We are using a TelerikGrid which allows to filter various properties.
One of our properties is a name of Id, which is of Guid type.
Of course when we give a full Guid Id into the filter, the filter works, but as soon as we put a partial Guid value the filter breaks, because as expected, it cannot parse the given value.
Error: System.FormatException: Unrecognized Guid format.
at System.Guid.GuidResult.SetFailure(ParseFailure failureKind)
at System.Guid.TryParseGuid(ReadOnlySpan`1 guidString, GuidResult& result)
at System.Guid..ctor(String g)
We have tried to convert guid value into string and then pass it into the filter, but it expects a Guid data type.
Is there a way to internally let the guid filter know, that he should expect a string value instead of Guid? Filtering after Guid doesn't really make sense, since user will most of the time just type a part of the full guid Id value.
Thank you for assistence!

Hello Tadas,
The only data type, which supports a "contains" filtering is the string. So, you have two options:
- Change the type of the Id property to string and call ToString() when creating new Guid values.
- Bind the Grid with an OnRead event handler and implement custom filtering on your own without using ToDataSourceResult(). I don't think this option makes sense, because it's a lot more work than the previous one.
