RadGridView and sort

[Volle Bertrand]

Hello,

I would like to remove the sort when clicking on a column header and develop my own context menu which contains a "sort" item calling the telerik sort methods.

The only way I found to remove the sort with the header consists in setting to false the property EnableSorting. But if I do this the sorting method of the API doesn't work anymore.

Can you help me?

Thanks

Hi Volle Bertrand,

Thank you for contacting us.

You can disable the sorting in grid header cells by using custom cells. They should inherit from GridHeaderCellElement. You should also override OnMouseUp event to intercept mouse messages. Here is a sample:

void radGridView1_CreateCell(object sender, GridViewCreateCellEventArgs e)
{
    if (e.CellType == typeof(GridHeaderCellElement))
    {
        e.CellType = typeof(MyHeaderCell);
    }
}

public class MyHeaderCell : GridHeaderCellElement
{
    public MyHeaderCell(GridViewColumn column, GridRowElement row)
        : base(column, row)
    { }

    protected override Type ThemeEffectiveType
    {
        get { return typeof(GridHeaderCellElement); }
    }

    protected override void OnMouseUp(MouseEventArgs e)
    {
        //base.OnMouseUp(e);
    }
}

Please handle ContextMenuOpening event to replace the default sorting action:

void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    if (e.ContextMenuProvider is MyHeaderCell)
    {
        for (int i = 0; i < 3; i++)
        {
            e.ContextMenu.Items.RemoveAt(0);
        }
        e.ContextMenu.Items.Insert(0, new RadMenuItem("Custom sort"));
    }
}

I hope this helps. If you have more questions, I will be glad to assist you.
