    I have a RadGridView in my application. Currently, this RadGridView is allowing users to sort by multiple columns. However, I do not want mult-sort enabled. However, it appears that it is enabled by default.

    1. Is multi-sort enabled by default?
    2. If so, how do I disable multi-sort?
    3. If not, what properties are associated with sorting? I just want to sort by one column at a time.

    Thank you,

    Hi Frustrated Dev,

    The CanUserSortColumns property is used to allow or disallow sorting from the UI and this property is set to true by default. For the time being there is no distinction between multiple and single sorting and if sorting is enabled, multiple sorting is enabled as well. Luckily you can disable multiple sorting with just a few lines of code:

    public MainPage()
        this.playersGrid.ItemsSource = Club.GetPlayers();
        // true by default
        this.playersGrid.CanUserSortColumns = true;
        this.playersGrid.Sorting += new System.EventHandler<GridViewSortingEventArgs>(playersGrid_Sorting);
    void playersGrid_Sorting(object sender, GridViewSortingEventArgs e)
        if (this.playersGrid.SortDescriptors.Count >= 1 && 
            this.playersGrid.SortDescriptors[0].Member != e.SortPropertyName)
            // if grid is already sorted - cancel pending sort request
            e.NewSortingState = SortingState.None;
            e.Cancel = true;

    Hope this helps.

    All the best,
    the Telerik team
