We've been doing tests with the Trial 2019 version of Telerik and we have the following problem:
We have a string type column that can contain both string and decimal values depending on the information that the user needs to display. When the user needs to filter by between (for example, between 2 and 20), the filter works perfectly and the proper values are being displayed.
However, when the NotBetween filter is used, some values are being filtered out while others are being displayed even though they're inside the range, if we use "NotBetween" for values 0 and 10, values like 2,21 and 4,556 are being shown despite clearly being inside the range.
Is there any fix for this problem or is filtering String columns by NotBetween not an acceptable use case? Thank you for your help.
