[Solved] Selecting Row on Expand RowDetails

[Meehir]

Hi,

I am using radgridview having GridViewToggleRowDetailsColumn. The row details of particular row is depended on that.  So if I select that row and then expand, I get the row details using SelectedItem property of radgridview.
But, when I select particular row (second row) and expand another row (third row), the SelectedItem property of radgridview contains value of second row.  Hence , the row details of 3rd row gives the value of second row, which is incorrect. 

I need some way or property or event with which I can get value of third rowitem (the row which we do expand).

Kindly provide me the solution to this.

Thanks in Advance

Hello Meehir,

Firstly, you may use the RowDetailsVisibilityChanged event of the grid. It will be fired each time the RowDetails are collapsed/ expanded and you may get the corresponding row using the arguments.
Another approach may be to select the item on clicking on the Toggle Button:

this.clubsGrid.AddHandler(GridViewToggleButton.MouseLeftButtonDownEvent, new MouseButtonEventHandler(OnMouseDown), true);

private void OnMouseDown(object sender, MouseButtonEventArgs e)
{
    RadGridView grid = sender as RadGridView;
    var buttons = grid.ChildrenOfType<GridViewToggleButton>();
    foreach (GridViewToggleButton button in buttons)
    {
        if(button.IsPressed)
        {
            GridViewRow parentRow = button.ParentOfType<GridViewRow>();
            if (parentRow != null)
            {
                parentRow.IsSelected = true;
            }
        }
    }
}
