Listview DblClick in which column

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm using the Codejock-Listview-Control with the report view (xtpListViewReport). In the listview there are ListviewItems with some ListviewSubItems.
I use the doubleclick-event to know which item and in which column was doubleclicked.

The DblClick-event is also fired if it is clicked in the area without items. So I can't use the SelectedItem-property to check which item is doubleclicked.

This behaviour I solved with the Hittest-method. This works also if it's vertically scrolled.

To check in which column was clicked, I calc the column-width - see the code. But if there is horizontally scrolled, the result is wrong.

Question: How Can I detect the horizontally scroll-offset?

private void cjListView_DblClick(object sender, EventArgs e)
{
            int f = 16; // it's necessary for a correct result
            XtremeSuiteControls.ListViewItem lvi = cjListView.HitTest((float)currentmouse_x * f, (float)(currentmouse_y - cjListView.Margin.Top) * f);

            if (lvi == null)
            {
                // DblClick was not on a ListViewItem
                return;
            }

	     // get the clicked column
            int x_coordinate= cjListView.Margin.Left;
            int selected_col = 0;
            for (int i = 1; i < cjListView.ColumnHeaders.Count + 1; i++)
            {
                x_coordinate += cjListView.ColumnHeaders.Width;
                if (x_coordinate > currentmouse_x)
                {
                    selected_col = i;
                    break;
                }
            }
			MessageBox.Show("Hittest: " + lvi.Text + Environment.NewLine + "Column: " + selected_col.ToString());

}

private void cjListView_MouseUpEvent(object sender, AxXtremeSuiteControls._DListViewEvents_MouseUpEvent e)
        {
            currentmouse_x = e.x;
            currentmouse_y = e.y;
        }
