Search "contains" doesn't seem to work.

[Georg Thomas]

Hello there, I have a multi-select dropdown and I'm not able to get contains to work. Any idea what I could be doing wrong?

This is my code in Razor page:

 @Html.EJS().MultiSelect("riskTreatment").Placeholder("- Select risk type(s) -").PopupHeight("200px").Width("300px").DataSource(dataManger =>

     dataManger.Url("/Manage/TreatmentControlsDatasource").Adaptor("UrlAdaptor").CrossDomain(true)).FilterType(Syncfusion.EJ2.DropDowns.FilterType.Contains).AllowFiltering(true).Fields(new Syncfusion.EJ2.DropDowns.MultiSelectFieldSettings

        {

            Text = "ControlFullName",

            Value = "Id"

        }).Render()

It just seems to do "Starts with" only.

Thanks in advance.

Hi Georg, 

 

Greetings from Syncfusion support. 

 

Based on your shared information. We suspect that you want to search the data with contains filter type. When you use the local adaptor, we suggest you handle the server-side filtering action with contains key instead of startswith key.  

 

Kindly refer the code example. 

 

[index.cshtml] 

 

@(Html.EJS().MultiSelect("OrganisationStaffId").Placeholder("Select a staff").DataSource(dataManger => 

     dataManger.Url("/Home/UrlDatasource").Adaptor("UrlAdaptor").CrossDomain(true)).FilterType(Syncfusion.EJ2.DropDowns.FilterType.Contains).AllowFiltering(true).Fields(new Syncfusion.EJ2.DropDowns.MultiSelectFieldSettings 

        { 

            Text = "ShipCountry", 

            Value = "OrderID" 

        }).Render()) 

 

[controller.cs] 

 

public ActionResult UrlDatasource(Data dm) 

        { 

            var val = OrdersDetails.GetAllRecords(); 

            var Data = val.ToList(); 

            var count = val.Count(); 

            if (dm.where != null) 

            { 

                Data = (from cust in Data 

                        where cust.ShipCountry.ToLower().Contains(dm.@where[0].value.ToString()) 

                        select cust).ToList(); 

            } 

            if (dm.take != 0) 

                Data = Data.Take(dm.take).ToList(); 

            return Json(Data); 

        }
