Button Clicked Twice Before Postback?
Oct 14, 2010
I have a url whose query strings are concatenated based on selected items on a form, I need to do a post to this url, but an imagebutton control has to be clicked for the post to occur. I put the PostBackUrl property of the imagebutton inside the event of the image button, hence causing it to be clicked twice before eventually posting the url... but i really need to click once but this aint working. I know why its clicking twice, tried calling the url with javascript but it wasnt working.

I have two text boxes txtBox_Input1 & txtBox_Input2 which Iam trying to validate on a postback when a button is clicked.here is the code:
[Code]....
The issue is that its causing an unhandled exception. When i debug by applying breaks and i check the validatorControl.ControlToValidate the IsValid property is false and then i try to cast the ControlTovalidate which is a string to a TEXTBOX and try change the border properties i get NullReferenceException, i.e. errortxtbox control is null at step '3->'. I check the validatorControl and I have all the attributes there but somehow its not casting the controlToValidate string as an appropriate texbox control to errortxtbox.

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'm having some trouble with jQuery UI. I've created a dialog with jQuery UI: so far, so good. I set up a form inside the jQuery UI dialog and then it's another story. I've written a very simple page to illustrate:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testpage.aspx.cs" Inherits="RiverCascade.testpage" %>
<head runat="server"> [code]....
In the code above, see that I've just imported the jQuery, jQuery UI, and stylesheets and set up a page with a dialog box. There is an asp control button1 outside the dialog box and an asp control button2 inside the dialog box.
When I click on button1, the event handler gets called and all is well. However, when on click on button2, the button inside the jQuery dialog, nothing happens.Why is my web page behaving this way?

I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"

A user sees a page with a button. When he clicks the button a paragraph of text shows up above the button. With each click, another paragraph of the same text shows up.
Can this be accomplished with a view, partial view, standard button, and without JavaScript?
