Question

i have a question about property grid. when the form is shown i would like a group to be expand rather then collapsed. i have search a lot for that on the web and could not find it yet. any thoughts.

If you want to expand all items in the grid it is fairly simple. The property grid has a method for doing that:

propertyGrid.ExpandAllGridItems();

If it is a certain group you want to expand you can use this method:

private static void ExpandGroup(PropertyGrid propertyGrid, string groupName)
{
    GridItem root = propertyGrid.SelectedGridItem;
    //Get the parent
    while (root.Parent != null)
        root = root.Parent;

    if (root != null)
    {
        foreach (GridItem g in root.GridItems)
        {
            if (g.GridItemType == GridItemType.Category && g.Label == groupName)
            {
                g.Expanded = true;
                break;
            }
        }
    }
}
