I have a simple form written in asp.net/C# and when trying to hit enter while in the form's input box doesn't submit the form for some reason. I had implemented a fix for a previous bug where pressing enter would merely refresh the page without submitting the form data but now pressing enter just does nothing, the fix is below:
<div style="display: none">
<input type="text" name="hiddenText" />
</div>
anybody know about a fix for this or a workaround?
I'm assuming you have a button somewhere on your page, as well as an event handler for it.
Have you tried wrapping your form (with the button) inside a Panel control and setting the default button attribute?
i.e.
<asp:Panel id="pnlMyForm" runat="server" DefaultButton="btnMyButton">
<asp:textbox id="txtInput" runat="server" />
<asp:Button id="btnMyButton" text="Submit" runat="server" />
</asp:Panel>
You can specify a default button for a form, which means hitting enter on any input control will fire that button (i.e. target the submit button). I haven't heard of this not working in any specific browser. This should eliminate your need for a workaround/hack.
<form id="form1" runat="server">
<asp:Panel ID="pnlFormContents" runat="server" DefaultButton="btnSubmit">
<!-- add some input controls as needed -->
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click"/>
</asp:Panel>
</form>
Hope this helps...
I don't remember the specifics of the rules, but most browsers have the capability of submitting forms when ENTER is pressed if conditions are met. I think it had to do with whether you had 1 or more-than-one field, or whether or not there was at least one submit button (even if you hide it). I've done it in a site I recently did, but I don't have the code handy, but I can tell you it works without any special scripting. Check this posting for more details:

I have the following command button:
<asp:Button Text="Insert Value" UseSubmitBehavior="false" runat="server" OnClientClick="return Confirmation.value('insert');" CommandName="Insert" />
I am using UseSubmitBehavior="false" to prevent ASP.Net page enter key causing post back
I do not want to listen to the enter keyCode via javascript because enter is used to submit non-webform elements not related to the form
Apparently, when using a Command and UseSubmitBehavior="false" then OnClientClick doesnt work. If I turn on submit behavior it works as expected but then hitting enter on the page automatically tries to click the button.
I prefer not to listen for the click event in Jquery or in javascript, and prefer a webform solution. Possible a better way of prevent enter from submitting the form or a way for OnClientClick to work properly with no submit behavior
You may need to use Panel and keep all your form inside Panel Tag and set the DefaultButton value of Panel to Button. Like Below:
<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
// other form elements
<asp:Button Text="Insert Value" ID="Button1" runat="server" OnClientClick="return Confirmation.value('insert');" />
</asp:Panel>
I have a set of options on an ASP.net page where the user may open up one of two lightboxes - either the "Add" lightbox or the "Edit" lightbox.
Each one has a small form for the user to fill out, and then they can hit a button at the bottom of the lightbox to hit submit.
I have the buttons set up within the lightboxes like so:
<asp:Button Id="btnSubmitAdd" runat="server" Text="Submit" OnClick="btnSubmitAdd_Click" />
... then later in the other lightbox...
<asp:Button Id="btnSubmitEdit" runat="server" Text="Submit" OnClick="btnSubmitEdit_Click" />
When i click the "Add" lightbox's submit button, everything behaves just fine.
When i click the "Edit" lightbox's submit button however, it fires "btnSubmitAdd_Click" instead of its own "...Edit_Click" event!
I have checked and re-checked all of the names and events and everything is set up correctly. Anyone have any ideas why this is happening?
Thanks to #MikeGuthrie for leading me down the correct path!
The issue seems to be with asp.net defaulting buttons to type "submit" which submits the entire form, and apparently that means it simply hit the first button's event before the second.
I added have modified the buttons like so and things are working now:
<asp:Button Id="btnSubmitAdd" runat="server" Text="Submit" OnClick="btnSubmitAdd_Click" UseSubmitBehavior="false"/>
<asp:Button Id="btnSubmitEdit" runat="server" Text="Submit" OnClick="btnSubmitEdit_Click" UseSubmitBehavior="false"/>
I have put server side validations for each text box using <asp:RequiredFieldValidator/>. I have called ClearFields() method on page load that will clear all fields on the form when the button is clicked. The problem is that when the form gets posted and the fields are cleared, the validation message appears again. How to hide the validation messages on form post back. I am sorry, but its been years I have not coded in aspx and I can't find any solution online.
