We have used RadGridView in our Windows Application and initially we use 2012 year versions of respective telerik dll's.
With those dll's on our specific form where we have used RadGridView, if user enter a filter value to filter desired type of rows from all bunch of rows and close the and reopen the form user can see his last entered filter value has been retained so the rows user can see are also filtered on the basis of filter value.
But when tried to Upgrade to 2020 version of respective telerik dll's we observed above mentioned functionality does not work.
Attached is the respective image of grid. Kindly assist on this.
