Web Forms :: Timer Executes Page_Load That Should Execute Javascript Function But Does Not Work?

Feb 10, 2011

I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes

a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I havent put here.

But what does not work is the code I have in the Page_Load event now.

I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");

This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.

But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve this?

AJAX :: Execute JavaScript In C# Code?

Mar 10, 2011

Basically i have two asp.net buttons on my asp.net page as follow:

[Code]....

and this is the code behand fo btnSave onclick event:

[Code]....

and this is the code behand of btnPreviwe onclick event:

[Code]....

as you can see, when the btnSave is clicked, it is programmatically clikced the btnPrevew first, and btnPreview registers and fires the required JavaScript. But actually once the btnSave clicked, it does go to the btnPreview_OnClick event, but for some unknow reasons, the javascript in btnPreview_OnClick doesnt work, however, when i just put cstext2.Append("alert('hi')" instead of cstext2.Append("'SaveSignature()'", the javascript does executed, and also if i modifed the asp.net code for btnPreview to this, it works too.

Javascript - Execute Some Custom Code Before AJAX Request Is Sent

May 10, 2010

I have a drop down in an ASP.NET page. Whenever the value of the drop down changes an ASP.NET AJAX request is made to the server. I also attached a jQuery "change" event handler to that list to execute some code when the value is changed. So, probably two different event handlers are being attached to the same drop down, and it's causing some problems, i.e., sometimes wrong drop down values are sent to the server. I don't know why is this happening but I think attaching two different event handlers to a same drop down may be the reason.

Can anyone tell me what is the problem here? If what I guessed is true, then is there any other way to execute some custom javascript code before asp.net AJAX request is sent ?

Web Forms :: Execute Server-side Code From JavaScript?

Jun 11, 2010

Executing Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Execute JavaScript From Code - Behind After UpdatePanel Has Finished Loading Its DOM Elements?

Jul 7, 2010

I have an UpdatePanel with a repeater in it that is re-bound after a user adds an item to it via a modal popup. When they click the button to add a new row to the repeater the code-behind looks something like this:

protected void lbtnAddOption_Click(object sender, EventArgs e)
{
SelectedOption = new Option()
{
Account = txtAddOptionAccountNumber.Text,
Margin = chkAddOptionMargin.Checked,
Symbol = txtAddOptionSymbol.Text,
Usymbol = txtAddOptionUsymbol.Text,
};
Presenter.OnAddOption(); // Insert the new item
RefreshOptions(); // Pull down and re-bind all the items
mpeAddOptionDialog.Hide(); // Hide the modal
// ... Make call to jQuery scrollTo() method here?
}

This works fine and the new row will show up quickly via the UpdatePanel. However, there are often hundreds of rows and where the new one is added is based on the current sorting column used. So, I wanted to take this as a chance to use the sweet jQuery ScrollTo plugin. I know that if I give it the ID of my overflowed container div and the ID of an element within it, it will smoothly scroll straight to the users newly added row. However, there are two problems:

I need to find the appropriate row so I can snag the ClientID for it. I need to execute the jQuery snippet from my code-behind that will cause my newly updated repeater to scroll to the right row. I've solved #1. I have a reliable method that will produce the newly added row's ClientID. However, problem #2 is proving to be tricky. I know I can just call ScriptManager.RegisterStartupScript() form my code-behind and it will execute the JavaScript on my page.

The problem I'm having is that it seems that it is executing that piece of JavaScript before (I'm guessing) the newly refreshed DOM elements have fully loaded. So, even though I am passing in the appropriate jQuery line to scroll to the element I want, it is erroring out for me because it can't find that element yet. Here is the line I'm using at the end of the method I posted above:

string clientID = getClientIdOfNewRow();
ScriptManager.RegisterStartupScript(this, typeof(Page), "ScrollScript", String.Format("$("#optionContainer").scrollTo("{0}", 800);", clientID), true);

What do I need to do so I can ensure that this line of JavaScript isn't called until the page with the UpdatePanel is truly ready?

Binding Javascript Keypress Events?

Nov 22, 2010

I have a need to monitor the state of the Shift key, whether it is up or down. Its purpose is to notify the user that while the shift key is held down, the drag and drop operation they are about to perform is going to COPY the node(s), and not move them.

I have it working perfectly with the code below, however, if I hold the Shift key and perform the drag and drop, the hook no longer exists; the screen no longer responds to the key press and remains in the "pressed" state.

<form id="form1" runat="server">
<div>
<table>
<tr>
<td valign="top"><ASP:Literal id="treeLeft" EnableViewState="false" runat="server" /></td>
