I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?
I'm working on some stuff for an in-house CRM. The company's current frontend allows for lots of duplicates. I'm trying to stop end-users from putting in the same person because they searched for 'Bill Johnson' and not 'William Johnson.' So the user will put in some information about their new customer and we'll find the similar names (including fuzzy names) and match them against what is already in our database and ask if they meant those things... Does such a database or technology exist?

View 4 RepliesI am designing an ASP.NET web application (.NET 4.0) which basically has a page that should interact with the code behind every 1-2 seconds (Using Client callbacks or PageMethods via ScriptManager or jQuery.ajax) It'll be hosted on an intranet, so a 1-2 second refresh rate is kind of reasonable.
How can I make the page to access the web service/pagemthod in the code behind in a timeply manner (e.g. every 1 second). Should I use a javascript timer (I'm not familiar with javascrip very much)?
Although the site is hosted on an intranet, but I still need to implement a good approach to reach the desired refresh rate. the amount of data being transfered is about 1KB in each interaction. What are your recommendations on my design regarding this? (using callbacks or ScriptManager or jQuery.ajax,...

View 4 RepliesI ultimately need to show countries in one drop down then states/provinces drop down of the previously selected drop down. I'm sure everyone has seen this many times. My page shows the countries but does not show values in the province/states drop down. It's as if the webservice is never run. I've tried removing and adding the ajaxtoolkit reference. The tableadaters run simple working sql code. I'm really at a lose here.

I've added a class library project to my application.
In one of my classes, I need to use the MembershipUser class, but the project can't find it. I've added references to System.Web, System.Web.Security, and System.Security.Principal.
I'm programatically looking ito a .aspx file and getting the file class name declared in its CodeBehind. For example, when analyzing myFile.aspx I read in its Page Directive and found its CodeBehind equals "myApplicationmyPage.aspx.vb". Then I use the code
below:
[Code]....
Now I want to read the BaseFile (class = myApplication.Forms.BasePage). However, to read in this file, I need I need to get its full path instead of its namespace.class hiearchy. In this case, the BasePage is wrapped in a different namespace declaration thus I cannot just change the '.' to '' in order to get the path.How can I get the path of BasePage so I can read it?
I can't see it nowhere in Visual Studio's Solution Explorer. The tutorial that I am following is using the Northwind database and hence the need to add the code line "using NorthWindTableAdatpter;" statement.So I thought I needed to add "using myDBTableAdapters" statement in my code which I did, but it's giving an error saying:
"The type or namespace name 'myDbTableAdapters' could not be found (are you missing a using directive or an assembly reference?)"
What's wrong? Where is the class for myDB's table adapter? I searched the .xsd file, but there's no mention of "myDBTableAdapters".It's not there in the Solution Explorer.
i am trying to follow this:
http://www.communitymx.com/content/article.cfm?page=2&cid=E8E8CE970C6AB073
but i am having trouble with the first bit. i have built the pages, but i cant work out the whole proxy class bit. I cant find wsdl.exe or operate it... ive downloaded sdk's and still cant find it..
i have xp home, so does this mean no iis?
is there another way to achieve what the tutorial is doing without having to build a proxy class etc?
I have this Control directive in a usercontrol (i've changed the namespace and class name):
<%@ Control Language="C#" AutoEventWireup="true" Inherits="Namespace.Path.To.ClassName" %>
<asp:TextBox runat="server" ID="txtComment" TextMode="MultiLine" ValidationGroup="comment" />
ClassName is a class that lives in a class library and this is the class:
namespace Namespace.Path.To
{
public class ClassName : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.TextBox txtComment;
protected void Page_Load(object sender, EventArgs e)
{
HttpContext.Current.Response.Write(txtComment == null);
HttpContext.Current.Response.End();
}
I have build a UserControl with separate code behind file.In that code behind file i have defined some public properties in the Partial class of user control that was automatically generated.Those properties will initialize some properties of controls that are used in the control.Now, in .aspx page i used this User Control and initialized the public properties through code behind of aspx page for dynamic contents.
