To freeze columns in the grid, set the Frozen property to True. Freezing columns locks them from being scrolled and also prevents all columns with a lesser index from being scrolled. This property can be set either in the designer or in code.

In the Designer

1. Open the C1TrueDBGrid Designer.
2. In the designer, select the Last column by clicking it in the right pane.
   The column can also be selected by choosing Last from the drop-down list in the toolbar.
3. Click the Display Column tab in the left pane.
4. Locate the Frozen property and set it to True.
5. Click OK to close the designer.

In Code

Add the following code to the Form_Load event to freeze the Last column:

c1TrueDBGrid1.Splits[0].DisplayColumns[2].Frozen = true;

c1TrueDBGrid1.Splits[0].DisplayColumns[2].Frozen = true;
