I have a RadGrid with google like filtering working on it. I am creating all the columns based on the columns returned in a DataSet.. so no binding in my ASCX. I want to save the value from the filter in a cookie so that the user doesnt have to filter it on the next visit. I have tried to implement the grdsavingsettingsonperuserbasis.html code but the problem is where to save the filter in a cookie? The google like filtering is in a RadGrid class file which extends some RadGrid methods and you cannot set/access cookies from there. I am pasting my code to better understand that.
Thanks in advance,
Saqib
ASCX:
<
radG:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" AllowPaging="True"
AllowSorting="True" AllowFilteringByColumn="True"
OnNeedDataSource="RadGrid1_NeedDataSource" OnColumnCreating="RadGrid1_ColumnCreating" OnItemCommand="RadGrid1_ItemCommand"
OnItemDataBound="RadGrid1_ItemDataBound">
<MasterTableView EditMode="InPlace" DataKeyNames="SubmitId" AllowFilteringByColumn="True" AllowMultiColumnSorting="true" />
<PagerStyle Mode="NextPrevAndNumeric" />
<Columns>
</Columns>
</radG:RadGrid>

MyCustomeFilteringColumnCS.cs is the same as described in the Google Like Filtering example.
GridSettingsPersister.cs is the same as described in grdsavingsettingsonperuserbasis.html example.
Any help would be appreciated.

If you have implemented the GridPersister class as shown in the example cited by you, then you can pass as a parameter to the LoadSettings and SaveSettings methods the HttpRequest object which is completely valid since those methods are called during the HttpRequest handling cycle.
I hope this information helps.
All the best,
