I'm enhancing our ticket tracking system to allow users to organize the priority of their tickets similar to a Netflix queue.  I'm using the RadGrid to display all the tickets with an "Precedent Number" column that is a HtmlHelper.TextBox inside of an ItemTemplate column.

The view code looks like this:
<% using (Html.BeginForm()) {%> 
    <div style="width: 100%;"
        <div style="float: left;"
            <input type="submit" value="Save Queue Changes" /></div
        <div style="float: right; text-align: right;"
            <%= String.Format("{0} Tickets in Queue", Model.Rows.Count) %></div
    </div> 
     
    <telerik:RadGrid ID="rgTickets" runat="server" AutoGenerateColumns="false" Style="clear: both;"
        <MasterTableView DataKeyNames="CallId" EditMode="InPlace"
            <Columns> 
                <telerik:GridTemplateColumn> 
                    <HeaderStyle Width="50px" /> 
                    <ItemStyle Width="50px" /> 
                    <ItemTemplate> 
                        <%# Html.TextBox("Precedence", Eval("Precedence"), new { width = "25px" })%> 
                        <%# Html.ActionLink("Move To Top", "MoveToTop", new { ticketId = ((System.Data.DataRowView)Container.DataItem)["CallId"], queueId = ((QueueDefEntity)ViewData["QueueDef"]).QueueId })%> 
                        <br /> 
                        <%# Eval("InsertDate").ToString().Length > 0 ? string.Format("Prioritized by {0} <br />{1}",Eval("InsertUser"),Eval("InsertDate")) : "" %> 
                    </ItemTemplate> 
                </telerik:GridTemplateColumn> 
                <telerik:GridBoundColumn DataField="CallId" UniqueName="CallId" HeaderText="Ticket Number" /> 
                <telerik:GridBoundColumn DataField="CallDesc" UniqueName="CallDesc" HeaderText="Problem Description" /> 
                <telerik:GridBoundColumn DataField="ReceivedTimestamp" UniqueName="ReceivedTimestamp" 
                    HeaderText="Received" DataFormatString="{0:dd MMM yyyy h:mm tt}" /> 
            </Columns> 
        </MasterTableView> 
    </telerik:RadGrid> 
    <% } %> 

When the user clicks the "Save Queue Changes" submit button, how do I get at the values inside of each text box?  My view is typed as such:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Data.DataTable>" %> 

...what should I be expecting in my controller action method as a return value to enumerate through all the rows in the grid?

Hello Nick,

You may retrieve the values from the posted fields inside the Controller using a Request's Form object.
Please refer to this blog post for an example of how to update data using RadGrid control in a MVC environment.
