Does anyone know where to find a good example of using XMLHTTP with C#? All the examples I have found are using ASP...

Or maybe someone can think of another helpful solution to my problem. I made an autocomplete script for an asp.net text box which populates a javascript array with a bunch of values from a dataset. There are prolly 5,000 records and the page takes forever to load. I want to use javascript to disable the textbox, load the array into the page using XMLHTTP and then enable the textbox when it is done loading, but make the page usuable while loading the big chuck o'data.

yeah!

Jenni,

From what I gather from you post it shouldn't matter what the example they have is in. There will be two pieces to what you are building. You have to write the javascript that will use the XmlHttp object on the client to retrieve the data and you need to create the ASP.NET page to provide the data. The sample from ASP should be enough to provide the client side stuff as it needn't be much different than it is already because it should be mostly javascript. The server side portion just needs a little convertion to work in C#.

Hi Peter,

I guess you are right, I just assumed that a different methadology would go into implimenting xmlhttp on a aspnet page.

How would you instatiate an xmlhttp object in dotnet, similar to this line of code does in asp:

Server.CreateObject("MSXML2.ServerXMLHTTP")

I couldn't find a namespace that contains any xmlhttp functality in the .net framework.

Because there isn't any. There is the System.Xml namespace in .NET. But you don't need that (well, at least from the end it seems you are worrying about. You need to create the XMLHTTP object on the client side to parse the xml you'll get from the server. You can build the XML at the server any way you wish. You'll want to use the classes in the System.Xml namespace to do that.
