Hi,

Thank you for being patience. The following are the techniques to make the cell / column to be readonly.

Column:
You can set the ReadOnly property for the required column using the following code snippet.

>>>>> >>>
this.gridGroupingControl1.TableDescriptor.Columns[2].ReadOnly = true;
>>>>> >>>

Specific Cells:
This can be achieved by two techniques. You can check for the e.Style.CellValue and accordingly set the cell to be ReadOnly. Another way is by retrieving the record and accordingly making the cell to be read only. The following is the code snippet.
>>>>>>>>>
void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell || e.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell)
{
if (e.TableCellIdentity.Column.Name == "sno")
{
Element el = e.TableCellIdentity.DisplayElement;
if (el != null && el.Kind == DisplayElementKind.Record)
{
Record r = el.GetRecord();
object value = r.GetValue("sno");
int s = (int)value;
if (s == 2)
e.Style.ReadOnly = true;
}
}
}
}
