Read all data at client side from the RadGrid - batch edit mode

[George]

How can I get all data from the RadGrid at client side to build a json string with the new data?

using the following code I Tried 

01.<telerik:GridTemplateColumn UniqueName="ColDepartment" DataField="DepartmentId" HeaderStyle-HorizontalAlign="Left">
02.<ItemTemplate>
03.      <asp:Label ID="DepartmentNameLbl" runat="server" Text='<%#Bind("Department.Name") %>'></asp:Label>
04.</ItemTemplate>
05.
06.<EditItemTemplate>
07.      <telerik:RadDropDownList runat="server" ID="DepartmentsDdl" DataValueField="Id" DataTextField="Name" OnPreRender="DepartmentsDdl_PreRender"></telerik:RadDropDownList>
08.        </EditItemTemplate>
09.
</telerik:GridTemplateColumn>

1.batchManagerObject.getCellValue(cellObject);

but it gives me the displayed value [DepartmentName] What I need is the [DepartmentId]

Hello,

Is the department id used for another column or set as a ClientDataKeyName? If not the only way to obtain it is to use the DepartmentName to find the respective RadDropDownList  item and obtain the id. An exemplary implementation of this approach is available below.

JavaScript:

var departmentName = batchManagerObject.getCellValue(cellObject);
var item = $telerik.findControl(document,"DepartmentsDdl").findItemByText(departmentName);
var id = item.get_value();
