Question

I have 7 different ListViews.

There is a Sortmethod called SortClick(object sender, RoutedEventArgs e) –
when clicking on a GridViewColumnHeader, it raises the SortClick Event.

But in this method I must tell, which ListView should be Sorted, b.e

listview2.SortNow();

Now my Question is, how can I get the Control (ListView) from the GridViewColumnHeader (sender) or maybe the e, is that even possible?

How the ListView XAML looks like:

<ListView ItemsSource="{Binding MissingTables}" Name="missingTablesListView" HorizontalAlignment="Stretch" VerticalAlignment="Top" Margin="0" MinHeight="540" HorizontalContentAlignment="Stretch">
                    <ListView.Background>
                        <ImageBrush />
                    </ListView.Background>
                    <ListView.View>
                        <GridView>
                            <GridViewColumn DisplayMemberBinding="{Binding TableName}" Width="Auto">
                                <GridViewColumnHeader Click="SortClick" Content="TableName" Tag="TableName" ToolTip="Sortieren" />
                            </GridViewColumn>   
                            <GridViewColumn DisplayMemberBinding="{Binding Beschreibung}" Width="Auto">
                                <GridViewColumnHeader Click="SortClick" Content="Description" Tag="Beschreibung" ToolTip="Sortieren" />
                            </GridViewColumn>
                        </GridView>
                    </ListView.View>
                </ListView>

Here is the SortClick Code:

        /// <summary>
        /// Sortiert (Ascending/Descending)
        /// </summary>
        /// <param name="sender">sender</param>
        /// <param name="e">e</param>
        private void SortClick(object sender, RoutedEventArgs e)
        {       
            //ListView listView = sender as ListView;

            GridViewColumnHeader column = sender as GridViewColumnHeader;
            String field = column.Tag as String;

            if (currentSortColumn != null)
            {
                AdornerLayer.GetAdornerLayer(currentSortColumn).Remove(sorter);
                listView.Items.SortDescriptions.Clear();
            }

            ListSortDirection newDir = ListSortDirection.Ascending;
            if (currentSortColumn == column && sorter.Direction == newDir)
            {
                newDir = ListSortDirection.Descending;
            }

            currentSortColumn = column;
            sorter = new Sorter(currentSortColumn, newDir);
            AdornerLayer.GetAdornerLayer(currentSortColumn).Add(sorter);
            listView.Items.SortDescriptions.Add(new SortDescription(field, newDir));
        }

I’m not quite sure what you mean when you say SortClick Event, but i guess you mean the GridViewColumnHeader.Click event with your SortClick handler attached.

If you add the GridViewColumnHeader.Click to the ListViews like this:

<ListView GridViewColumnHeader.Click="SortClick">

you will get the ListView control in the sender argument of your event handler, and the GridViewColumnHeader in e.OriginalSource.

EDIT for clarity. In your SortClick handler, you’ll access the control like this:

ListView listView = sender as ListView;
GridViewColumnHeader header = e.OriginalSource as GridViewColumnHeader;
