Request causes exception before reaching controller: "Expected token" exception on filter attempt

[iCognition]

Here is the post data:

sort=&page=1&pageSize=30&group=&filter=Fields%5B3%5D.Value~contains~'hello'~or~Fields%5B3%5D.Value~contains~'statement'&Query=test

The columns are dynamic so removing the iterator on the Fields collection is not an option

Please provide support for iterable column filters

Never mind fixed it myself.

For kendo developers: FilterLexer.cs

private static bool IsIdentifierPart(char character)
{
     return char.IsLetter(character) || char.IsDigit(character) || character == '_' || character == '$' || character == '[' || character == ']';
}

That function needs to be redone completely IMO I'm sure that there is a better way to figure out what constitutes a valid identifier

Hi,

I'm really struggling with this. 

Can you provide more details on how you fixed it ?

Thanks,

Marco

Hi MARCO,

I have investigated the information that you have provided so far and I can say that we introduce a custom binder that understands the query parameters and parse them correctly into FilterDescriptors. In general, all of the options should be parsed into a DataSourceRequest object. 

Can you share the relevant snippets for the Telerik UI Grid along with the server implementation so that I can replicate the issue locally and look for a solution?

Looking forward to your reply.

 

Kind regards,
