Examples

The following code example demonstrates using the HitTest method to determine the location of a mouse event in a ListView. To run this example, paste it into a Windows Form that contains a ListView named listView1 that is populated with items. Associate the MouseDown event for listView1 with the listView1_MouseDown method in this example.

void HandleMouseDown(object sender, MouseEventArgs e)
{
    ListViewHitTestInfo info = listView1.HitTest(e.X, e.Y);
    MessageBox.Show(info.Location.ToString());
}

Private Sub HandleMouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) _
        Handles Me.MouseDown, listView1.MouseDown

    Dim info As ListViewHitTestInfo = listView1.HitTest(e.X, e.Y)
    MessageBox.Show(info.Location.ToString())

End Sub

Remarks

Use this method to determine whether a point is in an item or subitem, and where in the item the point is located, such as on the label or image area. If the coordinates are located outside the control, the returned ListViewHitTestInfo object has a Location property of "None"; and the Item and SubItem properties are set to null.
