DataFilter operations

[Pavel]

Hi,
how can i add all types of operations (Less than, Is greater then, etc.) for type of string?

Hello,

Actually those operators are not applicable for type String. They can be used for values that can be compared through the ">", ">=", "<" and "<=" operations.

Ok, but what if i have custom combobox with strings in right part? But type of left part is for ex. integer. 
Selected value of combobox does not saves because of internal error (can't cast string to int)

Hi,

I am not sure how have you done your implementation so that to filter with the combobox, have you used approach similar to the one described in this help article?

Kind regards,

Exactly that aproach. 
Left part is type of int,
but in right part i've got enumeration of strings.
To build expression to compare two proerties of objects.
