I get Failed to compare two elements in the array when trying to filter a simple text column.

************** Exception Text **************
System.InvalidOperationException: Failed to compare two elements in the array. ---> System.ArgumentException: Object must be of type String.
   at System.String.CompareTo(Object value)
   at System.Collections.Comparer.Compare(Object a, Object b)
   at System.Array.GetPivotValue(IComparer comparer, Array keys, Int32 left, Int32 right)
   --- End of inner exception stack trace ---

Seems that this column contains not only string/text data.
Please check data on type before comparing to avoid this problem.

FlyGrid.ColumnFilterChanged event - Occurs when Filter of Column in the FlyGrid is changed.
FlyGrid.ColumnFilterValidate event - Occurs before filter list of the Column pop-ups to validate list of predefined filters.

For some reason when i use filter on a column in a grid that was populated like data = New Object() blabla it hangs up for a while for a few seconds and then applies the filter, although the grid.Rows.Items.Count stays the same as it was before the filter.

On grids populated with .DataSource = objDataset all works well, very fast, and grids total items count changes as it should when the filter is applied.
