How to handle unauthorized exception when adding a filter to WinForms GridGroupingControl?
Handle unauthorized exception
The “Unauthorized exception” may be occurred due to application being used inside protected folder in WinForms GridGrouping. Because for every loading and saving of compare operator will be referred within the application folder (bin directory).
In order to resolve this we have implemented the API OperatorStoreDirectory for giving CompareOperatorStore.dat file path as we like. This property gets or sets the location of the CompareOperatorStore.dat file location. The following two things should be ensured while using this.
- The path should be assigned before the filter is wired.
- If you want to store the CompareOperatorStore.dat in your needed folder, you have to give the path as <Location>\\<Folder_Name>\\. So that please make use of below code,
filter.OperatorStoreDirectory = "C:\\temppxs\\"; filter.WireGrid(gridGroupingControl1);
VB
filter.OperatorStoreDirectory = "C:\temppxs\" filter.WireGrid(gridGroupingControl1)
