GridLength.Star Not Working For HorizontalAlignment="Center"

Question

Nathan Sokalski 4,056

I have a Grid as follows:

Note that all ColumnDefinition(s) have Width="*", which I would expect to make all columns the same width. However, this is giving me the following:

But if I change the Grid to HorizontalAlignment="Stretch" (instead of Center), I get the following:

Is there any way to center the Grid without wrapping it in another element (such as another Grid)? Thanks.

You defined too many columns, try to put only 2 ColumnDefinitions

That doesn't make any difference, even once I fill in all columns it does the same thing

Please try to add a width value for the Grid. If not, the grid will automatically resize the size of the element based on the size. If the value of HorizontalAlignment/VerticalAlignment is Stretch, the element will stretch to fill the available space in the grid cell. Please check this document: Layout panels.

That would be great if I knew or calculated the width of all the Children, however, doing this could be very tedious, especially for things such as borders & margins, or if the size of an element changes. Any other ideas?

If you don't want to set the width of it, then you might need to warp the grid with some elements.
