Column widths in a DataGridView

Question

Hi

I have a requirement to have a DataGridView come up with the columns stretched across the view as if AutoSizeColumnsMode = Fill, but then after the GUI is up allow the user to resize the columns.  On resizing one column, the size of all other columns should not be affected.  If the total width becomes too large, the horizontal scrollbar should appear.

We've tried manually setting the sizes of the columns, but on my coworker's screen the columns are too large -- several are not visible and the scroll bar appears.  When he sets the size, the columns come up short on my screen, leaving a gray area on the gridview.  Neither is acceptable to QA.

I've tried also setting AutoSizeColumnsMode = Fill, then unsetting it, but the columns snap back down to a small size.  After that we've gotten really hacky doing math to fill in the column widths.

I would think this is a really common problem with a standard solution, but cannot find anything the internet.  Is there a suggested way to handle this situation?

Thanks

yes.

To get rid of gray area of dgv, you can set the background color of dgv to the same as its your form.

But I asctually still dont know what really is your problem. Why you want to allow user to resize columns width? I wouldn`t do that.

Because that is the requirement handed down from on high (that is, it is a customer request).

Hi James,

How’s it going now? Do you have any updates about the previous issue?

What I ended up doing was setting AutoSizeColumnsMode = Fill to start, then before making the form visible I did some math to figure out the column widths, set AutoSizeColumnsMode = None, and set the sizes of each column.

Hacky, but it works (and QA is happy for the moment).  Is there not a better way to accomplish this?

Thanks!

I have troubles considering such a hack as answering the question.  What is the proper way to achieve this same thing?
