    <p>I am trying to sent a JSON format from Client side JQuery using Ajax to ASP.net (C# code behind) and save the data. however i haven't been able to do so. I dont have much knowledge on how to handle client side request in Server-side. </p> <p>Thanks in advance!</p> <p>my code is as follow:</p> <p>Client Side:</p> <pre><code>$.ajax( { type: "POST", url: "Default.aspx/save", data: "{'data': " + JSON.stringify(prj) + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { if (response.ok) { prof.stop(); if (response.data) { ge.loadProject(response.data); } else { ge.reset(); } } else { var errMsg = "Errors saving project\n\n"; if (response.message) { errMsg = errMsg + response.message + "\n"; } if (response.errorMessages.length) { errMsg += response.errorMessages.join("\n"); } alert(errMsg); } } }); </code></pre> <p>I'm not really familiar with handling JSON in code-behind so i have tried some approaches and I've got errors code behind in C# : </p> <pre><code> [WebMethod] public static string save (object data) { //String s1 = data.ToString(); //Dictionary&lt;string, object&gt; tmp = (Dictionary&lt;string, object&gt;)data; //DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(string)); //MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(data)); //string obj = (string)ser.ReadObject(ms); string s2 = data.ToString(); GC.GClass g = new GC.GClass(); g.Save(s2); return s2; } </code></pre> <p>GC.GClass code to save the data as in a file:</p> <pre><code>namespace GC { public class GClass { string fileLoc = @"c:\Users\Pouria\Desktop\sample1.txt"; public GClass() { } public void Save(string data) { FileStream fs = null; if (!File.Exists(fileLoc)) { using (fs = File.Create(fileLoc)) { } if (File.Exists(fileLoc)) { using (StreamWriter sw = new StreamWriter(fileLoc)) { sw.Write(data); } } } } } } </code></pre> <p>and in my file in my response and my sample1.txt i get this as output:</p> <pre><code> System.Collections.Generic.Dictionary`2[System.String,System.Object] </code></pre> <p>I couldn't upload images of FireBug but these is the response tab message:</p> <pre><code> {"d":"System.Collections.Generic.Dictionary`2[System.String,System.Object]"} </code></pre> <p>and JSON tab:</p> <pre><code> "System.Collections.Generic.Dictionary`2[System.String,System.Object]" </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
