Data Mirroring and Transparent Client Redirection

SharePoint 2010 provides a new client object model that enables you to create SharePoint solutions that run remotely from the SharePoint server farm.

This video provides an overview of how to use the client object model from a Windows Presentation Foundation application. (Length: 5:38)

I'm ok (I think) with using a data bound Custom Control on the server to get hold of my data (it will be part of a larger dataset) and to ultimately pass updates to the database.  The bit I'm researching at the moment is passing that data to and from the client. One way to pass the data to the client is to use JSON within the Pageload event to construct a set of Javascript objects (one per row in the data).  Is that the best way, or am I missing something? Then, after the data has been manipulated on the client, I need to pass the rows back again so that the server side code can pick them up and process the updates.  I've seen a suggestion on here that a hidden text field is one way to do that.  Is it the best? Neither of my approaches seem to be at all elegant - and I suspect that I am missing something fundamental in ASP .NET AJAX! Thoughts welcome, Thanks, Nick

Hello!I'm currently working on a project and I want to make as much things as possible performing on client side - with as little loading as possible.The project consist of three "main" pages. On one page I use jQuery DataTable plugin which is working great. One page has tabs (using jQuery). I want to put datacontrol (repeater) on this site and when  user selects one item in dropdown, data in repeater loads on client side, without performing the action on server.I wonder if this is possible and if somebody can give me some case to help with?Thanks!I hope I was clear enough. all the best

    <p>        <%using (Ajax.Form("ExamineTextBox", new AjaxOptions { UpdateTargetId = "result" }))         { %>             <%= Html.TextBox("textBox1")%>             <input type="submit" value="Button"/>              <span id="result"/>      <% } %>     </p>code slice of a sample view page(notice "Ajax.Form"):  <p>       <%using (Ajax.Form("ExamineTextBox", new AjaxOptions { UpdateTargetId = "result" }))        { %>            <%= Html.TextBox("textBox1")%>            <input type="submit" value="Button"/>             <span id="result"/>     <% } %>    </p>But if ajax request functionality is disabled/forbidden on the client side, I still wanna carry on the request , maybe in a normal http request way(mean refresh the whole page instead to at least get the data back). Is it

Hi All, I am working on WCF Data service which imported stored procedure, as below.         [WebGet]        public List<GetMTSearchResultTest_Result> GettMTSearchResultTest()        {            MediaMarketResearch_PRODEntities ent = new MediaMarketResearch_PRODEntities();            return ent.GetMTSearchResultTest().ToList();        } when i consuming this in my client application it says error as "The closed type MMRClient.MMRServiceReference.GetMTSearchResultTest_Result does not have a corresponding element settable property."

Hi, I'm trying to get most of the data I have on my web page, to update a query during an asp 2.0 raisecallback event. I've tried Request.Form with no luck. I've got the html (sent in raisecallback parameter) using 2 div tag's innerhtml. Can someone tell me an efficient method to use to get all this data for updating - Do I have to parse from the callback string (eventArgument) & if so can I use a reader of somekind, or is there a better way? Please provide example & thanks in advance for any help!!

Hi all, This is a saga from a post that was recently answered:http://forums.asp.net/t/1598187.aspxMy main problem is the lack of client side validation when we use a child model class, the server side validation works like a charm whether you use the virtual/override solution or the new attribute on the child class with the getter and setter linking the property to the base class's one.The client side validation does not work with none of the solutions presented below.This is a sample code of the first solution: [Serializable] public class DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] public virtual int? Year { get; set; } ... } [Serializable] public class BirthDateViewModel : DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] [YearRange(ErrorMessageResourceType = typeof(App_GlobalResources.Messages), ErrorMessageResourceName = "Validation_Range")] public override int? Year { get; set; } ... } This is a code sample of the second solution : [Serializable] public class DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] public int? Year { get; set; } ... } [Serializable] public class BirthDateViewModel : DateViewMod

Hello,Is it possible to push server from server to client?  For example (assuming inProc state management), there are three currently active sessions.  An event occurs in the server which causes it to 'push' data updates to all of these active clients?I've been banging my head against this one for a few days now - please help!Thanks,Mark.

hi all, Not sure if there is an easier way to do this but this is my first ever Function I created so far. I am getting the error: "Select statements included within a function cannot return data to a client" All I am trying to do is ...if the date is NOT passed then apply NULL as the default value and run the SELECT statement. If the date IS NOT null then run a different SELECT statement. CREATE FUNCTION [SchemaTest].[fn_Test] ( @instance as uniqueidentifier ,@date as datetime = null ) RETURNS varchar(8000) AS BEGIN If (@date is null) --@date = null ?? Begin Select * From Uds.RealtimeLogging Where instanceID = @instance End Else Begin Select * From Uds.RealtimeLogging Where instanceID = @instance and [timeStamp] > @date End Return @stepIds END Thank you!JCD

Hi I have implemented wcf data service with entity framework with the following steps, i want to know i can we consume this WCF Data service in different format like (SOAP, JSON, XML, PLIST). it will be helpfull if some one help on this. - Created web application with VS2010 and added edmx file and selected tables,views and SPs that i want to use - imported SP with complex type by using function import. - Created WcfDataservice (.svc File). - in SVC File i have added [webget] method as follows.         [WebGet]        public List<GetSearchResultWithComplextype_Result> GetSearchResultComplextype(string email, string Title, string Color)        {            Entities db = new Entities();            var query = db.GetSearchResultWithComplextype(email, Title, Color);            List<GetSearchResultWithComplextype_Result> caseList = query.ToList<GetSearchResultWithComplextype_Result>();            return caseList;        } - created one more client application and added service reference. here i want to cons
