Hi Team,

We are using cascaded multiselects with serverfiltering set to true.

But when we are typing some characters in the second multiselect, the suggestions are not showing up.

However it is working fine with serverfiltering set to false but in this case the second multiselect is not filtering on selection from first multiselect.

First Multiselect:

@(Html.Kendo().MultiSelect()
                                .Name("drp_Sector")
                                .DataTextField("SectorName")
                                .DataValueField("SectorId")
                                .Placeholder("Select").HtmlAttributes(new { @class = "drpWidth fontforcontrol" })
                                .Events(e =>
                                { e.Change("onChange_SectorPreDefinedComps").DataBound("onDataBound_SectorPreDefinedComps").Filtering("OnFilter_SectorPreDefinedComps");
                                })
                                .DataSource(source =>
                                {
                                    source.Read(read =>
                                    {
                                        read.Action("GetSectors", "ManageComps");
                                    }).ServerFiltering(true);
                                }).AutoBind(false)
                                )

Second Multiselect:

@(Html.Kendo().MultiSelect()
                                .Name("MulSel_SubSector")
                                .DataTextField("SubSectorName")
                                .DataValueField("SubSectorId")
                                .Placeholder("Select")
                                .AutoBind(false)
                                .HtmlAttributes(new { @class = "fontforcontrol" })
                                .Enable(false)
                                .Events(e =>
                                {
                                    e.Change("onChange_SubSectorPreDefinedComps").DataBound("onDataBound_SubSectorPreDefinedComps");

                                })

                                .DataSource(source =>
                                {
                                    source.Read(read =>
                                    {
                                        read.Action("GetSubSectors", "TickComp")
                                        .Data("PostSectorIdPreDefined");
                                    }).ServerFiltering(true);
                                }))

 

Please help asap.

Thanks in advance,

Abhinav

Hello Abhinav,

Could you also demonstrate the implementation for the events that you use for your multiselect The reason for the requested implementation is because I assume that the cascading functionality is implemented in the Change event of the drp_Sector  as demonstrated in our documentation article:

http://docs.telerik.com/kendo-ui/controls/editors/multiselect/how-to/cascade/cascading-multiselects
