and when I click my button, it is disabled for 1-2 seconds and automatically enabled, but I am not sure why it is enabled. I didn't add any part for it to be enabled again.
If I use both onclick() and onClientClick() can I make sure that server side will be called only after client side function returns TRUE or vice versa?
For example:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Import Namespace="System.Xml" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <% protected void save_n_display(object sender, EventArgs e) { // This must be called when validate() returns true... } %> <asp:Button ID="Button1" OnClientClick="validate()" onClick="save_n _display" "Text="Check" runat="server" /> <script type="text/javascript" language="javascript"> function validate() // client side Validation is done { } </script>
So can I use onclick() and onClientClick() or do I need something different for this? I even tried passing variables from javascript to asp functions so when validate returns true then save_n _display will be called.
I have an imagebutton with an postbackurl and an onclientclick script. When i added the onclientclick code, if my javascript validation passes (aka returns true), the page just seems to perform a postback (the screen just seems to refresh
I decided to change what JS functions Im calling now since calling Multiple functions definately wasnt helping. Here's my updated code. All Im doing now is validating a single textbox and returning true or false. Even this simple function is causing the postback URL to never get called. Could it have anything to do with the fact that Im trying to call a function to return a true or false?
I have a linkbutton whose onclick method does not fire after a jquery drag and drop, the onlclientclick does work. Y would the server side code not work only after a jquery drag and drop?
I've read that OnClick is executed on the server and onClientClick is executed on the client. Is it better to use OnClientClick to do something like close a modal popup?
If my understanding is correct then this would avoid a trip to the server to accomplish the same task. This would be great for something that doesn't need to make a round trip to the server and back.
I have a dropdown list, where when I select OPTION value a Textbox appears. The issue is that when, I submit directly the required filed errors gives me message for both ie for dropdown and Textbox. It should only give error for dropdown.
Second thing,
The textbox validation is not firing when submitted without any value in it.
Basically I am using a ModalPopUpExtender and it works fine, except that the OK button has an OnClick event that only fires when it is clicked for the 2nd time.. obviously i can progress with populating my OnClick event method for later on - its just annoying that a user has to click my button then ok in the pop up twice before they can get their intended result!
I am having trouble with two buttons on a page. I dragged them on to the page and then double- clicked each of them in order to create the OnClick events.
I added my code to the events, but when I click the buttons, their respective events aren't being called.
I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.
How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)
I wanted to disable a button after it is clicked and at the same time fire the post back event to generate a report. My first set of code did not work because soon after the button is disabled the page won't submit/post back. here's the first set of code which was not implemented. the onclientclick calls a javascript function which has these lines
its not working from client side alone after I disable the code behind attributes.add but when I check the view source the 2 pages are the samewhy am I not able to move the code from code-behind to design view?
From time to time i am getting this error when attempting to delete a file.
Exception Details: System.IO.IOException: The process cannot access the file 'D:galleryimagesUntitled-1.jpg' because it is being used by another process.
And the times i see it most is if i upload the image and then within seconds try to delete the image.
Got really strange Firefox issue. Using the Microsoft __doPostBack javascript function in web forms page. Used for tab control, we have got each tab click calling the __doPostBack function. Works ok on my dev machine with all browsers but got a colleague who has an issue if he leaves the page idle for circa 3 -4 minutes. After this delay if he selects a new tab which calls the __doPostBack function the call to theForm.submit(); just hangs and get requested timeout. No .net calls are seen in Firebug. The __doPostBack event is called just theForm.submit() function just doesn't execute. If he does not have this idle time works ok. It is also ok for him on all other browsers.
I set these setting below at the Web.config of my site And it still return me to the loginpage after about 20 mins I checked the Properties of the site at IIS and the time out is 660 However at the properties of the defaultWeb it's not 660 since it will influence all the sites and that I don't want
I have applied some asp validation controls on a page ,but on clicking Save button data is getting saved without throwing any validation . But as I am entering data for the next time and then click save button then it's working.
My Gridview sort is working only first time. My Gridview sort only first time when I click on any column
I want ASC > DESC
Again DESC > ASC
and Again ASC > DESC this way my sort should work
I have changed my code
I added Gridview binding to PAge_Load function
Code is below
Public Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim myUserInfo As GCS_User_Info = Session("UI") If Not Page.IsPostBack Then GRDView.DataSource = GetSortableData(String.Empty) 'System.Drawing.FontFamily.Families GRDView.DataBind()
The client side validation will work sometimes, and other times it will put out a JS error.Webpage error details

I have been struggling to get file downloads working for some time now. Files that are a few Mb or less don't seem to cause a problem but larger files stop after a minute or so. I have tried two methods so far and neither seems to work any better than the other.
First Method:
[Code]....
Second Method:
[Code]....
I am well aware that the default timeout for a script is 90 seconds, so in the page load event I alter this to 10000 seconds for both the above examples.
[Code]....
[Code]....
This makes absolutely no difference - and besides this the download does not necessarily stop after 90 seconds - it is usually somewhere around 90 seconds but I have witnessed it stopping after 120 seconds. I don't have anything set up in my web.config file for this as I don't want to set large timeout values for the rest of my site. Does anyone have what I need to do to get my files to download and not stop after a minute or two?
