How to prevent SelectedItems to keep selecting order ?

[Thomas LEBRUN]

Hi,

Currently, the SelectedItems property keep the selecting order for the items selected. For example, if I have a grid with the row A, B, C and D and if I select D, A and C,  the SelectedItems propery will contain D, A, and C (in this order, even if it's not how they are displayed).

Is it possible to know the selected items but with the order of how they are in the source ? (so, in my example, it will be A, C, D) ?

I hope to be clear :)


Thanks !

Hello Thomas LEBRUN,

You could get the selected items in the order they appear in RadGridView by using the following method :

private IEnumerable<Object> GetSelectedItems(RadGridView gridView)
{
        List<object> selectedItems = new List<object>();

        for (int i = 0; i < gridView.Items.Count; i++)
        {
            if (gridView.SelectedItems.Contains(gridView.Items[i]))
                selectedItems.Add(gridView.Items[i]);
        }

        return selectedItems;
    }
}

We should probably include this method or a similar one in our public extensions method so that people can use it out of the box.

Hi,

I have been facing similar kind of issue as mentioned in above post.

Do you have the functionality added in any of new releases of telerik after this?

Hello,

The order of the items in the SelectedItems collection is by the way they have been selected. 
There is not a property to return the selected items ordered in the same way as they are displayed in the GridView.

Hello,

Any update on this? We would like to get the selected items in the order currently displayed in the grid. I tried the "GetSelectedItems" method above from 12/2009 but the performance is only good when item count is low. With 14K items this loop locks the UI for a few seconds (I imagine from the Contains() method), some of our grids have 90k+ items, so this solution doesn't work for us.

Is there a better way I am missing?

Thank you,

Patrick

Hello Patrick,

At this moment I can't give any other approach which you can use. With the current implementation of the RadGridView, the SelectedItems collection will contain items in the order they are selected.
