I have a dynamic table that creates a div (new panel) for every TD and i want to give this div a class...
Can i add with Attributes.Add or with cssClass a class to the panel?
I am asking becouse i tried with both and got the same resault.... browser crash!!!
Every other attribute works great, and i just don't understand why....
Panel div = new Panel();
div.ID = "div" + "_" + i.ToString() + "_" + j.ToString();
div.Height = _CellHeight;
div.Width = _CellWidth;

Following is the code to insert userName from session and PageName into table to keep record that how many times a user does hit a particular page.
To avoid repitition of code I want to put the code in one class and want to inherit same code in each page.
How to get this task? Please do share with me? Here is the OK code:

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 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.

What is the best way to do so?
Currently how i do this is, i create html table with id & runat="server" tag and then from code behind i add rows and columns to this table, is there some better way to do this job?
I have this control

I want to remove the required class from code behind, how can I do that?
I want have a web application that I am putting together - but I have started to see that some of the things I am writing are repeated over and over, example -
GetDepartments() in the code behind has all the database connections and is linked to a stored procedure.All it does is return Department Names' and Ids', ie then bind them to a dropdownlist.My question is this I have seen Class files - I want to know if I can put this type of information in there and just call it whereever I need it in the site and then bind to whichever dropdownlist I need to?I have had a look around the net and even saw some examples by scott mitchell - but it used datasets (.xsd) files etc and dont want to be using them, plus it was a little over my head. Does anyone know of some good simple examples out there that I can follow, or maybe some examples on here?
i create a class library and i want my code behind the page be there. in my page like login.aspx is a login control and i want to write some code for that but i got some error i don't know what i'm doing rong. the code behind in class library is:

View 2 RepliesI have some code in a button_click event in my webform that performs some actions
(writing some xml files).But i wish to place all my XML code in 1 class within my webproject.But how do i exactly acces controls from my webform on this class?nd how do i link those 2 with each other?Ive tried inherit from System.Web.UI.Page in my class but seems thats not quite it.
I was wondering which of these two is better from the aspect of performance.
I was thinking that possibly Class files stored in App_Code works faster because they are sort of pre-compiled but i am not 100% sure.
Specifically i am overriding onInit event on each page using some functions that i am not certain where to place.
Not that i complaint on the speed but i want to be sure that i am doing the right thing.
I have following two classes:
public class A : System.Web.UI.WebControls.Button
{
public virtual string X[code]....
As you must be seeing the class A and B have exactly the same code , my question is how can I make a common class for it and use these two classes.
I have a function in a code behind file that's used to respond to a gridview event:
protected void GridviewEval(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
foreach (TableCell cell in e.Row.Cells)
{
if (cell.Text == "0") { cell.Text = "-"; }
}
}
}
It's currently in the code behind of a page and I'll be using it in other other pages.I would like to use the same code in other pages.When I cut and paste the function into a class,it's not working.
I am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?
View 1 RepliesI'm just starting out learning ASP.NET. From what I understand, ASP.NET differs from old school ASP in that the logic code for a page exists in as separate file rather then being embedded in the ASP page. So when a user requests a page like ShoppingCart.aspx the server reads the directive at the top ...
<%@ Page Title="" Language="C#" MasterPageFile="~/Styles/Site.Master" AutoEventWireup="true"
CodeBehind="MyShoppingCart.aspx.cs" Inherits="TailspinSpyWorks.MyShoppingCart" %>
This tells the server what file and what class in the file is associated with the page. The code behind class also has member variables that correspond to each control on the page, and provide a way for code in the code behind file to manipulate the controls.
First, do I understand this correctly?
Second, could a site be setup with two separate ASPX pages with identically named controls, which both had a directive pointing to the same file and class? Would you even want to do this? Both pages could have the same functionality but a different layout. I was thinking this could be a way to create separate "desktop" and "mobile" versions of a page with out duplicating content in the code behind files.
I guess ultimately what I'm wondering, is if there a way to define an abstract page? Say create an abstract page definition that says a page must have controls "cart_list", "total_lbl", but then be able to have multiple pages that inherit from this abstract page?
For some time now I am trying to figure out how I can refactor some of my code to reduce redundancy throughout my application. I am just learning the basics of OOP and can create simple classes and methods but my knowledge is limited in terms of practical applicability. The following bit of code illustrates my frustration:
[Code]....
This bit of code is used on several pages of my project in the pages codebehind file. How can I move this to a class file. I don't know how to reference an object like a gridview in a class because it does not exist like it does on the actual page.
if we can include a css class from code behind for a link button. I have been trying this since a while but I was not able to get it done. It does not show a hyper link nor css works. Please refer to my code and see where am I doing wrong.
string link1 = "google.com"
lblclick.Text = "<p>See what our page looks like by clicking "
+ "<asp:LinkButton CssClass="+"linkclass" + ">"
+ link1 + "</asp:LinkButton>
I have two classes (say someclass.cs and someclass.generatedcode.cs). How do I make the someclass.generatedcode.cs inside of someclass.cs (something like a code behind) in visual studio?
