Hi,
I have a grid that works fine with HTML.ActionLink ....

    
            <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<BCAnalytics.Models.CompanyVM>>" %> 
        
            <%if (false)  
        
              {%> 
        
              <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> 
        
             <% }%>    
        
               <p><%= Html.ActionLink((String)Resources.BCAResources.stdClose, "Index", "Work", new { workindex = 0 }, null)%></p>   
        
                    <%= Html.Telerik().Grid(Model)  
        
                          .Name("CompanyGrid")  
        
                          .Columns(columns => 
        
                            {  
        
                                // columns.Add(o => o.cMemberNo).Width(30);  
        
                                // columns.Add(o => o.cCompanyNo).Width(30);  
        
                                columns.Add(o => o.cCompanyName).Width(175).Title((string)Resources.BCAResources.coxCompany)  
        
                                   .HtmlAttributes(ID="cname");  
        
                                columns.Add(o => o.cPhone).Title((string)Resources.BCAResources.stdPhone).Width(75);  
        
                                columns.Add(o => o.cGroupCode).Title((string)Resources.BCAResources.coxGroupCode).Width(100);  
        
                                columns.Add(o => o.cEmail).Width(120).Title((string)Resources.BCAResources.stdEmail).Width(150);  
        
                                columns.Add(o => o.cDateUpdated).Format("{0:MM/dd/yyyy}").Width(85).Title((string)Resources.BCAResources.stdUpdated);  
        
                                columns.Add(o => o.cCompanyNo).Format(Html.ActionLink((String)Resources.BCAResources.stdEdit, "Index", "Work", new { workindex = 2, OtherParms = "{0}" }, null).ToString()).Encoded(false).Title("").Width(32);  
        
                                columns.Add(o => o.cCompanyNo).Format(Html.ActionLink((String)Resources.BCAResources.stdDelete, "CompanyDelete", new { Id = "{0}" }, null).ToString()).Encoded(false).Title("").Width(50);  
        
                            })  
        
                           .Ajax(settings => settings.Action("_AjaxBindingCompany", "Company"))  
        
                           .Pageable()  
        
                           .Sortable(sort => sort.SortMode(GridSortMode.MultipleColumn))  
        
                           .Scrollable(scrolling => scrolling.Height(200))  
        
                           .Filterable()  
        
                           %> 
        
             <p><%= Html.ActionLink((String)Resources.BCAResources.coxFormEntry, "Index", "Work", new { workindex = 2, OtherParms = "Create" }, null)%></p>

But when I try to use AJAX.ActionLink, I get the error "

Input string was not in a correct format.
I have tried several variations of this line of code, wont list them all here, but this is the latest one I have tried.

    
            <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<BCAnalytics.Models.CompanyVM>>" %>

I tried to find some examples of this, but the ones I found working with Telerik MVC Grids did not seem to work. I know I am not seeing something ?

thanks for your time.

Hello IQworks,

This is because Ajax.ActionLink outputs "{" and "}" which are then treated as format parameters. To fix this problem try this:
Ajax.ActionLink("Del", "CompanyDelete", new { Id = "{0}" }, new AjaxOptions() { UpdateTargetId = "CompanyGridr" }).ToString().Replace("{", "{{").Replace("}", "}}")

Hi IQworks,

The Format method accepts a string specifying the format of the column. That format is later used internally to format the data. Check the columns help topic for additional info.

If you want to manipulate the actual date you use the Template method.

I tried this way:

columns.Add(o =>

{

<%= DateHelper.ToStringFormat(DateTime.Now) %>

}).Title("Edit");

but I get:

Cannot use templates in Ajax or WebService binding mode

Description: Anunhandled exception occurred during the execution of the current webrequest. Please review the stack trace for more information about theerror and where it originated in the code.

Hello Jose Granja,

Yes, the Template method is introduced with the 2010.1.* release. However I was not talking about it. Please check the help article linked in my previous reply. It explains what the Format method does and how to set the template for server binding.
