Basic Grid help (hiding cols bolding cols)

[Craig Glencross]

If I have a GridGroup and have assigned a dataset to it how can I hide and unhide rows?

Also when I doubleclick on a row the DoubleClick event does not fire. Do I have to set some setting to allow for this?

Finally how can I find what row is selected and what cell of that row is selected?

Thanks.

With grdMain
.ResetAppearance()
.DataSource = dv
.TableDescriptor.AllowNew = False
.TableDescriptor.AllowEdit = False
.TopLevelGroupOptions.ShowCaption = False
.TopLevelGroupOptions.ShowColumnHeaders = True
end with

Hi, Issue 1:Hide/Show a row Could you try this code to hide/show a row in grouping grid.Here is a code snippet. //For hide the 5 th row this.gridGroupingControl1.TableControl.Model.Rows.Hidden[5] = true; //For show the 5 th row this.gridGroupingControl1.TableControl.Model.Rows.Hidden[5] = false; Issue 2:Double click You need to handle the TableControlCurrentCellControlDoubleClick event to catch double click on a cell in grouping grid.try this code private void gridGroupingControl1_TableControlCurrentCellControlDoubleClick(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlControlEventArgs e) { System.Diagnostics.Trace.WriteLine("Double Clcik fired"); } Issue 3: Selection By default, clicking a cell does not select it (ie. add it to the grid.TableControl.Model.Selections collection). But clicking a cell does fire the event to clear any selections if they were present. So, that is why you did not see any CurrentCell rowIndex/ColIndex in SelectionChanged Event If you want to the currentcell to be treated as a selection (& added to the grid.TableControl.Model.Selections collection), then you can set thegridGroupingControl1.TableControl.Model.Options.ExcelLikeCurrentCell = true. This will always make the currentcell be selected.

//to set the ExcelLikeCurrentCell Selection
gridGroupingControl1.TableControl.Model.Options.ExcelLikeCurrentCell = true;
private void TableModel_SelectionChanged(object sender, GridSelectionChangedEventArgs e)
{
	if(e.Reason == GridSelectionReason.SetCurrentCell ) 
	{
		GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
		Console.WriteLine("Selected (row, column) = ("+ cc.RowIndex + ", " + cc.ColIndex + ")" ) ;
	}
}

Here is a sample for implementing it. SelectionTypes_CS.zip Please refer to the KnowledgeBase link below for more details http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=344 Let me know if this helps. Thanks for choosing Syncfusion Products. Regards, Haneef
