Passing values from Javascript to Asp.Net

The trick to passing data from Javascript and Asp.Net is to use hidden inputs in the html. The hidden inputs should have the runat="server" attribute. For example:

<input type="hidden" runat="server" id="hiddenfield" value="" />

Then in the Javascript, whatever value you are trying to pull from Asp.Net,
set the hidden field using:

document.getElementById("hiddenfield").value = "whatever value you want to set"

And in the Asp.net form, you can just access the hiddenfield by using its id.

string x = hiddenfield.value.text

Thats all there is to it. You might need to check the syntax of it first as this is just all from my head.

Parsing XML in .NET

Let's say you have XML as <root>    <item>       <name1>value1</name1>       <name2>value2</name2>       <name3>value3</name3>    </item>    <item>       <name1>value1</name1>       <name2>value2</name2>    </item> </root> To parse it we use the .NET XmlDocument class: // Create the XmlDocument object XmlDocument xmlDoc = new XmlDocument(); // Load the Xml into the object xmlDoc.Load(objResponse.GetResponseStream()); // Get the element like it was a path XmlNode errorNode = xmlDoc.SelectSingleNode("root/item/name1"); if (errorNode != null) { litResult.Text = errorNode.InnerText; return; }
