Hello Vittorio,

Currently the context parameter is "null" as the RadListView control has some limitations with the LoadOnDemand functionality. However we are in a process of fixing this issue and the context parameter will properly work for some of the upcoming official release.

W.r.t to Excel like filtering in radgrid. I am trying to call a webservice using - FilterCheckListWebServiceMethod

Requirement : To use Webservice , I have 40 columns so planning to send Column name as a context to WS method and reuse the select query for all..

eg) FilterCheckListWebServiceMethod="LoadDistinctValues"

 

[WebMethod] public RadComboBoxItemData[] LoadDistinctValues(Dictionary<string, object> context)

{     

   IDictionary<string, object> contextDictionary = (IDictionary<string, object>)context;

   ........ The following context is NULL

 

Sample:

  <telerik:RadGrid ID="rd" runat="server" AllowFilteringByColumn="true" FilterType="HeaderContext" EnableHeaderContextMenu="True"
                         EnableHeaderContextFilterMenu="True" AllowPaging="True" PageSize="35"
                         AllowSorting="true" Width="100%" >
                <PagerStyle Mode="Slider" Position="TopAndBottom" PageSizes="100,200,400,500" AlwaysVisible="True" />
                <ClientSettings Scrolling-AllowScroll="true" Scrolling-UseStaticHeaders="true"  EnableRowHoverStyle="true">
                    <DataBinding Location="loadOnDemand.asmx" SortParameterType="Linq" FilterParameterType="Linq">
                    </DataBinding>
                </ClientSettings>
   <MasterTableView CommandItemDisplay="Top" DataKeyNames="ID" HorizontalAlign="NotSet" EditMode="Batch" AutoGenerateColumns="False"
                             AllowAutomaticDeletes="False" Font-Size="9" FilterItemStyle-HorizontalAlign="Center" Width="100%"
                             TableLayout="Fixed" CheckListWebServicePath="loadOnDemand.asmx">

                    <telerik:GridBoundColumn DataField="VERIFIEDBY" HeaderText="Verified By" ColumnEditorID="ceVERIFIEDBY"
                                             SortExpression="VERIFIEDBY" UniqueName="VERIFIEDBY"
                                             AutoPostBackOnFilter="true" CurrentFilterFunction="StartsWith"
                                             FilterControlWidth="80px" HeaderStyle-Width="140px" FilterCheckListWebServiceMethod="LoadDistinctValues"  >
                    </telerik:GridBoundColumn>

Hi Srikrishna,

As this thread is rather old I would suggest you to open a separate thread and provide more detailed explanation for the scenario you are trying to implement and the issue you are facing with it.
