Good morning,
i am using MVC.ASP net in my project and i'm trying to send the DataSourceRequest to a service , via rabbitmq.

the message should contains all the request filters set in the ui in order to create an excel report. i have tried to use the System.Text.Json serialization but it's not working properly. it serializes only the first level props.
i have found a ".ToJson" extension  but it's returning a Dictionary<string, object>, not usefule here.

can you suggest how to serialize the DataSourceRequest in Json format? with all nested and recursive properties?

the filters can be about dates, strings, combobox, and so on

thanks in advance

I am trying to implement a custom tool in the Kendo Editor, following demo/doc implementation and always getting a typeError of some form whenever the custom tool uses a kendo template.  For example:

@(Html.Kendo().Editor()
    .Name("editor")
    .Tools(tools => {
            tools
        .Clear()
        .Bold()
        .Italic()
        .CustomTemplate(temp => temp.Template(
                Html.Kendo().DropDownList()
                    .Name("ddl1")
                    .DataTextField("Text")
                    .DataValueField("Value")
                    .BindTo(new List<object>
                    {
                        new { Text = "text 1", Value = "Value 1" },
                        new { Text = "text 2", Value = "Value 2" },
                        new { Text = "text 3", Value = "Value 3" },
                        new { Text = "text 4", Value = "Value 4" }
                    })
                    .ToClientTemplate()
                    .ToHtmlString()
                ));
    })
)

In this case the error is as follows:

Uncaught TypeError: Cannot read properties of null (reading 'length')

We are using KendoEditor in our MVC application. When assigend HTML to it it is auto formatting it. E.g.
<p style="font-size:13.3333px;"><span style="font-family:Verdana, Geneva, sans-serif;font-size:14pt;">Dear ABC</></></></span></p><p style="font-size:13.3333px;"><span style="font-family:Verdana, Geneva, sans-serif;font-size:14pt;">We have received your details:&nbsp;</span><span style="color:#ffffff;"><span id="spa123"><span> Certificates</span><table class="tbl" border="1" cellpadding="1" cellspacing="0" style="width:100%;font-family:inherit;font-size:inherit;color:inherit;" ><tr style="font-weight:bold;"><td style="text-align: right">Id</td><td style="text-align: left">name</td><td style="text-align: left">Amount</td><td style="text-align: left">Other</td><td style="text-align: left">Comments</td></tr><tr><td style="text-align: right;">1</td><td style="text-align: left;"></td><td style="text-align: left;"></td><td style="text-align: left;"></td><td style="text-align: left;"></td></tr></table></span></span> <span style="background-color:#ffffff;color:#ffffff;"></span></p>

changing to 

<p style="font-size:13.3333px;"><span style="font-family:Verdana, Geneva, sans-serif;font-size:14pt;">Dear ABC</span></p>
<p style="font-size:13.3333px;"><span style="font-family:Verdana, Geneva, sans-serif;font-size:14pt;">We have received your details:&nbsp;</span><span style="color:#ffffff;"><span id="spa123"><span>Certificates</span></span></span></p>
<table class="tbl k-table" border="1" cellpadding="1" cellspacing="0" style="width:100%;font-family:inherit;font-size:inherit;color:inherit;"><tbody><tr style="font-weight:bold;"><td style="text-align:right;">Id</td>
<td style="text-align:left;">name</td>
<td style="text-align:left;">Amount</td>
<td style="text-align:left;">Other</td>
<td style="text-align:left;">Comments</td>
</tr>
<tr><td style="text-align:right;">1</td>
<td style="text-align:left;">&nbsp;</td>
<td style="text-align:left;">&nbsp;</td>
<td style="text-align:left;">&nbsp;</td>
<td style="text-align:left;">&nbsp;</td>
</tr>
</tbody></table>
<span style="background-color:#ffffff;color:#ffffff;"></span><p>&nbsp;</p>

Here <span> and <P> tags automatically getting closed before table. while extected is all should be in span with <span style="color:#ffffff;">.

Not able to trace why it is happning.

 i.Add()
 .Id(Id.ToString())
 .Name(Id.ToString())
 .Title(Name.ToString())
 .Field(Id.ToString())
 .Label(l => l.Text(Lab + ":"))
 .Editor(e =>
 {
     e.NumericTextBox<Decimal>()
         .Format("c")
         .Value(System.Convert.ToDecimal(Answer));
 });

Posted above is an item on a form unfortunately the Value property doesn't display anything nor does hard coding a number into Value property. However, when I place the same variable into the placeholder property, it does seem to display what its supposed to. Is there a reported bug for why this is happening or perhaps a work around to assist this. 

Thank you in advance for your assistance

Above is grid code , the tool bar is not showing at the top of the grid .

It should show like below example.

I have a grid popup edit template that includes a Kendo dropdown.  I need to pass a model property value as the parameter to the Read() method of the dropdown.  But the model is null when the Read() method gets called.   So the value is always 0.  

I've defined the Field in the parent grid.  I even added it as a column too.  Model.ProductId is always 0.

How do I pass a value from the popup editor model to the controller for the dropdown?

                    @(Html.Kendo().DropDownList()
                        .Name("WarehouseId")
                        .OptionLabel("Select a warehouse...")
                        .HtmlAttributes(new { style = "width: 100%" })
                        .DataTextField("Text")
                        .DataValueField("Value")
                        .Value("-1")
                        .DataSource(source =>
                        {
                            source.Read(read =>
                            {
                                read.Action("Inventory_Warehouse_Read", "Purchasing", new { productId = @Model.ProductId});
                            });
                        })
                        .Height(400)
                        )
