Inside a Datagrid search field there is drop down where I do not want to sort the drop down values and I want to display the values in the same order how in the enumeration it is defined. So in the sort option i left it as default sorting . But in the UI it is getting sorted with ascending order. Strange part is this behavior is not consistent in the other drop down the values are not getting sorted but here in one particular dropdown it is getting sorted without defining any sort.
