Hiding a Group Header When value is empty

[Jeff]

There are a couple of other posts related to hiding a Group Header but I believe this circumstance is a bit different.

 

We have a hierarchical Grid with the following levels:

Track > Course > Lesson

 

The Lessons within a course are then grouped by Chapters. But some of the courses have no chapters - just a series of lessons. In those cases we want to hide the group header. It is not a case where there are no items, it is just that the related chapter grouping is "null".

Is there a way to check that if the group value that is returned is "null" (or a specific value if that is easier) and then hide the group header and expand/collapse button if that is the case?

thanks

Hello Jeff,

You can try out the following example to hide the GroupHeaderItem when it displays no value:
c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridGroupHeaderItem)
        {
            GridGroupHeaderItem gpHeader = e.Item as GridGroupHeaderItem;
            if(gpHeader.DataCell.Text.Substring(gpHeader.DataCell.Text.IndexOf(":") + 1) == " ")
            {
                gpHeader.Display = false;
            }
        }
    }

Thanks
Princy.
