WPF drag item from listbox and drop in textbox - wpf

I'm trying to drag an item from a listbox to a textbox in WPF.
I can't get any code that will let me do this.
Thanks


Use selection change event of listbox
private void listBox2_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
ListBoxItem i = (ListBoxItem)listBox2.Items[listBox2.SelectedIndex];
s = i.Content.ToString();
DragDrop.DoDragDrop(listBox2, i.Content.ToString(), DragDropEffects.All);
}

Telerik gridview to check for row dirty

How can we know if a row is dirty in a telerik gridview?
In datagridview we had IsCurrentRowDirty property.
Is there any such property in Telerik?

One way to do this with RadGridView is to use the CellValueChanged event:
void radGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
{
e.Row.Tag = "ThisRowIsDirty";
}

How do you access Expander content dynamically?

I have multiple dynamic generated Expanders having DataGrid as Content, and CheckBoxes in DataGrid. I got the DataGrid with the following code below but don't know how to get the Expander.
private void ChkBoxDamage_Checked(object sender, RoutedEventArgs e)
{
CheckBox b = (CheckBox)e.Source;
DataGridRow row = b.TemplatedParent.TryFindParent<DataGridRow>();
row.Background = System.Windows.Media.Brushes.Red;
DataGrid dataGrid = b.TemplatedParent.TryFindParent<DataGrid>();
Expander Gridexpanderr = dataGrid.TemplatedParent.TryFindParent<Expander>();
Gridexpanderr.Background = new SolidColorBrush(Colors.Red);
}
The above code won't change expander Background Color.

ListView Expander issue in wpf

I am using a checkbox on expander. I want, when I check that checkbox ,it will select all rows of list view those are coming under that expander.

set the listview's selectionmode to Multiple' or 'Extended and
on the CheckBox_Checked event you can write the code to select the rows of listview
private void CheckBox_Checked(object sender, RoutedEventArgs e)
{
listview1.SelectAll();
}

Try this inside your checkbox_click events handler:
listView1.BeginUpdate();
foreach (ListViewItem i in listView1.Items)
{
i.Selected = true;
}
listView1.EndUpdate();
Which gives you a bit more flexibility.
