Hi,
I have a GridListControl with single selection mode.
I need to lock selection change.
Please Help.

Hi Dmitry,
You can lock the selection change by using SelectionChanging Event handler in the GridListControl. Here is the code snippet.

		private void Grid_SelectionChanging(object sender, GridSelectionChangingEventArgs e)
		{
			e.Cancel = true;			
		}
		private void gridControl1_CurrentCellShowingDropDown(object sender, Syncfusion.Windows.Forms.Grid.GridCurrentCellShowingDropDownEventArgs e)
		{
			GridCurrentCell cc = this.gridControl1.CurrentCell;
			GridDropDownGridListControlCellRenderer cr = cc.Renderer as GridDropDownGridListControlCellRenderer;							
			this.gridControl1[3,3].ReadOnly = true;
			cr.ListControlPart.Grid.SelectionChanging +=new GridSelectionChangingEventHandler(Grid_SelectionChanging);
		}

Refer to the sample for more details.

Let us know if you need further assistance,

Hi Dmitry,

Check if cc.EndEdit() in CurrentCellShowingDropDown event, solves for you.

Thanks,

Hi Dmitry,

Please try this.

this.gridListControl1.Grid.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(Grid_PrepareViewStyleInfo);

GridCurrentCell cc;
private void Grid_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
cc = this.gridListControl1.Grid.CurrentCell;
if(cc.HasCurrentCellAt(e.RowIndex))
{
e.Style.Borders.Top = new GridBorder(GridBorderStyle.Standard);
e.Style.Borders.Bottom = new GridBorder(GridBorderStyle.Standard);
e.Style.Borders.Left = new GridBorder(GridBorderStyle.Standard);
e.Style.Borders.Right = new GridBorder(GridBorderStyle.Standard);
}
}

Best regards,
Stanley

Thanks for quick your answers.
Sorry again for my English.

I have two GridListControls - Grid1(Master) and Grid2(Detail). I use SetDataBinding for binding with source(IBindingList).
I need:
if mode == Modes.Edit then
1. Cursor(SelectedItem) in Grid1 is fixed.
2. When I try change SelectedItem (mouse click) in Grid1, data in Grid2 be fixed to.

if mode == Modes.View then Cursor in Grid1 is free.

When I use your last variant I get one selected item.
But if I click on other item my Grid2 has data change.

Hi Dimtry,

Setting this.gridListControl1.Enabled = false; will avoid the user from changing the selection, and again setting this.gridListControl1.Enabled = true; will allow the user to select.
