Open Filtering Control Code behind

[metealika]

Hi,
How can i open the filtering control popup for a given column code behind?

For example,
private void ShowFilteringControl(GridViewDataColumn column)
{
    myFilteringControl = new ????;
    myFilteringControl.Show();
}

or, something like that?

Thanks.

Hi,

The FilteringControl is a Popup and it is shown on the screen over RadGridView control. GridViewColumns do not expose a method to open the filtering control from code behind instead of waiting for a user interaction.

You can still find the instance of the specific Popup and try implementing any modifications yourself.

For example:

private void grid_Loaded_1(object sender, RoutedEventArgs e)
{
    this.Dispatcher.BeginInvoke(new Action(() => this.FindPopups()));
}

private void FindPopups()
{
    foreach (var headerCell in this.myGrid.ChildrenOfType<GridViewHeaderCell>())
    {
        var popUp = headerCell.ChildrenOfType<Popup>().FirstOrDefault();

       // do any modification on the Popup itself
    }
}

Hi,

On a side note, you can also try the following approach by finding the respective FilteringDropDown element and setting its property IsDropDownOpened to True:

private void Button1_Click(object sender, RoutedEventArgs e)
{
    clubsGrid.ChildrenOfType<FilteringDropDown>().First().IsDropDownOpen = true;
}
