I've created an update section of a page using Ajax panels with JavaScript as the trigger, following this great tutorial:
[URL]
I've got the page working just fine, but I run into a problem if I move the update panel and it's contents into an EditTemplate section of a FornView. I think this is because the JS I'm using can't find the Update Panel once it's in a FormView.
This is the JS I'm using:

View 1 RepliesI'm trying to enable a button through javascript when a checkbox is checked. This works fine in one of my pages, but on one page the button and checkbox in within a ModalPopup window, and there it doesn't work. How can I work around this?
javascript: document.getElementById('<%=okBtn.ClientID%>').disabled = false;
I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.
The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.
so how can I then, make this performance faster?
disable / enable An Ajaxifeid Button From Client Side (JavaScript)?
View 3 RepliesI am developing a web application for online bidding wher I want the BID button to disable itself, on all clients, whenever someone places a bid. What I need is some javascript to ping the site to check if a bid has been placed on the server, if so, then disable the button. I was suggested to use jQuery for this, use .ajax to query the server for the check. Then use a setTimeout javascript function to keep checking.I am not javascript expert at all so any tips would be greatly appreciated. At lease where to start. Also, will I need to record every single bid in database to achieve above?

View 3 RepliesI need to change a standard HTML Input button to a Link button but am running into problems because the existing
code calls a javascript function. The function basically does the same as the browser back button. When I add the code and
set the property runat="server" I get a "CS1026: ) expected".
Quite new to ASP,net (VS2010) so could be going about this the wrong way.

I want to show a message with 'yes' and 'no' button when some condition in codebehind gets true.. and if user click yes then a piece of code will execute other wise it will not.

I have a LoginView element in an Update panel and use JQuery to hide the div containing the update panel when the cancel button(Html) is clicked.
It works fine normally. However, when I enter an invalid password and there is an error message displayed, the Javascript attached to the Cancel button click stops firing.
[code]....
standard webcontrol:
<asp:Button ID="cb_btnSubmitData" Text="Submit data" OnClick="SubmitData_Click" runat="server" />
added this in the Page_Load eventhandler
this.cb_btnSubmitData.Attributes.Add("onclick", "addTextToLabel('message', '" + this.cb_btnSubmitData.ClientID + "');return true;");
and this is the javascript that is executed when the button is pressed:

I have a page with 2 update panels
UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand
UpdatePanel2 has gridview2.
There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels
The behavior I would like is:
1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.
In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?
i have a GridView in my page that is associated with the database table "Blogs", GridView is showing all the table data correctly, i have added a link button column in the GridView, which is not defined or constructed in the Database table... I want that when i click on the button against a row in the button column of the GridView, the B_Id column cell value is passed to the other page, and control goes to the other page.
my blog.aspx code is listed bellow:
<%@ Page Title="" Language="C#" MasterPageFile="~/MiniWebShop.Master" AutoEventWireup="true" CodeBehind="Blogs.aspx.cs" Inherits="MiniWebShop.Blogs" %>
I have a gridview that does a select statement against a sql database. What I want to do is have the data in the gridview refresh upon either hitting the back button or the forward button.
If the back button is pressed it should give me yesterdays data from the table. If I hit the forward button it should give me tomorrows data, at the same time i want the forward button to be limited to going forward only 5 days from todays date. I figure that I have to do this in a Updatepanel however I am unsure as to how to do this.
I have a aspx page where in I have made a form. There is a help button on this form.When I click on the help button I have created html code in Javascript.

document.getElementById("help").innerHTML =Message_Help ;

i have hide a button using the code above

Now i wanted to display the button, a error occurred The name 'document' does not exist in the current context. So how can i display the button using JavaScript?
I'm using Javascript to create a DIV element and open up a new page by using onclientclick. This works great. Now, I need to write to it from the server side and this element must be created before it is posted back.
How do I get the javascript to execute before the postback?
Currently, I have to press the button twice because the element doesn't exist to write too on the first click.
To be clear, I need this to execute before the "OnClick" of the button.
Update: It looks like the Javascript function is called before the postback but the element is not updated until I run the second postback.
Update: Unfortunately it is a bit more complicated then this.
I'm creating a div tag in javascript to open a new window. Inside the div tag, I'm using a databinding syntax <%=Preview%> so that I can get access to this element on the server side. From the server side, I'm injecting the code.
I'm thinking this may be a chicken-egg problem but not sure.
UPDATE!
It is not the Javascript not running first. It is the databinding mechanism which is reading the blank variable before I'm able to set it.

i have a regular asp:button. I am working in .Net 3.5. I've tried adding a js confirm to the button with the OnClientClick attribute as well as adding in code-behind and the result is the same. No matter what the user clicks in the confirm pop-up the form will not submit?? BtnDeleteSelected.Attributes.Add("onclick", "return confirm('Are you sure you want to delete?');"); The confirm dialog appears and if i select "OK" it still does not submit..
View 4 RepliesMy website has been created with a CSS/HTML frame work that has been integrated into an ASP.NET website. Inside of a ContentPlaceHolder, I have a simple login form. The catch is that I am using the onclick event of an image to submit the form. It normally works pretty straight forward, but this time I am having an issue.
<div id="login">
<form action="index.aspx" method="post" id="nothingForm" name="nothingForm">
</form>[ code]....
I have to stick another form before the real form to make onclick="document['loginform'].submit()" actually work. This should not be the case, of course, but I was unable to find any solutions to it on the web.
I need my page to work when JavaScript has been disabled. But my button is outputting onclick="WebForm_DoPostBackWithOptions...". When I set CauseValidation="false" it disappears but I need validation. In what circumstances is WebForm_DoPostBackWithOptions outputted?
View 1 RepliesI want to remove previously visited url from history in asp.net so that if user click on back button of browser user will not go in previous url.
Is there any other method than Window.history.forward()?
I have a form submit button that has asp.net validators hooked up to it. If I make a javascript function to change the text to processing on click it does not work. The button flags the validators and also causes the whole page to post back. Heres the code I have:
C#
protected void Page_Load(object sender, EventArgs e)
{
btnPurchase.Attributes["onClick"] = "submit()";
}
Html
<script type="text/javascript">
function submit() {
document.getElementById("ctl00_ContentPlaceHolder1_btnPurchase").value = "Processing";
};
</script>
My goal is to change the buttons text to purchasing onclick if the form passes validation, and then in my code behind it will change back to the original value once the form posts back.
