How would you call a Javascript Function from CodeBehind on Page Load event without : Ajax (ScriptManager), Response.Write ?
View 2 RepliesMy javascript that scroll down the page.
function SetScrollEvent() { window.scrollTo(0, document.body.scrollHeight);}
I update update panel from server side like below.
protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e){
//HiddenField hiddenId = e.Item.FindControl("hiddenId") as HiddenField;Label lb1 = e.Item.FindControl("Label2") as Label;
//Button bt = e.Item.FindControl("Button2") as Button;if (e.CommandName == "myclickevent"){
// your codes here...SqlConnection conn = new SqlConnection(constr);SqlCommand
[CODE] .....
I use repeater and repeater have button on button click i update the update panel. now where i have to call the javascript function so that it execute after update panel fully loaded. I want to call javascript function after page fully loaded.
I have some code I only want to execute the first time I display a form. With this in mind I created a class variable which I initialize the first time I execute page load.
public partial class CLVideoDefinition : System.Web.UI.Page
{
string videofile;
string first;
protected void Page_Load(object sender, EventArgs e)
{
if (first != "N")
{
I then select a value from a drop down list , but when it does the auto postback it executes page load but my class varaible has been reinitialized to null and will then execute the code I only want to execute on the first run. why my class variable has been reinitialized.
On the page load i wanna call a custom validator which validates my page and display corresponding error messages.
How can i do this?
I am using javascript in the custom validator.
I have a confusion regarding ajax call.when an ajax call is done why is it so that a page load event is fired when its not a ful page request.
My understanding is that a page load event should not be called on an asynchronous postback.
Can any1 explain me why this is happening?
here is the code:
aspx page:

I have a list of items that loads when I call the page controller and I have an Ajax.BeginForm that calls the same (Index) Action. If the Action sees that it's an Ajax request (Request.IsAjaxRequest()) then it returns a partial view. I even have a div that contains a message about the results loading. That all works fine, but my results can sometimes take awhile and I'd like to hit the page first and then make the Ajax request so the user sees the page quickly and sees the "loading" message. I know I could click my filter button (triggering the ajax call) using jquery on document.ready, but is there a more MVC way to do this?

I have a set of links that exist in the master page. I have a css class i would like to assign to a particular one of them depending on if that is the page you are at during page load. ex: Home will have the current_page_item class if you are at the index page
This is what I have:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DirectCast(Me.Master.FindControl("ctl00_homeLi"), HtmlGenericControl).Attributes.Add("class", "'current_page_item'")
End Sub
I have a MasterPage project which is a class library project (it includes themes, style sheets, menus etc) and all applications use them.
I am using the BasePage concept for dynamically adding title,meta tags and descriptions. This BasePage Class inherits system.UI.Page and the aspx pages in the project inherits the BasePage class.
Now i need to move this BasePage class from my application to the Master Page Project so that all the projects/applications can reuse the same code.
I tried add the basepage.cs in the App_code folder and tried calling it in the page directive like below
<%@
Page
Language="C#"
MasterPageFile="~/Master/Layout/MasterPage.master"
AutoEventWireup="true"
CodeBehind="xxxx.aspx.cs"
CodeFile="xxxx.aspx.cs"
Inherits="xxxx"
ValidateRequest="false"
EnableEventValidation="false"
ViewStateEncryptionMode="Never"
CodeFileBaseClass="~/Master/App_Code/BasePage<Page>"
Title="Title"
Meta_Keywords="xxxx,yyyy,zzzz"
Meta_Description="This is a test" %>
But i am getting error
Could not load type '~/Master/App_Code/BasePage<Page>'.
This was working fine till the BasePage class was inside the application. But once i moved it out of the project and added it to the master page project i getting this error.

I have a WindowsForm that has a DataGridView that shows output of my app. The class with the button is DriveRecursion_Results.cs.

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
I got a ASP.Net website (webforms application in C# - .Net framework 2.0) with Master Page, webforms and a GlobalFunctions class in App_Data folder where i do have ErrorLog functions and few other generic functions. Everytime an exception is caught in my webform it calls this GlobalFunctions.Errorlog function to log the error in my database table. After the exception details are written to the database table, I also would like to redirect the user to my ErrorPage.aspx like
Response.Redirect("ErrorPage.aspx",false);
However since i am inside a class (GlobalFunctions.vb) and not a webform, I don't know how to redirect this to ErrorPage.aspx since i can't access Response class.
