Bug in Datagridview designer? Columns disappears

I'm having a weird problem with a datagrid i'm working on.

Everything was fine, with about 10 columns nicely adjusted, and then i edited one column, and when clicking OK, all columns had disappeared. Then i press ctrl-z and they get back, but not aligned like before, and some columns missing. I can't ctrl-z anymore.

Now when i try to add the missing columns, i can't use the original name, because it claims it's "not a valid identifier". If i edit the name in code it works - but still - if i edit any columns with the designer, all columns will get whiped again.

Does anyone know what may cause this?

I am having this problem as well.

The only workaround I have found is to allow the recreation of the columns. The reason the name is invalid is because there is still a declaration of the columns in the Designer.cs file. If you go all the way to the bottom and delete the references, you can recreate the columns with the original names.

However, I hesitate to go through all the work of recreating columns when I don't know what caused the problem in the first place.

Anyone can help to replay this issues?

The only solution I can find is to manually open the .designer.vb file and delete all references to your missing columns and then recreate the column in the designer. For 1 column I had to delete two lines in seperate sections and a whole section with the properties of the column.

If you have a lot of properties to set I daresay you could cut them out, recreate the column, and paste them back...

Hope this helps someone...

I too have had this problem. I resolved it, but this is a guess as to what the problem was.

My last column had a name in the SQL server that had spaces in itbut was held in [] brackets. I renamed the field in the query definition with no spaces. When I updated the data set and then added the column to the datagrid view, my columns did not disappear.
