Is there a way to check the x and y coordinates of a label in debug view?

As asked, the method depends on whether the Label is a server-side ASP.NET control (rendered HTML in the browser) or a desktop VB.NET WinForms control. As suggested, runtime inspection helps, but the exact properties and meaning differ. The tips below show what to check and how to get coordinates you can rely on.

For WinForms (VB.NET) the control exposes Location, Left/Top, and Bounds (all relative to the parent). To get absolute screen coordinates use PointToScreen, and to get coordinates relative to the form convert back with PointToClient:

' WinForms: positions in pixels
Dim clientPt As Point = Label1.Location        ' relative to parent
Dim bounds As Rectangle = Label1.Bounds
Dim screenPt As Point = Label1.PointToScreen(New Point(0, 0)) ' top-left on screen
Dim formPt As Point = Me.PointToClient(screenPt)              ' top-left relative to form
Debug.WriteLine(String.Format("client ({0},{1}) screen ({2},{3}) form ({4},{5})",
                              clientPt.X, clientPt.Y, screenPt.X, screenPt.Y, formPt.X, formPt.Y))

For ASP.NET (web) the server Label does not carry X/Y; layout is decided by the browser. Use client-side JavaScript or the browser DevTools (F12) to read the DOM position. getBoundingClientRect() gives viewport coordinates; add scroll offsets for document coordinates:

// client-side (browser)
var el = document.getElementById('<%= Label1.ClientID %>');
var rect = el.getBoundingClientRect(); // left/top relative to viewport
console.log('viewport left/top:', rect.left, rect.top);
console.log('document left/top:', rect.left + window.scrollX, rect.top + window.scrollY);

Note: values are pixels; parent containers, CSS margins, transforms, and scrolling change the reported coordinates. For nested controls, always confirm whether the value is relative to parent, form, viewport, or screen before using it.

you can use the immediate pane and messagebox or debug.print them
