category bar double click

[Prashant]

the categories in property grid don't collapse - expand on double click .  You explicitly need to click on slider icon

Hello Prashant,

Thank you for contacting Telerik Support.

In order to expand/collapse the specific category on double click, it is necessary to subscribe to the ItemMouseDoubleClick event and revert the PropertyGridGroupItem.Expanded property:

public Form1()
{
    InitializeComponent();

    radPropertyGrid1.PropertySort = PropertySort.Categorized;
    radPropertyGrid1.SelectedObject = new Item(1234, "Custom title", "Description", 9834657);

    radPropertyGrid1.ItemMouseDoubleClick += radPropertyGrid1_ItemMouseDoubleClick;
}

private void radPropertyGrid1_ItemMouseDoubleClick(object sender, RadPropertyGridEventArgs e)
{
    PropertyGridGroupItem groupItem = e.Item as PropertyGridGroupItem;
    if (groupItem != null)
    {
        groupItem.Expanded = !groupItem.Expanded;
    }
}

public class Item
{
    [Category("Category1")]
    public int Id { get; set; }

    [Category("Category2")]
    public string Title { get; set; }

    [Category("Category2")]
    public string Description { get; set; }

    [Category("Category1")]
    public int BarCode { get; set; }

    public Item(int id, string title, string description, int barCode)
    {
        this.Id = id;
        this.Title = title;
        this.Description = description;
        this.BarCode = barCode;
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.

Thanks Desislava,

Just wondering, Shouldn't this be a default behavior of a PropertyGrid ? 

Like there is a default context menu, to category bar,  double click to expand collapse should be a default behavior as well.
Thats how it works in Visual Studio.  For TreeView nodes., Windows Explorer etc places where things can be expand and collapsed
