Adding OnClient For A Button?
Apr 15, 2010
i've added the next line to show a confirmation window after clicking on a button.both the button and the adding is done in the code-behind :
Button B2 = new Button();
B2.text= "whatever";
B2.Attributes.Add("OnClick","return confirm('Sure about that?');") ;
And i've got the button's OnClick event handler working, but for some reason, having the confirmation dialog disables the postback.
I've tried- B2.Attributes.Add("OnClick","PostBack: True") ;
But this will overwrite the first Attributes.Add...

How do I do this? Basically, next to the page numbers in the GridView I want a link button to disable paging. This works, but I want the button inside the footer of the GridView, next to the page numbers.

I have a calculator page that calculates the carbon footprint of electricity and water, which has two textboxes and two drop down lists and a button.
When a user enters a number in the two text boxes, each number is multiplied by the other number given in the dropdown list ,and then clciks on the submit button he/she gets the result in a label as well as the values he entered.
what I need to do is enable the user to add another calculation in the same form and i need the label to keep the result. so, the user can enter new values in the form as the fields will be cleared and clicks on the calculate buttin again, gets the result and the total result is added to the previouse one.

I'm having an issue with trying to add a button to my grid. My GridView is first loaded with data in the PageLoad event.
I'm then taking the data in the first cell of each row, and creating a button that will link to a URL. To get the URL, I have to run a query with the data in the first cell as a parameter. I was doing this in the RowDataBound event at first, but hitting that query for every row was making it really slow.
So I decided to add a button that would retrieve the URL only when you clicked the button.
Here's my GridView:
[Code]....
The grid generates fine, the button gets added to the grid for each row. But when I click on it, the RowCommand event doesn't fire, and the page just refreshes.

What is the best solution for adding Textbox controls dynamically to a page when a button is pressed?
The secnario is: "The page initially loads with 3-4 textboxes already displayed but the user needs another textbox added. They click add textbox and another textbox control appears."
I would hope to be able to do this within a updatepanel and use AJAX async postback.

I just want to add and attribute called "pubID" to an image button with the value I give it and then call that value on the image button click event. This image button was created dynamically as well. At the moment this code is not working. When debugging it looks like Pubid is getting assigned a value but on the click event, the attribute isn't being retrieved correctly.
--added attribute

May seem like an easy question, but can I add a URL to submit button -
Other than using Response.Redirect ?
Further Info: What i'm trying to do is a lighbox control to a button which fades out the screen and forces them to read a warning message.This would work in HTML like this:
< a h r e f =" images/image.jpg" rel="lightbox"> link < / a >
but using response.redirect doesnt work:
Response.Redirect("lightbox/images/image.jpg?rel=lightbox")
(as it opens up the image in a new page).

I'm just starting out with ASP.NET and I'm not sure how to go about the following:users have to input a part number into a text field. Sometimes they only have to input 1 part number, sometimes 50. I want to have 1 text field where they input the first part number, and if they have another one, they press a "more" button. Then, a new text field appears right beneath the first one. IF they have more part numbers, they just press the more button again... Is there a way to do this? If so, can someone give me any tips or hints on how to approach this?

I have basically something like this:
<asp:datagrid id="DGrid" runat="server" AutoGenerateColumns="false">
<asp:TemplateColumn HeaderText="Stuff">
<ItemTemplate>
<asp:PlaceHolder id="PH" runat="server" />
</ItemTemplate>
</asp:TemplateColumn>
</asp:datagrid>
I need to add a Button to the PlaceHolder depending on the values of the data I am binding. At the moment I am adding the Button after the data is bound in Page_Load. The problem is that the data binding methods are not called in postbacks, so the Button disappears when I click on it.
Problem is that I need to know some attributes of the grid item to create the Button, so I cannot create it before the data has been bound.

I am having trouble with something, my client wants to be able to hit <enter> as well as click the button on this page:-
[URL]
If you look at the Blue "Postcode search" and try searching for a nursery byb clicking the button you will see how it works. However then try doing the same but hitting <enter> and see what happens..
The front end html is as follows:-
PHP Code:

I tried adding javascript so it would recognize the button and allow users to hit enter but this did not work.

I have gone through several posts on this forum about adding a linkbutton to an updatepanel dynamically. A lot of them say just give it a unique ID and some say you have to register add an AsyncPostBackTrigger to the triggers collection. I have tried both and neither work. I have this simple test that I created - the code is below - there is nothing else in this project but the code you see so I know nothing else is interfering with it.
I have also seem people complaining that the linkbutton causes the entire page to postback - in my case nothing happens... I have seen people talk about having to add the triggers on the page init however I can't do that - I am dynamically creating menus based on a selection in a listbox... (not in this simple test but in a larger project) I am using Visual web developer express 2010 if that makes any difference.

I have an upload control inside a panel and I am wanting to restrict the file types. I have found the following regExp but I'm unsure where to put it?
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.doc|.PDF|.gif|.jpg)$"
Does this go into the 'ValidationGroup' within the upload button?

I just don't understand how this is done. I've gone through several questions here and from a few other websites.
Basically, a company will be adding process steps, and I want there to be a textbox with a button next to it that reads "Add another step." Once clicked, a new textbox will appear beneath the current one, and the button will be moved next to the new text box. What do I need to do?

I know a little bit of vb.net but don't know all that much about the asp.net technology. I do some volunteer work for a non profit organization and what I'm trying to do is integrate an image gallery into their site, instead of using an external image service that they use now.
After some searching I found an easy to use program that automatically creates the necessary thumbnails in a table.
However I want to add some functionality; when a user clicks an image for full size I want to add the option to click a button or link, to get to the next image.
I've done a lot of searching but couldn't find how to achieve this. I guess I need to find out the current image and then somehow jump to the next image.
How to implement this. Preferably I'm looking for something that is easy to implement. I'll have a number of different albums with a different amount of images. If possible I'd like to avoid having to rename the images so that they are photo1, photo2 etc.
Currently the image gallery looks like this : [URL] ....
I'm pretty sure I will need to make some changes to the viewimage.aspx file. Currently it only contains:
vb Code:
<img border="0" src="<%=Request.QueryString("img")%>" alt="" />
Not sure if you need to know the code that does the thumbnailing + creating clickable thumbnails, but I'll post it just in case it's needed
vb Code:
<script language="c#" runat="server"> void Page_Load(Object sender, EventArgs e){
// Modify these numbers for the thumbnail size you want const int maxWidth = 200; const int maxHeight = 200;
ArrayList pics = new ArrayList(); string html; int imgHeight; int imgWidth; foreach(string s in Directory.GetFiles(Server.MapPath(""), "*.jpg")){ System.Drawing.Image currentImage = System.Drawing.Image.FromFile(s);
[Code] ....
I got the code from here: [URL] ....
but the contact button doesn't work, otherwise I would have contacted the original author.

I have a web page that contains a couple of button controls. The page is pretty simple, just trying to add a record to the DB. When I click the Submit button, every function/procedure that is supposed to be executed does execute except the Button Click Event. I've checked to make sure all occurrencs of the control are named correctly in the code-behind as well as the javascript. I've set the debugger to debug every function/procedure as well and nothing happens. Why this would occur.

I need to be able to print a friendly version of the page I am working on. I have done the CSS page for it and it works. However I would like to add a button that the user can click to print. Now i know that some browsers may not allow the button to work, but i know you can use javascript to do it. Any way that it might work other then javascript or selecting file/print. I would like to bring up the print dialog box if i can but not that important.
