is better.

Thanks,

How can I get the current cell changed value..?
If the current cell is "price",
I want to set this value to another column in the grid.
How can I do this..?

Thanks,

To do what you described, I would suggest using TableControlCurrentCellValidating. This is hit once as your user leaves the cell. This code will then copy teh value in ParentName to the ParentDec column.

private void gridGroupingControl1_TableControlCurrentCellValidating(object sender, GridTableControlCancelEventArgs e)
{
	GridCurrentCell cc = e.TableControl.CurrentCell;
	GridTableCellStyleInfo style = e.TableControl.Model[cc.RowIndex, cc.ColIndex] as GridTableCellStyleInfo;
	if (style.TableCellIdentity.Column != null &&
		style.TableCellIdentity.Column.MappingName == "ParentName" &&
		(style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell ||
		style.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell))
	{
		string newvalue = cc.Renderer.ControlText;
		GridRecordRow rr = style.TableCellIdentity.DisplayElement as GridRecordRow;

		rr.ParentRecord.SetValue("ParentDec", newvalue);
	}
}

I want to do this as and when the user changes the cell value.
It is not necessary the user leaves the columns.
Is it better for me to use TableControlcellChanging event.

Thanks,

TableControlCurrentCellChanged is where you can catch each change by your user. You will also have to make sure the row id redrawn so you change to the other column is displayed imeddiately.

private void gridGroupingControl1_TableControlCurrentCellChanged(object sender, GridTableControlEventArgs e)
{
	GridCurrentCell cc = e.TableControl.CurrentCell;
	GridTableCellStyleInfo style = e.TableControl.Model[cc.RowIndex, cc.ColIndex] as GridTableCellStyleInfo;
	if (style.TableCellIdentity.Column != null &&
		style.TableCellIdentity.Column.MappingName == "ParentName" &&
		(style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell ||
		style.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell))
	{
		string newvalue = cc.Renderer.ControlText;
		GridRecordRow rr = style.TableCellIdentity.DisplayElement as GridRecordRow;

		rr.ParentRecord.SetValue("ParentDec", newvalue);
		e.TableControl.RefreshRange(GridRangeInfo.Row(cc.RowIndex));
	}
}
