You may want to prevent the end user from editing the data in particular cells. If you choose, you can lock individual grid cells from being edited at run time by using the FetchCellStyle event.

To lock the value in cell (1, 0), complete the following steps:

1. Set the FetchStyle property of the column containing the cell to True.

   In the Designer

   • Open the C1TrueDBGrid Designer. For information on how to access the C1TrueDBGrid Designer, see Accessing the C1TrueDBGrid Designer.
   • Select the First column by clicking on its column header in the right pane.
     Alternatively, it can also be selected from the drop-down list in the toolbar.
   • Click the Display Columns tab in the left pane.
   • Set the FetchStyle property to True.
   • Click OK to close the designer.

   In Code

   Add the following code to the Form_Load event:

   To write code in Visual Basic

   Visual Basic	Copy Code
   Me.C1TrueDBGrid1.Splits(0).DisplayColumns(0).FetchStyle = True

   To write code in C#

   C#	Copy Code
   this.c1TrueDBGrid1.Splits[0].DisplayColumns[0].FetchStyle = true;

2. Set the Locked property of the CellStyle object to True only for the value in row one:

   To write code in Visual Basic

   Visual Basic	Copy Code
   Private Sub C1TrueDBGrid1_FetchCellStyle(ByVal sender As Object, ByVal e As C1.Win.C1TrueDBGrid.FetchCellStyleEventArgs) Handles C1TrueDBGrid1.FetchCellStyle If e.Row = 1 Then e.CellStyle.Locked = True End If End Sub

   To write code in C#

   C#	Copy Code
   private void C1TrueDBGrid1_FetchCellStyle(object sender, C1.Win.C1TrueDBGrid.FetchCellStyleEventArgs e) { if (e.Row == 1) { e.CellStyle.Locked = true; } }

What You've Accomplished

The value in the cell (1, 0) cannot be edited:
