Hi, please see images below and let me know if this is something that has been mentioned before.
When we first load our grid none of the columns are shown - see first screenshot (a).
After repopulating the dataset (ObservableCollection) with data, the columns are still all shrunk/collapsed - second image (b).
The blue column size stretcher has to be dragged to the right to reveal all the columns - third image (c).
It looks like it may be due to the container, Grid being set to * Width as we want the grid to fully populate the right of the screen, is there a way round this to have the radgridview work in this manner?
