I am using Telerik Radgrid with Excel-like filters for creating my data grids. One issue I face is I cannot filter with symbol '?' or any word starting with '?' like '?check'. It immediately redirects to 500 internal error. If the symbol comes after any other character, the filter works fine, like 'o?c'.
I use RadGrid with DB source and autopopulate columns according to datasource. My filters are Excel-like filters.
I can replicate the same issue in your demo webpage for Excel-like filters too.
Placed screenshots for reference.
Could you let me know what can be done for this? It is absolutely important for me to be able to filter with '?'
Thanks and Regards
