To hide a column on a C1List control, set the Visible property for the column to False either in the C1DisplayColumn Collection Editor or in code. To make a column visible, set the Visible property to True.

In the Designer

1. Open the Split Collection Editor in the Properties window by clicking the ellipsis button after the Splits property.
2. In the Split Collection Editor, click the ellipsis button next to the DisplayColumns property to open the C1DisplayColumn Collection Editor.
   
3. In the C1DisplayColumn Collection Editor, set the Visible property to False for the column that you would like hidden.
   

In Code

Add the following code to the Form_Load event:

To write code in Visual Basic

Me.C1List1.Splits(0).DisplayColumns.Item("UserCode").Visible = False

To write code in C#

this.c1List1.Splits[0].DisplayColumns["UserCode"].Visible = false;

This topic illustrates the following:

The final result will look like this, where the UserCode column is hidden.
