Hi,
Thank you for your interest in Syncfusion product.
If you want to set the ReadOnly cell in GridControl,then please try using QueryCellStyleInfo event in GridControl to achive this behaviour.
Please refer the code below:
Private flag As Boolean = True
Private Sub gridControl1_QueryCellInfo(ByVal sender As Object, ByVal e As GridQueryCellInfoEventArgs)
If e.RowIndex = 1 AndAlso e.ColIndex = 1 Then
If flag Then
e.Style.ReadOnly = True
Else
e.Style.ReadOnly = False
End If
End If
End Sub
Refer the sample in below link:

Lingaraj S.
