I seem to be having a problem with my button's OnClick, it doesn't even react at all to the event. It responds to OnClientClick and executes the code, but when I try to relate it o a function in my .aspx.cs class it just ignores it, and it should be executing very simple code (writing to the output debug)
I've checked every other stackoverflow post about this I could find and no one had the same issue.
I know that my Index.aspx is executing the code inside Index.aspx.cs because the Page_Load function is outputting to the debug window, so that's not the problem.
Here's the important code:
<asp:Button ID="btnCreateOrder" runat="server" Text="Create Order" OnClick="btnClick" />
protected void btnClick(object sender, EventArgs e)
{
System.Diagnostics.Debug.Write("Testing3");
}
Like I said the Page_Load function is working fine so it's not an issue of them not being connected.
DIFFERENT PROBLEM IF YOU FEEL SO INCLINED:
While you're reading, I also have a problem of not being able to find objects from my HTML in my CS file.
What I mean by that is, if I reference this label:
<asp:Label ID="testLabel" runat="server" Text="test"></asp:Label>
by saying
testLabel = "Test2";
I get the error "The name 'testLabel does not exist in the current context"
And if I try to reference it by saying this:
Index.testLabel = "Test2";
I get "'MyProject.Views.Home.Index' does not contain a definition for 'testLabel'" even though it clearly does.
Maybe the .designer file is bad.
Try this: delete the .designer.cs file of your .aspx page, right-click on it and select the 'Convert to web application' option.
EDIT: As for the Button event, how did you generate the method stub for the click event? Did you click the button on the designer view twice and the visual studio generated id for you or did you handcoded it?
Try to delete both the button and the button click event, and when you declare the button again, double click it on the designer view.

Coding a page in asp.net webforms, I put a button and textbox in site.master file.
I want to do a specific action (defined in a method) when I click in button, so I put this method in site.master.cs. This method, besides other things, take the value of textbox.
I can´t reach the method when I am clicking in it.
Am I coding it in a proper way?
Are there another way to do it?
This is the relevant code.
site.master
<input id="mailListaD" type="text" value="Introduce tu Email…" runat="server"
onfocus="this.value=(this.value=='Introduce tu Email…')? '' : this.value ;" />
<asp:Button id="news_go" Text="GO" OnClick="listaDistribucion_Click" runat="server"/>
site.master.cs
protected void listaDistribucion_Click(object sender, EventArgs e)
{
string query = "INSERT INTO listaDistribucion VALUES(''," + mailListaD.Value +")";
ExecuteQuery(query);
Close();
}
The error when I compile the proyect is:
error CS7036: There is no argument given that corresponds to the required formal parameter 'sender' of 'SiteMaster.listaDistribucion_Click(object, EventArgs)'
Try generating the event from the IntelliSense, delete the event that is attached to the button and then write OnClick=.. when intellisense appears click Create New Event and in the code behind you get an event that has the name of the id of the button and onclick appended to it.
Also check if you have the correct code behind page in your masterpage in the first line above CodeBehind="MyPage.aspx.cs", check if the name of your code behind is correct.
I am trying to put a Skip to Content link within my web application, but am having some issues.
Currently I have
<asp:LinkButton id="linkSkiptoContent" runat="server" OnClick="linkSKipToContent" Text="Skip to Content"></asp:LinkButton>
within the asp page
and an onClick event receiver
protected void linkSkipToContent_Click(object sender, EvenArgs e){
checkbox.Focus();
}
I am trying to avoid javascript because users have the option to disable it, which would render the link useless. And I know the checkbox.Focus() works properly, since I stuck it in the Page_Load() method and that worked at intented. However, what happens is clicking the link causes it to be focused after the onClick event completes.
Just print an anchor:
<a name="content" />
And link to it:
Go to content
Don't need JS or serverside stuff for that.
I have problem in asp.net button control.
I define a button in form, onclick event of button is not firing when I click on the button.
<asp:Button ID="btn_QuaSave" runat="server" Text="SAVE" OnClick="btn_QuaSave_Click" />
protected void btn_QuaSave_Click(object sender, EventArgs e)
{
}
Because your button is in control it could be that there is a validation from another control that don't allow the button to submit.
The result in my case was to add CausesValidation property to the button:
<asp:Button ID="btn_QuaSave" runat="server" Text="SAVE" OnClick="btn_QuaSave_Click" CausesValidation="False"/>
Have you copied this method from other page/application ? if yes then it will not work, So you need to delete the event and event name assigned to the button then go to design and go to button even properties go to onClick event double click next to it, it will generate event and it automatically assigns event name to the button.
this should work
I had the same problem, my aspnet button's click was not firing. It turns out that some where on other part of the page has an input with html "required" attribute on.
