View 4 RepliesI am using the code below (simplified for this example) to post data to a SharePoint list
StringBuilder customerDoc = new StringBuilder();
customerDoc.Append("<Method ID='1' Cmd='New'>");
customerDoc.Append("<Field Name='Name'>" + Name + "</Field>");
customerDoc.Append("<Field Name='Age'>" + age + "</Field>");

xBatch.SetAttribute("OnError", "Continue");
xBatch.InnerXml = sb_method.ToString();
XmlNode xn_return = sharePoint.listsObj.UpdateListItems(ConfigurationManager.AppSettings["SaveCustomer"].ToString(), xBatch);
As you can see I am using a stringbuilder which isn't ideal so I wonder what I should use instead to create an XML string?

WHAT EXACTLY I WANT IS TO RETRIEVE DATA(may be from separate table) AND THEN DISPLAY THEM PUTTING SOME STYLE(font,color etc). Is retrieving from multiple table is possible in gridview ? I could use the DataReader, but how to display them in style(font,color etc)?
In my javascript code I am getting json string from cs file
var tmpString="<%=resultset2%>";
In cs I am concatenating strings to build json string. Here is an issue the json string is returned as a string and it has " with it.
"[{id:'1',name:'Aik'},{id:'2',name:'Aik or Aik'}]"
Because of " in beginning and end javascript code treat it as a string.
I have written such a code to loop through the records and build a string.
Is this s good idea or should I use repeater or something?
