RadGrid CheckList Filtering not working when more than one option checked

[ck]

using 2014.3.1024.45. I am using a RadGrid with checklist filtering, nothing special. Wen two options from the listbox are checked, the radgrid doesn't filter properly, also when two or more columns are filtered at the same time. here's my markup

<telerik:RadGrid ID="grdProjects" runat="server" AllowFilteringByColumn="True" AllowSorting="True" AutoGenerateColumns="False" OnItemCreated="grdProjects_ItemCreated" FilterType="CheckList"
        GroupPanelPosition="Top" ShowGroupPanel="True" OnNeedDataSource="grdProjects_NeedDataSource" AllowPaging="True" ShowFooter="True" CellSpacing="-1" GridLines="None" OnFilterCheckListItemsRequested="grdProjects_FilterCheckListItemsRequested">
        <ClientSettings AllowDragToGroup="True" ClientEvents-OnRowClick="openProject">
            <Selecting AllowRowSelect="True" />
        </ClientSettings>
        <ItemStyle CssClass="popup-trigger" />
        <AlternatingItemStyle CssClass="popup-trigger" />
        <MasterTableView DataKeyNames="ProjectID,IsLead" ClientDataKeyNames="ProjectID,IsLead">
            <Columns>
                <telerik:GridBoundColumn Visible="false" DataField="ProjectID">
                    <ColumnValidationSettings>
                        <ModelErrorMessage Text=""></ModelErrorMessage>
                    </ColumnValidationSettings>
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Title"  AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" FilterControlWidth="250" HeaderText="Title" UniqueName="Title" DataType="System.String" Aggregate="Count" FooterText="Total Projects:">

                    <ItemStyle Width="45%" />
                </telerik:GridBoundColumn>
                <telerik:GridTemplateColumn FilterControlAltText="Filter ResponsibleOfficerID column"  FilterCheckListEnableLoadOnDemand ="true"  HeaderText="Responsible Officer" UniqueName="ResponsibleOfficerID" DataField="NAME" SortExpression="Name">

                                <td nowrap="nowrap"><%# Eval("NAME") %></td>
                            </tr>
                        </table>

            </Columns>
        </MasterTableView>

    </telerik:RadGrid>

and my code behind

protected void grdProjects_FilterCheckListItemsRequested(object sender, GridFilterCheckListItemsRequestedEventArgs e)
       {
           string DataField = (e.Column as IGridDataColumn).GetActiveDataField();
           var ds = ProjectModel.GetAllProjects();
           switch (DataField)
           {
               case "ProjectID":
                   e.ListBox.DataSource = ds.Select(p => p.ITCProjectID).OrderBy(p => p).Distinct().ToList();
                   break;
               case "Title":
                   e.ListBox.DataSource = ds.Select(p => p.Title).OrderBy(p => p).Distinct().ToList();
                   break;
               case "NAME":
                   e.ListBox.DataSource = ds.Select(p => p.NAME).OrderBy(p => p).Distinct().ToList();
                   break;
               case "TemplateName":
                   var list = ds.Select(p => p.TemplateName).Distinct().ToList();
                   list.Add("Project Lead");
                   list = list.OrderBy(l => { return l; }).ToList();
                   e.ListBox.DataSource = list;
                   break;
           }

Hello,

I tried to replicate the behavior you describe, however I was unable to. I am attaching a sample project I used for testing. It is working as expected on my end. Give it a try and let me know if I am missing something.

I am having the same problem as the post opener.

Whenever I checked 2 options in the filterchecklist, the filtering doesn't work properly.

Hi Calvin,

I tested the behavior and it is working as expected on my end. I made a short video as reference. It is available here.

Take a look at the video and let me know if I am missing something. I would also appreciate it if you can describe what should be modified in the sample from my previous post in order to replicate the behavior that you are seeing.

Hi,

For my case is resolved by one of your colleague yesterday.

It is due to a bug in the control where it doesn't support when I set EnableLinqExpressions="false" 

After I changed it to true then it works like charm.

But hope you can look into the issue on this attributes and resolve in the next release.

Thanks.

Hi Calvin,

I am glad that you have found a workaround for the issue.

The developers are currently working on the bug you are referring to. The fix should be included in the next official release. Please download the next release and see how it works for you.
