Use different add button icon for child's EditCommandColumn

[Dean]

Would it be possible to use a different icon for the EditCommand of children? In my attached screenshot, I would like the top level to stay the same with a "+" symbol, but I would like to replace the children icons with something else.

My idea so far is in the code behind, I would access the ItemCreated property of the RadTreeList and based on the DataItemIndex/HierarchyIndex, I would select a different icon.

How would I access the icon through the code behind?

Hi Eric, 

Please check the following forum thread which will show you how to get access to the icons of the child nodes (nested levels): How to remove Plus(Add) button from Child Nodes?, e.g.

protected void RadTreeList1_ItemDataBound(object sender, TreeListItemDataBoundEventArgs e)
{
    if (e.Item is TreeListDataItem)
    {
        var dataItem = (TreeListDataItem)e.Item;
        if (dataItem.HierarchyIndex.NestedLevel != 0)
        {
            //specify your edit column's UniqueName here
            dataItem["EditCommandColumn"].Controls[0] ...
        }
    }
}
