Hello everyone,

I am trying to use a datagrid that's bound to a CollectionviewSource, I could group items as follows :

C#

ICollectionView CV = CollectionViewSources.GetDefaultView(datagridItems.itemssource);
CV.GroupDescriptions.Add(new PropertyGroupDescription("Level"));

the thing is I didn't know how to remove the group using the CV.GroupDesciptions.Remove().

Thank you previously.

You either need to find the item you want to remove:

C#

var itemToRemove = CV.GroupDescriptions
    .OfType<PropertyGroupDescription>()
    .FirstOrDefault(pgd => pgd.PropertyName == "Level");

if (itemToRemove != null) 
{
    CV.GroupDescriptions.Remove(itemToRemove);
}

or find its index and use RemoveAt:

C#

for (int index = 0; index < CV.GroupDescriptions.Count; index++)
{
    var pgd = CV.GroupDescriptions[index] as PropertyGroupDescription;
    if (pgd != null && pgd.PropertyName == "Level")
    {
        CV.GroupDescriptions.RemoveAt(index);
        break;
    }
}
