将.NET服务器控件插入到具有HTML Agility Pack的DIV中

Question

I selected a DIVlike this:

var divEl = doc.DocumentNode.SelectSingleNode("//div[@id='" + field.Id + "']");

This DIV is empty. Now I need to add a .NET TextBox server control to this DIV and then send the DIV back to the client. How?

Answer 1

First you need to create an element representing the textbox, add the textbox as a child to the div and save the document to whatever stream you have open to the client.

var xpath = String.Format("//div[@id='{0}']", field.Id);
var div = doc.DocumentNode.SelectSingleNode(xpath);
if (div != null)
{
    var textBox = HtmlNode.CreateNode("<asp:TextBox runat='server' />");
    div.AppendChild(textBox);
}

doc.Save(stream);
