Hi, hows it going?

I have a RadGrid control (2014.3.1024.45) that has paging, filtering, sorting and editing by template enabled. If I enter a filter value, the filter row in the grid disappears after the post back. The user is then unable to remove/change the filtering. Here my code:

<telerik:RadGrid runat="server" ID="rgdAddresses" AutoGenerateColumns="false" ShowStatusBar="true" AllowSorting="True" AllowFilteringByColumn="true"

OnItemCommand="rgdAddresses_ItemCommand"

OnNeedDataSource="rgdAddresses_NeedDataSource"

OnInit="rgdAddresses_Init"

OnItemDataBound="rgdAddresses_ItemDataBound"

OnSortCommand="rgdAddresses_SortCommand">

<MasterTableView DataKeyNames="Id, STACode" CommandItemDisplay="Top">

<CommandItemSettings ShowExportToWordButton="true" ShowExportToExcelButton="true"

ShowExportToCsvButton="true" ShowExportToPdfButton="false"

ShowRefreshButton="false" ShowAddNewRecordButton="true" AddNewRecordText="New STA Address" />

Hi Matt,

This issue is very strange, indeed. Can you check whether you are not hiding the filter item on the code-behind using the Visible or IsFilterItemExpanded properties?

I've created a sample RadGrid web site using the provided mark-up to test the described behavior. On my side the filtering works as expected. Please run the attached application and let me know about the result from your end.
