How to get a Grid column width in pixels in WPF?

Question

列宽以不同方式指定（星形，自动等）如何获取特定列的宽度（以像素为单位）？

GridLength l=tip.basis.ColumnDefinitions[0].Width;

Answer 1

You can use the ActualWidth or ActualHeight property of elements to get the width/height of elements. This answer describes the difference between `'ActualWidth' and 'Width'.

So in the above example it would be:

Double width = tip.basis.ColumnDefinitions[0].ActualWidth;

And also keep in mind that WPF uses Device Independent Pixels, as described in this answer .

Answer 2

The ActualWidth property should provide the width of the column in Pixels

Answer 3

Use the ActualWidth property to get the width. It represents

The width of the column in device-independent units (1/96th inch per unit).
