I assume your ListBox is databound to some source collection? If this is the case, the DataContext of your button will be an instance of one of your bound items. You can then do as follows:

// if for example you bind a list of MyDataObject instances ...

// create a list
List<MyDataObject> myDataObjects = CreateTestData();

// bind it
listBox1.ItemSource = myDataObjects;

...

// in your click handler
private void btnDeleteDashboard_Click(object sender, EventArgs args)
{
  // cast the sender to a button
  Button button = sender as Button;

  // find the item that is the datacontext for this button
  MyDataObject dataObject = button.DataContent as MyDataObject;

  // get the index
  int index = myDataObjects.IndexOf(dataObject);
}
