WPF DataGridColumn won't let me set ".width = double.NaN" for auto-sizing columns. "Value should not be infinity" error?

I have a WPF DataGrid and I am setting up columns manually in code behind. I am trying to set the column size to Auto with the following code:

customBoundColumn.Width = double.NaN;

But then at run-time I get the following error:

Value should not be infinity. Parameter name: value

I read in many places that double.NaN is what is used to set the column size to auto. What am I doing wrong?

P.S. customBoundColumn is an instance of DataGridBoundColumn

Solution

  • I believe you can simply use DataGridLength.Auto to set your width back to Auto

    customBoundColumn.Width = DataGridLength.Auto;
