How to change the sorting options to two and keep the sorting status automatically

[Zhiyong]

Currently there are three sorting options, descending, ascending and no sorting. Could I limit to descending and ascending.

Also, everytime when a column is activated, the first sorting action is always ascending, is it possible to make it remember the last sorting status? If necessary, I can also write some code to keep track of the sorting state.

Thanks!

Hi Zhiyong,

 
There is no problem to set the sorting order only to Ascending and Descending. What you need to do is just to handle the Sorting event of the grid and skip the none-sorting state. For example:

void playersGrid_Sorting(object sender, GridViewSortingEventArgs e)
{
    if (e.NewSortingState == SortingState.None)
    {
        e.NewSortingState = SortingState.Ascending;
    }
}

As for saving the last sorting state, you may use the method demonstrated in our online documentation and shown in our demos.

Thanks! The setting document seems a little bit overwhelming.

Do you mean I should simplely store the setting when they lost focus and restore sorting setting first at void playersGrid_Sorting(object sender, GridViewSortingEventArgs e), then do the reverse?

Best,

Hi Zhiyong,

Mainly, the idea explained in our online documentation is to show how to save the settings of the grid whenever it is unloaded/closed and to present that same grid with the same sorted/filtered/grouped state whenever it is loaded again. For saving those settings an Isolated Storage is used. In case you require to preserve only the Sorting settings, you may implement only the lines of the code corresponding to them. 
As you can see in our demos, if you sort the grid, go to another example and them come back to the Save & Load Settings example, you will prove that the grid is in the same sorted state as you have left it.
In case you have some specific requirements considering the Save & Load Settings functionality, we would need more details about your scenario in order to provide you with an appropriate solution.
