Web Forms :: Disable "enter" Click On Imagebutton?
Sep 14, 2010
When i press "enter" i dont want the first button that is on my page getting fired.
This is a imagebutton. I did try with a javascript function that checks the event keycode but this always returns 13.<script language="javascript"> function noEnter() { if (event.keyCode == 13) { return false; } } </script>
When i add OnClientClick="return false;" then you can't press the button at all.<asp:ImageButton
ID="backButton"
runat="server"
CausesValidation="false"
ImageAlign="AbsBottom"
ImageUrl="../../images/Global/back.gif"
OnClientClick="GoBack2_Click"
OnClick="GoBack_Click" OnClientClick="return false;"/>
When i click with the mouse on the button the Goback function does not get called.
So what i'm trying to get here that the imagebutton need to be clicked with a mouseclick and not with and enter keystroke.

OK, been burning up Google and Bing trying to figure out a good solution to this problem, and so far, I feel like I've taken a dive down a rabbit hole - I'm just waiting on the Queen of Hearts and the Mad Hatter to show up. Alice is kinda cute, but unfortunately, she didn't have any good suggestions, either.
Here's the scenario - I have a User Control on a Child Page that has a Master Page assigned. The control is for logging in to the system, so it contains two text boxes, a couple of links to password recovery and registration, and an ImageButton to handle submission of the username/password entered in the text boxes.
Everything works just as expected when the user actually takes the mouse and clicks on the ImageButton control.
Things don't work so well when the user enters a username and password and then presses the Enter/Return key.
While debugging, VS2005 (I know...ugh!) will stop at the LoginButtonClick event, and seems to run the code. Of course, the .Text property of the two input controls was empty, but the Request.Form collection had the values burried within the collection of Keys.
So, a little bit of digging got me to the point where they can login using either the Enter key or clicking on the ImageButton. So, everything seems like it's good, right? Nope, not so fast.
When I enter a username/password combo that's designed to fail authentication, the code will step through setting the error message, etc, but that information never makes it to the point where it's visible to the user.
I'm not seeing any extra postbacks (obvious ones, anyway), but for some reason, when the page goes to redraw when it's in a "failed" state, the notations just simply aren't there.
Below is the code in the User Control that handles the actual authentication routine. All controls, such as the Label with ID "message", are local to the User Control, so I don't think it's a FindControl("message") problem or something similar...just so bizarre that it disappears seeming without reason.

I have an ASP.Net page with a usercontrol on it. The submit button for the page is within the usercontrol. There is an ImageButton on the page itself (outside of the usercontrol). Whenever I hit the enter key to submit the form, it always executes the ImageButton click instead of the submit button within the usercontrol.
I'm using a MasterPage for the style, so the form is within that which rules out using the form's DefaultButton property.

I'm using a ModalPopupExtender to display a login screen when an ImageButton (called Post) is clicked.The dialog pops up as expected and performs all the correct validations. When the user presses the Enter key, this causes the Login button to fire its Click event as it should.The issue I get is that I have another ImageButton on the main page. After the user presses Enter in the login and the page logs the user in, it does not fire the server click even for the initial post button that brought up the login, it fires the click of another ImageButton instead.

There are a lot of post about how to disable the Enter key in a one-line Textbox, but non of them works if you put the Textbox inside an asp:panel.I assume there are multiple eventhandlers on the keypress event on a Textbox if it is inside a panel. So I would have to add my own handler at the end of the list somehow.

I have developing ASP.Net Website and has a Webform with lots of controls. I have so many different controls on my page like buttons, textboxes, etc.
Now what happens is that generally on any form, when user hits Enter Key, it fires the first default button's click event or if focus is on any button, it fires that button click. I want to avoid this.
When user hits enter key on form basically nothing should happen. But let's say if he is entering into multiline textbox, that enter key should work to go to next line in that textbox.
I tried this.
[Code]....
but the problem is that then it disabled enter key for everything. But what I am looking for is that to avoid any button click event or any other postback to happen when user hits enter key while being on form anywhere. But Enter key should work when it is inside textbox or inside any such control.

I know this question has been asked before. But for some reason I can't find the exact answer I need for my problem. My problem is as follows:
I am creating a web page (The one posted is just an easy example) that creates multiple ImageButtons on one page via a loop.I have tried many other ways (for example, create instance in form_load and pass to the WriteHtml() method) but I can't figure out a way to complete this. In this example I have 10 buttons that need to be able to be clicked.
The code is as follows:

I have a gridview that has a column with an imagebutton. That image button event calls my update procedure and merely updates that records status and when the gridview rebinds, the image changes and is no longer available.Whats happening is if the page is refreshed, the update occurs again. If i add this around the update code, works great the first time, but then any other updates are ignored.. is there anyway to know wether the page was refreshed vs actual imagebutton postback?
if (!IsPostBack)
{
}
Since the update is just setting a flag for that record, on another page that displays those records for a seperate department. IF by chance the first page is still open and the 2nd department resets the flag, if the first page is refreshed, that flag is reset again. so its creating some inconsistant results..

I want to put five buttons: introduction, product, history, feedback, contact. And when I click any one button, that button became dark blue, and others remain, no changes. So I write the following code:
Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION BLUE.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton2_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton2.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS BLUE.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton3_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton3.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY BLUE.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton4_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton4.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK BLUE.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton5_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton5.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT BLUE.jpg"
End Sub
It is workable, however there is only one problem: when i debug it some times it is ok, but some few times the button suddenly became small.

I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

I'm sure this has been asked before I just did not know how to ask it to get the forums to show up the right answer. I have a master page with a search box and then a content page with an input box and a submit button. As I'm using the program, I as a keyboard lover always hit enter after typing text into a text field. The issue is that when I'm typing in the input box and I press enter, the search boxes button will steal this enter. How can I divide the two asp.net form elements so that when I'm typing in the search box and press enter, the search button is invoked and when I'm typing in the input box and press enter the input button is invoked? An example of this happening is in the code below
