By default users can interact and edit the grid and columns in the grid. If you choose, you can set the grid or specific columns in the grid to not be editable with the IsReadOnly property.

In XAML

To lock the grid from being edited, add IsReadOnly="True" to the <c1:C1DataGrid> tag so that it appears similar to the following:

<c1:C1DataGrid x:Name="C1DataGrid1" IsReadOnly="True">

In Code

To lock the grid from editing, set the IsReadOnly property to True. For example:

Me.C1DataGrid1.IsReadOnly = True

this.c1DataGrid1.IsReadOnly = true;
