[RESOLVED] How to get Top position of LV contained in TLP in SplitContainer

[BruceG]

Hello all,
For years I have been using the technique to simulate an "editable listview", where on MouseUp, depending on which subitem is clicked, I float a textbox or combobox on that "cell", and the user can then "edit" that cell. Apparently I have always done this where the ListView is placed directly on the form, and did not have a problem with the float positioning.

Now I had to modify such a form where the ListView is now contained (docked) within the second row of a TableLayoutPanel, which itself is docked in the second (bottom) panel of a SplitContainer.

So now of course when my ListView MouseUp routine refers to "ListView1.Top" and "ListView1.Left", those positional values are relative to the container, which in this case is in the second row of the TLP, which again is contained within the bottom panel of the SplitContainer. (So obviously my floating textbox or combobox pops up in the wrong place.)

What would be the proper syntax to add the correct displacement to "ListView1.Top" and "ListView1.Left" so that I get its "absolute" top and left positions relative to the form itself? I know I need to add "SplitContainer1.Panel2.Top", but it appears that adding the right values for the TLP is a little trickier.

Any and all help appreciated ...

Firstly, why not just use a DataGridView instead of a ListView? That way you do not have to simulate anything.

As for the question, you can use a control's PointToScreen and PointToClient methods to translate coordinates between frames of reference. For instance, this:

Dim tb As New TextBox

tb.Location = Me.PointToClient(ListView1.PointToScreen(Point.Empty))
Me.Controls.Add(tb)

is going to place the new TextBox at the same location as ListView1 no matter what the hierarchy of controls is.

Thanks, jmcilhinney, I was able to implement your suggestion.
Old code:

           ClickedItem.Y += Me.lvwOrderItems.Top
           ClickedItem.X += Me.lvwOrderItems.Left

New code:

            Dim objLVLoc As Drawing.Point
            objLVLoc = Me.PointToClient(lvwOrderItems.PointToScreen(Point.Empty))
            ClickedItem.Y += objLVLoc.Y
            ClickedItem.X += objLVLoc.X
