The <b>ExtendedProperties</b> property of a System.Data.DataColumn is just an object of type <b>System.Data.PropertyCollection</b>, which is just a Hashtable.

So you can just put a Hashtable in the Tag property of the Xceed.Grid.Column (or any GridElement). Here’s a class that helps using the Tag property as ExtendedProperties (warning: untested code):<code>
using System;
using System.Collections;
using Xceed.Grid;
public class ExtendedProperties
{
public static Hashtable Get(GridElement element)
{
Hashtable h = element.Tag as Hashtable;
if (h == null)
{
h = new Hashtable();
element.Tag = h;
}
return h;
}

public static object Get(GridElement element, object key)
{
return Get(element)[key];
}

public static void Set(GridElement element, object key, object value)
{
Get(element)[key] = value;
}
}</code>You can use it like this:<code>object prop = ExtendedProperties.Get(Grid1.Columns[Index], “key”);
ExtendedProperties.Set(Grid1.Columns[Index], “key”, “newvalue”);
Hashtable allProperties = ExtendedProperties.Get(Grid1.Columns[Index]);</code>
