There is a UI object on the page, how can I determine the mouse coordinates relative to this object on the PointerEntered event? My task is to display the resize cursor in the correct position. I kind of get the coordinates of the object and the mouse, but when, as I think, I move the mouse to 0: 0 and my object is there, the coordinates are different

My method

  private void Border_PointerEntered(object sender, PointerRoutedEventArgs e) { var border = sender as Border; var ct = (CompositeTransform)border.RenderTransform; var ttv = border.TransformToVisual(Window.Current.Content); var bordercoords = ttv.TransformPoint(new Point(0, 0)); var borderHeight = border.ActualHeight+ct.ScaleY; var borderWidth = border.ActualWidth+ct.ScaleX; var mouseAbsoluteCoords = Window.Current.CoreWindow.PointerPosition; if (bordercoords.Y -3>=mouseAbsoluteCoords.Y || mouseAbsoluteCoords.Y <= bordercoords.Y+3 && mouseAbsoluteCoords.X > bordercoords.X + 10 && mouseAbsoluteCoords.X < borderWidth - 10) { Window.Current.CoreWindow.PointerCursor = bottomTopCursor; } }

I try to cover the upper border with a check, I imagine it this way: when the cursor is in the blue zone, the necessary cursor is activated. Similarly for other areas

    Make an invisible element where it is marked in blue, and on it make the cursor change as needed when hovering. Then it is not necessary to calculate anything.

    • And if the red frame is a Grid`a cell, can I create more cells around it and the element is slightly shifted to the center? - SmiLe
    • If this is a table with cells that need to be resized, then there is a ready control. - Make Makeluv
    • No, this is a picture in the Grid with buttons in the top row and the size does not change the cells, but the entire Grid - SmiLe
    • one

    • It seems to be yes, but it is better to remove the overlay. - Make Makeluv
