Hi,
I am facing one problem.I am using RowDetailstemplate to show nested data.....working fine..
But when I expand the some other row  it need Collapse previous expanded row.
I want show expanded row one at a time.

Is there any way to achieve the functionality.It is help full if you provide sample solution..............

This will accomplish what you're trying to do:

            

//The logic in this if statement will close the previously open GridRowDetails selection
            if (e.Visibility == System.Windows.Visibility.Visible)
            {
                if (lastExpandedRow != null)
                {
                    lastExpandedRow.DetailsVisibility = System.Windows.Visibility.Collapsed;
                }

                lastExpandedRow = e.Row;
            }

Hi,

Yes, that is a perfect solution.

Another approach would be to use the GridViewToggleRowDetailsColumn which has a property called ExpandMode which does exactly what you want. Simply set it to Single and you will have only one row detail expanded at a time.
