How to hide the top row on pivot grid control which says Drop Filter Fields here
We found that this cannot be achieved directly in our control. However this can be achieved by adding the following lines.
C#
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
this.pivotGrid1.GroupingBar.FilterHeaderArea.Visibility = System.Windows.Visibility.Collapsed;
this.pivotGrid1.GroupingBar.FilterHeaderArea.BorderBrush = Brushes. Transparent;
var parent = VisualTreeHelper.GetParent (this.pivotGrid1.GroupingBar.FilterHeaderArea) as Grid;
parent.Height = 35d;
parent.RowDefinitions [0].Height = new GridLength (0d);
parent.VerticalAlignment = VerticalAlignment.Bottom;
this.pivotGrid1.Margin = new Thickness (0, -37, 0, 0);
}
