I have a master page with a search box and button at the top. This search functionality is taking over the "enter" key for all my web forms that use this master page. That is, if I have a login page that uses this master page and the user enters in their username/password and hits "enter", instead of logging in the user the system performs a search.
What's the best way to set up the default submit buttons. I could wrap everything in asp Panels and set the DefaultButton property, but that seems a bit tedious. Is there a better way?
use defaultbutton property of form or panel
<form defaultbutton=“button1” runat=“server”>
<asp:button id=“button1” text=“Same Page” runat=“server”/>
<asp:panel defaultbutton=“button2” runat=“server”>
<asp:textbox id=“foo” runat=“server”/>
<asp:button id=“button2” runat=“server”/>
</asp:panel>
</form>
As you have discovered default buttons can cause issues when there is more than one button on a page. I would take the Geeks suggestion but simplify it by removing the setfocus client script and extend it by adding the keydown event to both the search textbox and the login textboxes such that the enter key fires the correct button depending on if your user is using the search box or the log in box, or any other textbox you want to add the javascript to.
You can set focus on loading the page (in code behind if you like) to save the user some mouse work or tabbing if there is a sensible control for the user to start at, but otherwise the control the user is interacting with should determine the flow of the page and what the enter key does.
set focus on the text box ,
Page.RegisterStartupScript("SetFocus", "< script >document.getElementById('" + TextBox1.ClientID + "').focus();< /script >");
and then
In the keydown event for the last textbox you can do something like this:
If e.KeyCode = Keys.Enter Then
Me.Button1.Select()
End If
Rather than using javascript to manipulate the page you could put the search box and the submit button into an IFRAME on the master page. If the focus is in the iframe clicking will submit the search form, if the user is on your main form within the page they will submit the normal page.
The <iframe> src attribute points to a little self contained aspx page holding your text box and submit button which redirects to your search results form.
This is what we tried on our project which seemed to work. I changed the Search asp:Button to be an asp:LinkButton. I then added some CSS style to give it a background image to make it look like a button. LinkButtons are apparently not used by the page for determining which Button is the default action when pressing Enter. The sweet part was that LinkButton can still have click actions associated with them so I didn't have to change any of my code-behind stuff.

I have 2 pages.
Login page
Search page (after login)
On my search page, I have several input box (text, radio, checkbox ...) .
The problem is, when the cursor is at one of the input fields, and the user presses Enter, the browser send the user back to the login page.
I fixed this issue using JQuery to capture keypress event on input items. However I still don't understand why is this happening?
P/s : if you need to see my HTML code please comment. The code stays on my work computer with restricted access so I can't post it here, but I will type it here if necessary.
Place your input inside a panel and set the default button to your default control.
<asp:Panel runat="server" ID="pnlForDefault" DefaultButton="btnSearch">
<!-- your input -->
</asp:Panel>
Now why is going back - and why I show you this panel method.
1. Maybe because you all ready have this panel on your page with wrong default button.
2. The user can press enter either when its on a text box, but also at any time, but only when the focus is inside a text box can be actually redirect that enter to some control. So either you may have some other library that take action on enter, either you press enter when you are focus on go back button....

I have a user control with a delete button. When a button is clicked, an event fires which deletes a record from the database. Now, the control is placed in Default.aspx. The whole body markup of Default.aspx (including the user control with its button itself) resides in <form runat="server"> as required by ASP.NET. Everything works so far.
However, the problem is when I put some validation controls inside Default.aspx (meaning inside <form runat="server"> because otherwise the page will report server errors). When validation controls are added, the delete button in the user control stops working. Clicking on this button no longer triggers the event as before.
Now, I disabled event validation in Default.aspx using EnableEventValidation="false" directive. I am also including UnobtrusiveValidationMode = System.Web.UI.UnobtrusiveValidationMode.None; in the code behind file. However, none of this helps.
How do I fix this problem and make the button clickable?
Update:
I know for sure that the validation controls are causing the problem, because I only need to add EnableClientScript="False" to each of them, and the button becomes clickable. But I don't want to rewrite validation on the client side manually!
It turns out the PostBack cannot occur if the form is not IsValid regardless of what element causes it. As long as that element (button) is inside the form with runat="server"that is invalid, the posback will not happen.
A very simple workaround is to just make the Button in my user control bypass validation: CausesValidation="False" (thanks to this question).
Another solution and maybe a more efficient one, is to use ValidationGroup. This way, all TextBoxes together with the Submit Button will belong to one group, and those controls that do not belong to that group will NOT be validated. In fact, they might have their own ValidationGroup; this will avoid interference between different controls within one Web Form.
I have put sign out button in master page. I have a page in which I use that master page and I also have update panel in this page. When I click on sign out button , it does not work. When I use anchor tag it works but I want to use Button.
Thanks,
this might be happen if you are using requiredfield validations for some input fields. try
CausesValidation="false"
for the button control and check. hope this help you.
I had the same problem and I solved deleting the main div nested in the asp Content placeholder. For me all the controls inserted in the masterpage was freezed, buttons, dropdown box, all in other words.
I have an ASP.NET web application that is using RegularExpressionValidator controls inside of a user control. The user control is placed inside of a panel with an ajax:modal popup. When I click the link, it will open the popup displaying the user control.
What is happening is when I click the link to open the popup, it is throwing a postback and activating the validators before the user has any opportunity to type anything into the boxes. I need to be able to click the link, open the popup, fill out the text boxes, and submit. The validators should only run when the submit button is clicked. Any ideas?
setting the validators parameters on the load in the code behind of the popupbox might fix your problem
I have 3rd party user control (a captcha control), which has a captcha image, a text box within it.
I am using the above user control in my webpage. I have a 3 submit buttons on my webpage (Validate Captcha, Submit Page, Add User). When I click the Validate Captcha submit button using the mouse, I am validating whether captcha is empty and showing a javascript alert.
The problem comes when I enter the valid captcha text in the textbox and hit enter key when the cursor is in the textbox. The page just refreshes. I am unable to add keypress event to textbox and call Validate Captcha button event as I am using the 3rd party user control which I cannot modify.
Also, Page.ClientScript.RegisterHiddenField(...) will not work in my case as I have two other submit button inside the same page.
Only option left is to enclose these in panels and set default button.
Please let me know if anyone has any better options for achieving this.
Greetings! I too use alot of third party controls. The thing to remember about these controls, it that in the end they just emit HTML. This means you can use the DOM to access and attach event handlers such as onKeyPress. The trick is to identify how your control creator named the control you are looking for, in this case a {textbox}. The easiest way to achieve this is to simply run the page and view the page source. It is there that you can find the name as it is rendered and sent to the browser, after that all you have to do us use document.getElementByID to get the object and setup your handler
Example:
<script>
//Place this AFTER your textbox control is declared in the HTML
//Get the textbox
var textbox = document.getElementById('nameOfRenderedControlHere');
//Assign the event handler and function you want it to call
textbox.onclick = function() { validateCaptcha(); };
function validateCaptcha()
{ //Do your Stuff here }
</script>
That should be it..havent tested, let me knwo if you run into questions.
Put the captcha in its own <asp:Panel> and add a DefaultButton property for the panel with the ID of the captcha's submit button.
