Hi Andrew,

Sorry for late reply. Both the assemblies with specified version are included in our project, still we are getting issue.

Same XamTileManager component has been working fine with our existing Silverlight application, this issue is coming while migrating it to WPF. log was provided in previous mail.

Hello Hitesh,

Thank you for your update on this matter and verifying that the specified assemblies are included in your project in this case.

It is interesting that you are still receiving this exception. As an additional recommendation in this case, I would recommend cleaning and rebuilding your XamTileManager application, or deletion of the bin and debug folders of your application after exiting and restarting the project, as this issue does seem to have something to do with the assemblies that you are using, specifically.

Would it also be possible for you to please verify the exact version of Infragistics for WPF 2014.2 that you are using? This number would look like 14.2.20142.XXXX.

Is there also any "inner exception" detail on this error that you are receiving? I imagine this issue is happening on startup, and it would be helpful if you could provide any additional information about it.

Another thing that would be very helpful in this case is the XAML code that you using to set up your XamTileManager, or an isolated sample project that reproduces the issue. Would it be possible for you to please provide these?

Please let me know if you have any other questions or concerns on this matter.

Hi Andrew,

I tried with cleaning and deleting bin folder of the project, but it didn't work for us.

Infragistics control exact version is 14.2.20142.2178 and WPF Version is 3.0.6920.5011

Below is the code snippet and exception details.

<igXamTile:XamTileManager Grid.Row="1" Grid.ColumnSpan="2" TileRetentionMode="Retain" >

<igXamTile:NormalModeSettings TileLayoutOrder="Horizontal"/>

<igXamTile:XamTileManager.ItemTemplate>

<DataTemplate>

<igXamTile:XamTile>

<!--<d2DataReview:ReconDatasetView></d2DataReview:ReconDatasetView>-->

</igXamTile:XamTile>

</DataTemplate>

</igXamTile:XamTileManager.ItemTemplate>

</igXamTile:XamTileManager>

Please find below stack trace from exception details, inner exception is null, attaching the screenshot of error.

Hello Hitesh,

Thank you for verifying the specific version of Infragistics WPF 2014.2 that you are using in this case. The XAML code that you have provided looks fine in this case. I have a couple of additional recommendations for you on this matter, though.

1. Check the licenses.licx file of your project, if any exists. Are there references to a different specific version of Infragistics assemblies than 14.2.20142.2178? If so, remove these references from the .licx file. Normally this would be caught at compile-time.

2. If there are any compiled dependencies containing user controls or code libraries with Infragistics references - if these were compiled against a different Infragistics version, this may cause issues.

3. When you do a clean and rebuild of your application, what are the contents of the Bin => Debug folder? If the assemblies that get copied there are not 14.2.20142.2178, this could be the issue that you are seeing, as it points to your application using a different version somewhere. If there are no assemblies there at all, you may need to set the "Copy Local" property to true on your references in your application.

4. Unload your problematic .csproj file and try editing it. Are there any references to Infragistics assemblies inside that are not version 14.2.20142.2178? If so, you may need to change this so that it points at the correct version.

Please let me know if you have any other questions or concerns on this matter.
