I'm getting an "Ambiguous match found" exception when loading a control with the RadGridView on it. The error is only happening on a few user's PCs and is fine on all the others and there's nothing obviously different about these PCs or the setup.
Are there any known issues that might cause this?
The stack trace is below and you'll see there's none of my code in there - it's purely Windows forms loading and I think formatting rows in the control. The affected PCs are based in Ireland and we are using regional formats on some of the data. There's a DataCellTemplateSelector that determines whether to format a row using one of the following string formats: {}{0:#,#.}, {}{0:C2}, {}{0:C0} or {}{0:#,#.%}
Thanks

I tried to reproduce the behavior but without any success. Would you share a bit more details so that I can give it another try:
1. Do you have a custom style for GridViewRow?
2. What exactly does the template selector do
3. Do you reproduce the exception if GroupRenderMode property of RadGridView is set to "false"?
4. Are you working with XAML or NoXaml binaries?
5. Do you work with the IsExpandable property of GridViewRow?

I have managed to track the issue down to the formatting.
My ItemsSource is a ​DataTable. The first column contains an object with information I use to format the data, so it has properties such as "IsBold".
I'm using a RowStyle with the following setter:
<Setter Property="Background" Value="{Binding Item[0].RowColour, Converter={StaticResource ColourBrushConverter}}" />
This accesses the Item property of the row and the first column in the table (0) to access my format object.
As I mentioned this all works fine everywhere on this planet apart from 3 PCs in Ireland.
After a lot of digging I eventually changed the setter to:
<Setter Property="Background" Value="{Binding ItemArray[0].RowColour, Converter={StaticResource ColourBrushConverter}}" />
By accessing ItemArray​ instead of Item the problem stopped!
I now have a fix and hopefully someone else will benefit from this. There may also be a bug somewhere in the Grid that can be fixed.
Thanks a lot for sharing the solution you have found with the community.
As a side note, just in case you find it appropriate for you scenario, you can also try working with RowStyleSelector.
