Hi,
I have a problem with a client installation. All other ultrawingrids display correctly except from this one.It does not display columns or cells.
The first grid is how it looks to the problematic client and the other grid is how it looks on all other clients (correctly). We have more than 30 installation of the specific application and only this customer has this problem. The client has 3 pcs all with different OS (XP, Windows 7) and all have the same problem.
Where is the grid's DataSource coming from?
My first guess would be that this is not a problem with the grid, but rather with the accessing of the data. If your grid data is populating from SQL, for example, the user's machines might not be able to retrieve the data for some reason.
As a test, you might try creating a simple application that gets the same data and binds it to the DataGridView, or a ComboBox, just to see if the client machines can get the data.
Thanks for the reply, but as I said, we have 30 client installations and it works as expected on all of them, and only this particular customer shows this problem. We have been using that particular grid for the past 3 years and this is the first time I see this.

I'm not sure I understand your point here. If you have one client who is getting no data, then clearly something is different at that client location.
Since the problem occurs on 3 different machines at the same client location, the likelihood is that it's something general at the client location like their internet connection or their firewall that is preventing them from accessing the data source. A quick test app that attempt to access the same data source your real application uses would verify that.
Another option is that there is some other software they are running on all three machines which is somehow affecting your application.
Another thing you could check is that your installation program is actually installing the correct dll's (of the correct versions) on the client machines. But there's no version of the grid that was ever released that has a bug in it that was so bad that it shows no data at all. At least not to my recollection.
