My problem sounds simple, but unfortunately it's not.
I have a DataGrid with 23 columns, each of them has MinWidth set to some value, Width = "Auto" . One of the columns has Width = "*", because it's the name of the object and has to fit the content (it does not work now).
When the window is loaded, I'm not able to resize the columns manually. It works only, when I resize all columns automatically before by doubleclicking (like in excel) the columns.
Additionally, when the window is loaded, the MinWidth property of "Name" does not work, the column is much smaller than 100, and does not fit to the content (the Name has +/- 150 chars).
When I change the Width to "Auto", then I'm able to resize the columns manually, but it's still not behave as expected.
I've tried to set the MinWidth of the grid to a big value - the resizing worked, but as expected, the grid has not been visible at all and the HorizontalScrollbal has not been visible.
I couldn't find any other possible solutions.
Below is the code which I'm using:
