WinForms Data Grid - Create custom columns

This example demonstrates how to create a custom grid column.

Create a GridColumn descendant class. If you add properties to a custom column and want to serialize them (using the SaveLayoutTo... method), apply the XtraSerializableProperty attribute.

C#
public class MyGridColumn : GridColumn {  
    public MyGridColumn() { }  
    string customDataValue = string.Empty;  

    [XtraSerializableProperty()]  
    public string CustomData {  
        get { return customDataValue; }  
        set { customDataValue = value; }  
    }  
    protected override void Assign(GridColumn column) {  
        base.Assign(column);  
        if(column is MyGridColumn) {  
            this.CustomData = ((MyGridColumn)column).CustomData;  
        }  
    }  
}

Create a descendant from the GridColumnCollection class and override the CreateColumn method to instantiate a custom column:

C#
public class MyGridColumnCollection : GridColumnCollection {  
    public MyGridColumnCollection(ColumnView view) : base(view) { }  
    protected override GridColumn CreateColumn() {  
        return new MyGridColumn();  
    }  
}

Create a descendant from the GridView class and override the CreateColumnCollection method to instantiate your column collection:

C#
public class MyGridView : DevExpress.XtraGrid.Views.Grid.GridView {  
  public MyGridView() : this(null) {}  
  public MyGridView(DevExpress.XtraGrid.GridControl grid) : base(grid) {  
    // Your initialization code.  
  }  
  protected override string ViewName { get { return "MyGridView"; } }  
  protected override GridColumnCollection CreateColumnCollection() {  
    return new MyGridColumnCollection(this);  
  }  
}
