Restrict the editing of specific cell

To restrict the cells from editing only in specific scenarios like using dynamic filter with expressions (GridDynamicFilter), make use of the QueryCellStyleInfo event and validate the condition that ReadOnly property should be false only if it is FilterBar CellType.

C#

void hierarchyGrid_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
     //stop user from editing the contents of the grid cell
     e.Style.ReadOnly = (e.TableCellIdentity.TableCellType == GridTableCellType.FilterBarCell)? false : true; 
}

VB

Private Sub hierarchyGrid_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs)
     'stop user from editing the contents of the grid cell
     e.Style.ReadOnly = If((e.TableCellIdentity.TableCellType = GridTableCellType.FilterBarCell), False, True)
End Sub
