Custom Items and Grouping

[Hunter]

Hello, I went through and created a custom visual item for my listview and everything worked out great (Telerik documentation was a big help). I then tried to apply custom grouping to my listview and no grouping appeard (everything loads, just without groups). After another quick look I realized that my custom item is also being applied to the group item (doh!). How would I go about determining the type of item being created int the VisualItemCreating event? Thanks

Hello Hunter,

Thank you for writing.

The event arguments of the VisualItemCreating event contain the original visual item that will be used if you do not replace it. You can test its type to determine whether it is a group item or a regular item. The following code snippet demonstrates this:

void radListView1_VisualItemCreating(object sender, ListViewVisualItemCreatingEventArgs e)
{
    if (e.VisualItem is BaseListViewGroupVisualItem)
    {
        //creating group
    }
    else
    {
        //creating item
    }
}

I hope this will help you. Should you have any additional questions, do not hesitate to contact us.

All the best,
Ivan Todorov
