I have a dropdownlist in a grid. When I put a row in edit mode and change the selected value of the ddl, the data sent to my update procedure is the value field (i.e. 1, 5, 7). What I want to send is the text field (i.e. Apples, Oranages, Bananas).
How can I ensure the text value of the dropdownlist is being sent to my update method?
If I don't change the selection it works like I want (meaning the text value is sent to my update procedure). Only when I change the selected value the parameter value sent is the value field.
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="grid"> </div> <script type="text/javascript"> $(document).ready(function () { $("#grid").kendoGrid({ //height: 260, toolbar: ["create"], columns: [ "DepartmentID", { field: "FRSAccountNumber", title: "FRS Account No", sortable: true, filterable: true }, { field: "DepartmentName", title: "Dept Name", sortable: true, filterable: true }, { field: "CollegeName", width: "150px", editor: categoryDropDownEditor }, { field: "SubjectArea", title: "Subj Area", sortable: true, filterable: true }, { command: ["edit", "destroy"], title: " ", width: "210px", filterable: false } ], editable: "inline", dataSource: { //batch: true, pageSize: 10, schema: { data: function (data) { return data.d || []; }, type: "json", total: "d.length", model: { id: "DepartmentID", fields: { DepartmentID: { type: "number" }, FRSAccountNumber: { type: "string" }, DepartmentName: { type: "string" }, CollegeName: "CollegeName", SubjectArea: { type: "string" } }//fields }//model }, //schema transport: { read: { url: "Web/KendoDS.asmx/ReadDepartments", contentType: "application/json; charset=utf-8", type: "POST" }, //read update: { url: "Web/KendoDS.asmx/Update", contentType: "application/json; charset=utf-8", // tells the web service to serialize JSON type: "POST" //use HTTP POST request as the default GET is not allowed for ASMX }, parameterMap: function (data, operation) { if (operation != "read") { return JSON.stringify({ dept: data }); } } }//transport }, //dataSource pageable: true }); var categoryDataSource = new kendo.data.DataSource({ transport: { read: { url: "Web/KendoDS.asmx/GetColleges", contentType: "application/json; charset=utf-8", type: "POST" } }, schema: { data: "d" } }); function categoryDropDownEditor(container, options) { $('<input data-text-field="CollegeName" data-value-field="Ranking" data-bind="value:' + options.field + '"/>') .appendTo(container) .kendoDropDownList({ autoBind: false, dataSource: categoryDataSource }); } }); </script></asp:Content>2 Answers, 1 is accepted

I did. Below is a mod of what I posted above.
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="grid"> </div> <script type="text/javascript"> $(document).ready(function () { $("#grid").kendoGrid({ toolbar: ["create"], columns: [ { field: "FRSAccountNumber", title: "FRS Account No", sortable: true, filterable: true }, { field: "DepartmentName", title: "Dept Name", sortable: true, filterable: true }, { field: "CollegeName", width: "150px", editor: categoryDropDownEditor }, { field: "SubjectArea", title: "Subj Area", sortable: true, filterable: true }, { command: ["edit", "destroy"], title: " ", width: "210px", filterable: false } ], editable: "inline", dataSource: { pageSize: 10, schema: { data: function (data) { return data.d || []; }, type: "json", total: "d.length", model: { id: "DepartmentID", fields: { DepartmentID: { type: "number" }, FRSAccountNumber: { type: "string" }, DepartmentName: { type: "string" }, CollegeName: "CollegeName", SubjectArea: { type: "string" } }//fields }//model }, //schema transport: { read: { url: "Web/KendoDS.asmx/ReadDepartments", contentType: "application/json; charset=utf-8", type: "POST" }, //read update: { url: "Web/KendoDS.asmx/Update", contentType: "application/json; charset=utf-8", // tells the web service to serialize JSON type: "POST" //use HTTP POST request as the default GET is not allowed for ASMX }, parameterMap: function (data, operation) { if (operation != "read") { return JSON.stringify({ dept: data }); } } }//transport }, //dataSource pageable: true }); var categoryDataSource = new kendo.data.DataSource({ transport: { read: { url: "Web/KendoDS.asmx/GetColleges", contentType: "application/json; charset=utf-8", type: "POST" } }, schema: { data: "d" } }); function categoryDropDownEditor(container, options) { $('<input data-text-field="CollegeName" data-value-field="Ranking" data-bind="value:' + options.field + '"/>') .appendTo(container) .kendoDropDownList({ autoBind: false, dataSource: categoryDataSource }); } }); </script></asp:Content>
