Sorting,Filtering for unbound columns

[Andrew]

Hello guys. I've got unbound column, which is populated at grid_ItemDataBound handler

<telerik:GridBoundColumn UniqueName="ActivityCategories" HeaderText="Activity"/>


protected void grid_ItemDataBound(object sender, GridItemEventArgs e)
{
            if (e.Item is GridDataItem)
            {
                var item = (GridDataItem)e.Item;
                var templ = (SalesTemplate)item.DataItem;
                string activities = templ.ActivityCategories.Aggregate(String.Empty, (current, activity) => current + String.Format("{0},", activity.Name));
                item["ActivityCategories"].Text = activities.TrimEnd(',');
            }
 }

I would like add filtering,sorting functionality to this column. Standard SortExpression and filter doesn't help. What should I do?


Thanks, Andrew

Hello Andrew,

Currently enabling filtering and sorting functionality for the unbound columns in the RadGrid is not possible. As those columns do not contain data items the mentioned functionalities will not be applicable. 

All the best,

Hello, Maria

Is there any workaround over this?

Hello Andrew,

The best you can do is to manually "sort" the values and your databound column values and by using the header click for the unbound columns.