This is the textbox code:
<asp:TextBox runat="server" CssClass="form-control" placeholder="Your Name *" ID="name"/>
<asp:RequiredFieldValidator runat="server" ControlToValidate="name" ErrorMessage="Name seems empty" CssClass="help-block text-danger"></asp:RequiredFieldValidator>
This is the button code:
<asp:Button runat="server" class="btn btn-xl" Text="Send Message" ID="submit" OnClick="submit_Click" CausesValidation="false"/>
I guess you are getting the validation message due to button used for clearing the fields. Set CausesValidation property of button to false:-
<asp:Button ID="ClearButton" runat="server" CausesValidation="false" Text="Clear" />
Also, please note asp:RequiredFieldValidator works on client side i.e on the browser it is not a server side validation.
Update:
Since you are clearing your fields on click of button, you can clear in submit_Click method itself after sending the email instead of page load. Ideally you should have a separate button to clear the form though.
I have a simple proof of concept web page. It uses one master page and one content page, the default one, default.aspx. I'm doing some client side debugging with alert boxes. I dragged an asp.net button onto the page and set CausesValidation = false and UseSubmitBehavior = false and yet when I click it the page submits.
What am I doing wrong?
Here is a design time code....
<asp:Button ID="Button1" runat="server" Text="Button" UseSubmitBehavior="False" CausesValidation="False" />
Here is Runtime render, wth is it putting in a PostBack?
<input type="button" name="ctl00$ContentPlaceHolder1$Button1" value="Button" onclick="javascript:__doPostBack('ctl00$ContentPlaceHolder1$Button1','')" id="ContentPlaceHolder1_Button1" />
--Update--
Thanks Volkan Paksoy, that worked. For those who suggested HTML buttons, that worked too and that is what I used, but I was just curious why the ASP.NET button wouldn't work. It's something I should know and probably something I knew and forgot. Thanks for the help
If you need to use asp:Button and disable submit you can add OnclientClick function such as:
<asp:Button ID="Button1" runat="server"
CausesValidation="False"
OnClick="Button1_Click"
Text="Button"
UseSubmitBehavior="False"
OnClientClick="return false;" />
This should stop the postback. But you can simply use an input too of course. This is just one way of doing it.
If you want to create a button that does not submit the page/postback to the server, you could create one using raw HTML like so:
<input type="button" />
I am using Page.Isvalid function in my web page.I have two buttons in my web page namely "save" and "generate".when i click the save button the validation summary will be invoked in which all the validations in this page will be shown.
Now I dont want to show a particular validation message for the "Save" button, but the same validation message should be shown specifically to "generate" button in the same page.
But i am using Page.Isvalid in the "save" button click which is displaying all the validation messages in the page.
Any help would be deeply appreciated.Thanks
You can use ValidationGroup(s) to do this.
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="R1" runat="server"
ErrorMessage="*"
ValidationGroup="GenerateOnly"
ControlToValidate="TextBox1" />
<asp:Button ID="Generate" runat="server" Text="Generate"
ValidationGroup="GenerateOnly" />
<asp:Button ID="Save" runat="server" Text="Save" />
</div>
</form>
This example triggers the validator if Generate is clicked, but not when Save is clicked, and also works when calling Page.IsValid in the buttons onclick function.
not entirely sure what you mean but here goes.
If you want both the save and generate buttons to generate validation messages then why not move the Page.Isvalid along with the validation code into another method. Call this method from both the save and generate methods.
If I've got the wrong end of the stick please let me know a bit more.
Cheers Tigger
Ya buddy if you have to call the same function for two different buttons it is not possible without the concept of overloading. Otherwise you have to create two methods.
But I'am not sure as i am a begginer
