DataSource is not reaching JSONRequest

[axwack]

I have a very peculiar problem. One of my client requests goes to the HomeController and successfully gets the data. The second never gets reached

$("#ResidualRec") 

What could be wrong? 

$("#Accounts").kendoComboBox({

               dataTextField: "AcctName",

               dataValueField: "AcctCd",

               dataSource: {

                   transport: {

                       read: "/Home/GetAccounts"

                   }

               },

               template: $("#scriptTemplate").html(),

               filter: "startswith"

           });

 

           var combobox = $("#Accounts").data("kendoComboBox");

           // set width of the drop-down list

           combobox.list.width(400);

 

           var sharableDataSource = new kendo.data.DataSource({

               transport: {

                   read: {

                       url: "@Url.Action("GetSecurities","Home")",

                       dataType: "json"   

                   },

                   type:"POST"

               }

           });

 

           $("#ResidualRec").kendoComboBox({

               datasource:sharableDataSource,

               filter: "startswith"

           });

This is the webpage value.

<select id="ResidualSec"  data-value-field="Cusip" data-text-field="SecName" data-role="combobox" placeholder="Enter Residual" data-bind="value: Residual"></select>                   

            <select id="UnderlyingSec" data-role="combobox" data-value-field="SecName" data-text-field="Cusip" placeholder="Enter Underlying" data-bind="value: Underlying"></select>

            <select id="FloaterSec" data-role="combobox" data-text-field="SecName" data-value-field="CUSIP" placeholder="Enter Floater" data-bind="value: Floater"></select>

The one that works is as follows: 

<div id="allocation">

    <div class="selector">         

   <select id="Accounts" style="width: 225px" data-role="combobox" data-value-field="AcctCd" data-text-field="AcctName"

                data-bind="value: AcctCd" placeholder="Select Funds..."></select>

Hello Vincent,

The code snippets look OK, but I am afraid they are not enough to detect where the reason for the problem is. Could you please provide a sample project that I can test locally? Thus way I would be able to investigate your case in details and do my best to provide you with an accurate solution. Thank you in advance.

I think the reason is that I am bringing back 55,9k objects as I've tried to use this with a lesser return set.

However, there is no way to know what Telerik complains about. How can you debug something like this?

Hello Vincent,

The most likely reason for the issue is the huge number of objects that are returned. I would suggest to try to enable serverPaging in order to reduce the number of returned rows. Also, you could try to use an AJAX request and observe the behavior in this case.

I hope this helps.
