Onclick Message Handling On A Webpage Button?
Feb 24, 2010
I have a button on a webpage that has the following added programmatically to its "Attributes" property.
btnDeleteNode.Attributes.Add("onclick", "if(confirm('delete this node?')){}else{return false}");
This works fine but now I need to check to see if the user has selected a node in a tree before asking if they want to delete it. If a node isn't selected I need to tell the user to select one. My question is, can I do this using the above method (I don't know java script) or should I use a different approach ?

I have what is probably a basic question, but I am rather new to writing exception handling code. I thought I understood the concept, but apparently I don't, heres the code:
[Code]....
If I enter in any non-integer values, the textbox is set to nothing and the label displays the error message. However, now that I have verified the textbox contains an integer, I want to continue on and use that value. The remaining code works fine unless there was an exception, in which case the conversion to an int value for x throws an error.
All the examples I have looked at demos the structure of try-catch-finally, but in this instance I am not performing any clean up, I want to execute code when a valid value is entered into the textbox.

Obviously I am a total noob and this is simple to some of you, but I can not figure out why the rest of the sub works, but the button1.Text="Uploading, Please Wait..." seems to be completely ignored.
The button is supposed to change text when clicked but no method I have tried works with my page.
Here is my simple upload form page:

I am working on a financial portal and I am having a problem..I don;t know what to call it so i mentioned it as an 'unknown to me' problem..I have a webpage..whenever I click on any button on my webpage, the request goes through..but nothing show up on the webpage..then If I click on another link and then again come back to previous link,then only I see the results of button_click..
e.g.
I have a currency conversion and investment form..so after filling up the form in following way and if I click on "INVEST" then nothing shows up..
so now if i click on any other link and go back to 'buy currency' link I see the result as 'investment successful'

I am returning a simple string from a webmethod to a Javascript function.I am using an AJAX enabled website in ASP.NET 2.0. I get the date in firefox but inside IE 8 it returns undefined.Do I have to parse the string in the JSON format using some serialize class? In my webmethod, I am just using:
return DateTime.Now.ToString();
$(document).ready(function(){
var pageUrl = '<%=ResolveUrl("~/test/test.aspx")%>';

I am hoping to upgrade the below two classic asp web pages to an asp.net web pages. The pages basically perform actions on incoming query string variables and also the login_fail_license.asp page sends us an email to inform us of certain situations. Currently they're a bit dated and I'm hoping to upgrade them to c# so I can fully understand what they are doing as we have been receiving strange IP addresses against our own license numbers (5000), I think the logic maybe wrong.

I have an asp:button with an onclick property that posts back to the server. I would like to do some validation on the contents of a textbox before I fire the postback. I want to do the validation in javascript using some regex.I cannot use an asp:XXXXvalidator; I just can't due to what my web app does.Is there a way to call a javascript function from an asp:button that then calls the postback? I know I can use OnClientClick to call js from the asp:button, but once I call the JS how do I signal that I want to postback the button?

I have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?

I have a button on an ascx control that calls a method on the onClick event:
<asp:Button id="bUpdateText" onClick="FUpdate" ValidationGroup="Update" CausesValidation="False" Text="Update" cssclass="button" runat="server" />
Normally I use this control on it's own page and the button works. This time round however, I am loading this control into a Div that is present on the home page of my site (that way I can show the contents with a little bit of JQuery). However, when I bring the control in this way, the onClick event doesn't fire and I am not sure what could cause that.
I don't have any code sample but the nature of the site makes it difficult to provide any that would make sense.
In short, what would stop this event firing now?
p.s I have tried adding validation groups to all other buttons and validation controls on the page and there is only ONE form present on the page.
EDIT: I have only just added the validation stuff in to see if that does anything. By default it has been like this and still didn't work:
<asp:Button id="bUpdateText" onClick="FUpdate" Text="Update" cssclass="button" runat="server" />
As mentioned as well, this works when I use this control on it's own page (loaded directly into Default.aspx) so I don't think the case of onClick matters.
EDIT2: I have just noticed that when I click this button, other validation controls on my page are being triggered even though they have their own DIFFERENT validation group?!

I have a ASP.NET (C#) web page in which I want to enumerate a dictionary in a code render block:
<% foreach (Dictionary<string, string> record in parsedData) { %>
<div>...Some HTML Code...</div>
<% } %>
But I get an error like:
Compiler Error Message: CS0246: The type or namespace name 'Dictionary' could not be found (are you missing a using directive or an assembly reference?)
How do I import System.Collections.Generic into the page itself? Here is my page directive:

I would like to add an Onclick event to one button (ShipEdit is the name of the button), I would like to redirect user by clicking this button to new page that is (../Account/MyAccount.aspx) and send 2 variables that is (LineItem.LineKey and shipment.ShipmentKey) with the URL: I need to write a code in this module:
void repShipments_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
I have tried to use this line of code but it does not working.
ShipEdit.Attributes.Add("onclick","ShowPopUp(" ../Account/MyAccount.aspx?LineKey={0}&ShipmentKey=",true);",LineItem.LineKey,shipment.ShipmentKey;
I am not sure how writing it with the ShipEdit.onclick, it gave me error anything that I tried.
