    This example shows how to enable filtering in the grid embedded in RadFileExplorer.

    This feature is offered out of the box since Q1 2011. You can see it in action in this online demo.

    Thanks! Another question, using the code mentioned, how you set filtering to disregard case-sensitivity? I tried adding the line:

    RadFileExplorer1.Grid.GroupingSettings.CaseSensitive = false;

    on page load but it doesn't work.

    Hi Philip,

    The actual filtering is performed manually in the ExplorerPopulated event and you need to implement case insensitive comparison manually. An example implementation is to pass a second parameter StringComparison.InvariantCultureIgnoreCase to the comparison methods. The required changes are highlighted in the code snipped bellow:
    switch (gridKnownFunction)
        case GridKnownFunction.StartsWith:
                e.List = e.List.FindAll(fi => fi.Name.StartsWith(filterText, StringComparison.InvariantCultureIgnoreCase)).ToList();
            }; break;
        case GridKnownFunction.EndsWith:
                e.List = e.List.FindAll(fi => fi.Name.EndsWith(filterText, StringComparison.InvariantCultureIgnoreCase)).ToList();
            }; break;
        case GridKnownFunction.Contains:
                e.List = e.List.FindAll(fi => fi.Name.ToLower().Contains(filterText.ToLower())).ToList();
            }; break;

    Kind regards,
    the Telerik team
