View 5 RepliesI only want to execute this JavaScript function runEx() if publicVarFromCodeBehind != "abc".
I am setting the publicVarFromCodeBehind = "abc" in the Page_Load event but anyway the runEx() function is executing. I wonder how this works and how to prevent runEx() from executing though I need to catch the logic from C# and pass on the variable to the JavaScript.

how to execute the code behind function using JavaScript keypress ?
The reason is that the keypress that I'm referring to will be used in searching record so I want that every keypress a result will be shown in the gridview immediately.
I have created javascript function as mentioned below to hide/show some control. I am calling this script on dropdown on 'onchange' method. In dropdown first item is "-- Select --".

How do I execute a function in JavaScript when a text box is populated with text? The text box with be hidden from the user. It will be populated by a USB magnetic card swiper.
Pseudo code:
<script language="javascript" type="text/javascript">
function MyFunction() {
//execute this function when MyTxtBox is populated
}
</script>
<asp:TextBox id="MyTxtBox" runat="server" Visible="false" />
How do I execute an JavaScript function right when an ASP.NET text box control is populated and focus is still set? The onChange event will not work because I need to programmatically move focus to the next form element after the JavaScript function has executed.
Is is very similar to this question. The marked answer is correct for the context on the question, but after some more testing it did not exactly solve my current issue.

I need to execute a javascript function when a row of a datagrid is clicked. I am not sure how to do this.
I have tried adding a template column with a button
<asp:TemplateColumn>
<ItemTemplate>
<asp:Button
ID="myButton"
Text="Insert
collection"
OnClientClick="putData();"
runat="server"
/>
</ItemTemplate>
</asp:TemplateColumn>
And then attaching the javascript to it:
myButton.Attributes.Add("onclick",
"putData()")
But it produces an error.
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 haven´t 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?

I have Asp.net mvc project I am new to this project. help me out step by step to catch the Errors in Controler class and Log those errors. what I did here is.
1) Using Enterprise Library 5.0 I configured the Loging and Exceptoin handling.
2) I wrote This Method In ControllerBase Class( please correct me if I am wrong)
protected override void OnException(ExceptionContext filterContext){ // Bail if we can't do anything if (filterContext == null) return; // log var ex = filterContext.Exception ?? new Exception("No further information exists."); LogException(ex); filterContext.ExceptionHandled = true; var data = new ErrorPresentation { ErrorMessage = HttpUtility.HtmlEncode(ex.Message), TheException = ex }; filterContext.Result = View("Error", data); base.OnException(filterContext);}
what do I need to do catch the Controller Error.. How OnException will Execute when some error happens in controller? do i need to code anhything in controller?
4) where do i need to check this Log Information? how?
5) is this OnException Method I wrote like I created One Class and Inherted from Controller class something like this
Namespace ......... : Controller
I wanted to create a CurrentUser object to be accessible in every Action of Controller, I initialized it in Constructor but User.Identity was not available in Constructor. I followed the following link on stackoverflow:
Defining a User with User.Identity.Name in controller constructor
But after inheriting my Controllers from BaseController, my Action methods are not even executed, the execution stops at Execute of BaseController and I get blank pages in the browser.

I am developing a remote control application where a client (aspx page in a browser) can request a server to "launch a notepad" (for testing purpose, for real life, turning off a light bulb, etc). So I created a dll with a simple function for launching the notepad (on the server side) and dropped this dll in the root bin folder.
It worked fine when the aspx page is running under ASP.NET development server (launched from Visual Studio). But when I tested the same aspx page under a FireFox browser, it did not work (launch the notepad) even though it did call for the same function (I stepped through in debugger).
Is this a permission issue? How do I set this up in IIS manager, or even better in web.config?
1. How can I create a delay in C#.I know Thread.Sleep(0) but it is blocking my GUI.2. Also I need to pause the execution of the normal flow until a function return a result.
View 13 RepliesI have a page with some custom validation which displays a result in a validation summary. I would like to reposition this validation summary to the bottum of the page without causing the page to scroll with the length of the validation summary. I have a jQuery function which does this very nicely, however, I need to execute this jQuery after the validation summary is displayed and i'm not sure which event to trigger.
$(document).ready(function(){
$("#<%= vsmSummary.ClientID %>").change(function(){
var newTop = $(window).height() - $("#vsmSummary").height();
var newLeft = ($(window).width() - $("#vsmSummary").width()) / 2;
$("#vsmSummary").css(
{
'position': 'absolute',
'left': newLeft,
'top': newTop
}
);
});
});
In my custom validation method I build this string and register with the RadScriptManager...
Dim scriptText As String = "$(document).ready(function(){ " + _
"$(""#<%= vsmSummary.ClientID %>"").ready(function(){" + _
"var newTop = $(window).height() - $(""#vsmSummary"").height();" + _
"var newLeft = ($(window).width() - $(""#vsmSummary"").width()) / 2;" + _
"$(""#vsmSummary"").css(" + _
"{" + _
"'position': 'absolute'," + _
"'left': newLeft," + _
"'top': newTop" + _
"}" + _
");" + _
"});" + _
"});"
RadScriptManager.RegisterClientScriptBlock(Me.upSCPPage, Me.upSCPPage.GetType(), "DynamicVSM", scriptText, True) This works!! I had no clue that I could call this from my code behind!! I will be doing this much more in the future!

I'm developing a web application that displays items from a work queue to a user. When an item is selected I have the app lock that item out so no other user can select it. By hitting the back button in the app it unlocks the item.
I want to be able to unlock the item if the user hits the backspace key. I know what code I need to unlock it. I just need to know how to make the code execute on backspace key stroke.
I'm creating a HyperLink dynamically in my code behind based on a database table. What I'd like to do, is that whenever someone clicks the link, a function is executed that then does some processing before rerouting them to the linked page.
Is there a way to do this? I don't want the look of a button, even though I suppose that's the functionality I want.
I have a page that calculates some stuff and then displays it to the user. Because the calculation part takes a while I would prefer to have the entire page load with empty data and only after that call the calculation and the display data function.
