I'm using visual studio 2010 and RadControls 2011 q2
Thanks for the help

I am working on xamarin forms and using azure mobile services. When I try to update a record the UpdateAsync does not work and gives me a 404 error.
While debugging I noticed the following line from the debugger:
<b> Requested URL: </b>/tables/Customer/10k<br><br>
10k is the ID.
When I use postman with the link above, it give me back the same 404 error. However, If I used the link /tables/Customer?id=10k it works in postman.
This is the error message from VS.

I found the solution but I ran into another problem .
I had this line on top of customer controller
[Route("tables/Customer")]
I removed it and edited
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
to this
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "tables/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
but now when I update from client it gives me bad request error .
Update
I fixed the bad request error.
in my backend customer class i had datetime? and in my client customer class i have datetime .. i removed the ? .
now i am getting internal server error .
Update 2
In my database the record i was trying to update had some NULL columns , I filled them up and now im getting bad request again .
Update 3
I got it to work . I had two primary keys in the database . When I called the UpdateAsync I only passed one key in the object . when I passed the two keys it worked .
Customer customer = new Customer
{
Id="10k", // first primary key
CustomerId=12, // second primary key
FirstName = FirstNamelbl.Text.ToString(),
LastName = LastNamelbl.Text.ToString(),
DOB = doblbl.Date,
Email = Emaillbl.Text.ToString(),
Sex = GenderGroup.SelectedItem.ToString()
};
// save customer input
await manager.UpdateCustomerRecordAsync(customer);
the manager
public async Task UpdateCustomerRecordAsync(Customer customer)
{
try
{
await customerTable.UpdateAsync(customer);
}
catch (MobileServiceInvalidOperationException msioe)
{
Debug.WriteLine("Invalid sync operation: {0}", new[] { msioe.Message });
}

I am trying to set the SelectedValue of a RadDropDownList in the EditTemplate of my RadGrid. The DataItemBound event appears to be throwing an error on compilation.
ASP.NET
<telerik:GridTemplateColumn DataField="givenAnswer" HeaderText="givenAnswer" UniqueName="givenAnswer">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "givenAnswer") %>
</ItemTemplate>
<EditItemTemplate>
<telerik:RadDropDownList ID="ddlGivenAnswer" runat="server" OnItemDataBound="ddlGivenAnswer_DataBound">
<Items>
<telerik:DropDownListItem Text="Yes" Value="Yes" />
<telerik:DropDownListItem Text="No" Value="No" />
</Items>
</telerik:RadDropDownList>
</EditItemTemplate>
</telerik:GridTemplateColumn>
C#
protected void ddlGivenAnswer_DataBound(object sender, GridItemEventArgs e)
{
if ((e.Item.IsInEditMode))
{
GridEditFormItem item = (GridEditFormItem)e.Item;
RadDropDownList ddl = (RadDropDownList)item.FindControl("ddlgivenAnswer");
ddl.SelectedValue = (string)DataBinder.Eval(e.Item.DataItem, "givenAnswer").ToString();
}
}
Error
CS0123: No overload for 'ddlGivenAnswer_DataBound' matches delegate 'DropDownListItemEventHandler'
This error is being throw on the telerik:RadDropDownList open tag line in ASP.NET. What am I missing here?
Main Edit:
Error CS0123:
First typing CS0123 in Google show me that you were using wrong parameter for your event. Probably a copypast fail. Delete the even in the aspx and ask to intelisense to create a new one. Or copypast this one.
protected void ddlGivenAnswer_ItemDataBound(object sender, Telerik.Web.UI.DropDownListItemEventArgs e)
ItemDataBound:
ItemDataBound occure when a data is bound in a control.
I'am pretty sure that inline declaration are not going to fire this event.
Minor Misconception:
Why would someone change the Value of a selected element dynamically?
It's like changing the value of a vote without changing the vote him self or the name on the vote.
What you want is to check the rigth item.
To check Waldo in the drop down list :
ddlGivenAnswer.FindItemByValue("Waldo").Selected = true;
To check the right Item:
ddlGivenAnswer.FindItemByValue(
DataBinder.Eval(e.Item.DataItem, "givenAnswer").ToString()
).Selected = true;

The error in the Integration Console sugges that your server is not correctly acknowledging the notification:
http://code.google.com/apis/checkout/developer/Google_Checkout_XML_API_Notification_API.html#responding_to_notifications
Some things to try:
Verify that you are correctly parsing the notification and correctly sending back the acknowledgement.
Verify that the XML response is correctly formated. Unlike HTML, XML parsers are picky about whitespaces, lower vs upper-case, proper syntax in general.
I have a Masterpage (site.master) that calls a View using RenderAction. At the moment the View returns "hello world".
site.master:
<%# Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>
<html>
<head id="Head1" runat="server">
<title><asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" /></title>
<asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server" />
</head>
<body>
<% Html.RenderAction("Test", "Charts"); %>
<asp:ContentPlaceHolder ID="ContentPlaceHolder3" runat="server" >
<p>site.master</p>
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="ContentPlaceHolder4" runat="server" />
</body>
</html>
Test.aspx:
<%# Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
hello world!
ChartsController.cs:
public ActionResult Test()
{
return View();
}
If I update the View to pass in the name of the Masterpage explicitly I get an error when I call RenderAction.
ChartsController.cs:
public ActionResult Test()
{
return View(null, "site");
}
Error:
Content controls have to be top-level controls in a content page or a nested master page that references a master page.
Stack Trace:
[HttpException (0x80004005): Content controls have to be top-level controls in a content page or a nested master page that references a master page.]

How do I go about setting the master page that I want the view to use? Ultimately I will be setting the Masterpage dynamically using a custom ViewEngine (by overriding VirtualPathProviderViewEngine.FindView).
if ( String.IsNullOrEmpty(masterName) ){ masterName = "site"; }
When I set the masterName property in my ViewEngine and then call RenderAction from site.master I get the same error as when I set the masterName property in the Action.
I am using:
Visual Studio 2010
MVC 3
IIS Express
edited: added full site.master markup
Subclass ViewPage<T> and override the OnPreInit() event. In your override,
protected override void OnPreInit(EventArgs e)
{
this.MasterLocation = GetMasterLocation();
base.OnPreInit(e);
}
The GetMasterLocation() method should get the filename of the view (beginning with a "~/").
The error comes from the CreateMaster method in MasterPage, the code that throws it is:
if (masterPageFile == null)
{
if ((contentTemplateCollection != null) && (contentTemplateCollection.Count > 0))
{
throw new HttpException(SR.GetString("Content_only_allowed_in_content_page"));
}
return null;
}
So, the MasterPage doesn't exist and content template collection has templates, so the page throws an exception. Following the above instructions will programmatically set the masterpage's location (which gets processed into the virtual path which is the variable masterPageFile)
I have come up with a solution and at least a partial answer/understanding to the cause of my issue.
If I am correct the issue is that I as trying to set the Masterpage on a view that didn't have/need a Masterpage. I think that the result was that I was setting a path to a Masterpage and even though that Masterpage exists the View was not expecting it and through an error.
When I updated the View to use a Masterpage I was able to pass the name of the Masterpage directly to the View without an error.
Test.aspx:
<%# Page Language="C#" MasterPageFile="~/Views/Shared/Charts.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
hello world!
</asp:Content>
The way that I resolved this in my custom ViewEngine was to check if the current View is a ChildAction.
if (String.IsNullOrEmpty(masterName) && !controllerContext.IsChildAction)
{
masterName = "site";
}
