Hi all,

I am trying to display an object in a Kendo grid in a MVC Website, however this object contains a dictionary and it seems like the grid is unable serialize it.

This is the error message I am getting:

Type 'System.Collections.Generic.Dictionary`2[[ExactModels.SalesOrderLine, ExactModels, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null],[ExactModels.Item, ExactModels, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' is not supported for serialization/deserialization of a dictionary, keys must be strings or objects.

I am using Kendo.Mvc.dll version 2015.2.902.545.

And this is the object which contains the dictionary that is causing the problem.

Anyone any idea of how to fix this?

Thanks in advance.

Please find the below code as i want to set default value of dropdown instead of optionlable from  JSON data which is returned
from controller .
 
Please find the below code

public ActionResult GetOrders()
       {
           List<usp_IDQ_GetLicenseDistrictsVO> objresult1 = new List<usp_IDQ_GetLicenseDistrictsVO>();
           objresult1 = objConnection.usp_IDQ_GetLicenseDistricts(User.Identity.Name, true).ToList();
           return Json(objresult1, JsonRequestBehavior.AllowGet); ;
       }

@(Html.Kendo().DropDownList()
              .Name("DropDownList1")

                      //.Events(ev => ev.DataBound("SalesPersonID_DataBound"))
                      .OptionLabel("Select ...")
              .HtmlAttributes(new { style = "width:300px" })
              .OptionLabel("Select ...")
              .DataTextField("District_Id")
              .DataValueField("Location_ID")


                      .DataSource(source =>
           {
               source.Read(read =>
                  {
                      read.Action("GetOrders", "IDTDashboard");
                  })
                  .ServerFiltering(true);
           })
           .AutoBind(false)

I would like to setup a validation rule that would conditionally be applied.  For example

I have three fields

Status:  Enum field (​pending, approved, denied)
Denied Code: (price, qty, misc..., ect...)
Comment (Long text)

So if the Status is equal to denied I want the Denied Code and Comment to require an update otherwise ignore them.  Is this possible? and if so how would I go about doing this?  Also the value of the Denied Code must not equal none.

Hello, I just started working with the product.  I created a grid using the MVC control.  Also, the grid is using a custom pop up form when editing/creating a record.

 Inside that custom form, I added a multiselect control. The control should reference values stored in a child table from the record, basically I want to store multiples agencies a person can belong to.  The model have a reference to the child table. 

When submitting the form, the entity object knows that I ​selected X amount of companies, but I cant get to the values. What is the best way of doing this for a child table?

<label for="Agency" class="required col-sm-3 control-label" style="text-align:left;margin-right:-55px">Insurance Companies</label>
            @(Html.Kendo().MultiSelect()
                  .Name("tblAgentInsurers")
                  .DataTextField("InsuranceAgencyName")
                  .DataValueField("InsuranceAgencyID")
                  .Placeholder("Select agencies...")
                  .HtmlAttributes(new { @class = "col-sm-2 form-control", style = "width:70%; height:auto; min-height: 34px;" })
                  .AutoBind(false)
                  .Filter(FilterType.Contains)
                  .DataSource(source =>
                  {
                      source.Read(read =>
                      {
                          read.Action("GetAgencies", "Agents");
                      })
                      .ServerFiltering(true);
                  })

Hi 

I have textbox, a button and a Grid in my screen, i am binding data to it on a button click with the textbox input.

If the user clicks the button again with different inputs, i have to go to DB, get data  and append the new data to the existing Grid data.

I should not lose the existing data and i need to append new data to the same grid I should be able to call the same URL to get data.

Please let me know how I can achieve this.

Sample Code: 

<input type="text" class="k-textbox"/>

<button id="btnAdd">Add</button></td>

<div id="grid"></div>
<script>

 $("#btnAdd").on('click', function () {

$("#grid").kendoGrid({
                dataSource: {
                    type: "json",
                    transport: {
                        read:
                            {
                                url: // my url with textbox inputs,
                                cache: false
                            }
                    },
schema: {
                        model: {
                            fields: {
ID: {type: "string"},
Name: {type: "String"}
   }
                        }
                    },

 columns: [
                //{ hidden: true, field: "AssetID", editable: false },
                { template: "<input type='checkbox' class='checkbox' />" },
                { field: "ID"},
                { field: "Name"}]
 }).data("kendoGrid");
});
});

</script>

I have a Project that uses Entity Framework as it data source, and I have a Kendo grid for that data set. 

The Grid populates find while running from my development box but when I publish it; it just spins and nothing happens no error "nothing".

I have confirmed that the published page is talking to the Database as I can create a normal Model and for loop and return the data into a default div list.  The query generated for the page does take about 3-4 seconds to process which I really can't speed up due to the size of the tables, it only returns though at most 100 records. 

 Below is the Index page 

And here is the Controller:

Here's what I'm doing:

// client side:

//I get a grid datasource filter

var fs = grid.dataSource.Filter()

// I then stringify it and pass it over to the server via an ajax call

// server side, I get the full filter string

// now i do this:

DataSourceRequest dsr = new DataSourceRequest();

Question:  How do I take that filter string and recreate the full datasource Filters ?

p.s. I have to do it this way - I cannot have a DataSourceRequest in the endpoint parameters passed in.

I'm sharing a datasource between a grid and listview. Everything works great - except when the user groups in the grid - the listview is unable to deal with a datasource having groups.  Sorting and filtering works great.

 Would it be possible in the future to consider adding grouping to listviews where the listview code would use the same datasource functionality as found in the grid grouping functionality?

 Thanks,

 Rene.
