  Hello,

  I found a minor issue with column 0 failing to draw in a very specific circumstance. I am reporting this because it took me a while to find the source of the problem.

  If you set C1FlexGrid1.Cols.Fixed = 0 after setting DataSource, and the grid is narrow enough that it requires a horizontal scroll bar, the first column fails to render until you trigger a redraw by adjusting size or scrolling.

  You can see the issue in the attached zip and pressing the ‘Fill Data’ button. The small form size is intentional and necessary to see the issue. Additionally, setting C1FlexGrid1.Cols.Fixed = 0 before setting DataSource works correctly.

  Hi,

  I could not observe the issue you described. The first column is rendered correctly without triggering redraw. See attached video to see my observation.

  Do you observe this issue consistently? Also, please mention the version of FlexGrid you’re using so I can check it with that version.