This might be sound strange, but once I remove the required attribute, the button just works normally.
If you are using updatepanel on onclick event, this may happen.
Use 'EnableEventValidation="false"' in your page markup like this :
<%# Page Language="C#" MasterPageFile="~/ars_home.master" AutoEventWireup="true" CodeFile="Transaction_Window.aspx.cs" Inherits="Transaction_Window" EnableEventValidation="false" %>
Hope this helps
I had a similar issue and none of the answers worked for me. Maybe someone finds my solution helpful. In case you do not mind submitting on button click, only attaching to click event setting UseSubmitBehavior="false" may be worth trying.
In my case I put required="required" inside CKEditor control.
Removing this attribute fixed the issue.
Before
<CKEditor:CKEditorControl ID="txtDescription" BasePath="/ckeditor/" runat="server" required="required"></CKEditor:CKEditorControl>
After
<CKEditor:CKEditorControl ID="txtDescription" BasePath="/ckeditor/" runat="server"></CKEditor:CKEditorControl>
i had the same problem did all changed the button and all above mentioned methods then I did a simple thing I was using two forms on a single page and form with in the form so I removed one and it worked :)
Try to Clean your solution and then try once again.
It will definitely work. Because every thing in code seems to be ok.

Try to go into Design mode in Visual Studio, locate the button and double click the button that should setup the event. Otherwise once the button is selected in Design more, go to the properties and try setting it from there.
Add validation groups for your validator elements. This allows you distinguish between different groups which to include in validation. Add validation group also to your submit button
in my case:
make sure not exist any form element in your page other than top main form,
this cause events not fired
If the asp button is inside tag then also the Click event will not raise.
Hope it's useful to some one.
In the case of nesting the LinkButton within a Repeater you must using something similar to the following:
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="MyUpdate">LinkButton</asp:LinkButton>
protected void Repeater1_OnItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName.Equals("MyUpdate"))
{
// some code
}
}
If it's throwing no error but still not firing the click event when you click the submit button, try to add action="YourPage.aspx" to your form.
Even i had two forms one for desktop view and other for mobile view , Removed one formed worked for me . I dint knew asp.page should have only one form.
Try this onserverclick
<button id ="DemoButton" runat="server" onserverclick="button_Click">Login</button>
I have default.aspx with a "Submit" Button and a code behind function called as "btn_Submit" which will perform submit action. Once I deploy the application and if there is any logical problem in btn_Submit code, then I can use runat=server script in default.aspx file and I need not go for another deployment.
But When I tried the same for ascx file, it works very well in development environment i.e in VS but when I move the same to Test server, system throws function not defined. I have renamed the existing function name.
So is it possible to add runat=server script and add c# code in ascx file?
Yes it is possible..
You have to surround your code with markup
<script language="c#" runat="server">
public void Page_Load(object sender, EventArgs e)
{
//hello, world!
}
</script>
Take a look to thisquestion! I think it will help you..
But it is really better to separate your code..
Did you tell the button which method to run on submit? With "auto event wireup" it will try to find a "buttonname_Click" method if you didn't specify anything. If that doesn't exist, you will get an error.
To call a method with a different name, specify that in the OnClick property of the button.
I am not sure why this happened and still was not able to solve it, So redeployed the application :(
Is there a way to click a link programatically, so that it has the same effects as if the user clicked on it?
Example:
I have an ASP.NET LinkButton:
<asp:LinkButton id="lnkExport" runat="server" CssClass="navclass">Export</asp:LinkButton>
I have a link on a sidebar directing to the .aspx page that has this linkbutton on it. For various reasons I can't have the code for the LinkButton executed until the page has refreshed -- so I am looking for a way to force-click this LinkButton in my code once the page is completely loaded. Is there a simple/doable way to accomplish this? If it involves triggering an event, please provide a code sample if you can. Thanks.
Triggering a click event programatically on a link will trigger the “onclick” event, but not the default action(href).
And since linkbuttons come out as hrefs, so you could try doing this with Javascript.
var lnkExport = document.getElementById('<%= lnkExport.ClientID %>');
if(lnkExport){
window.location = lnkExport.href;
}
I certainly think that, there is a design and implementation flaw which forces you to conclude as you described.
Well, invoking the click event means nothing but executing the event registration method.
So, the worst suggestion I can think of is, just call the function at what point you want to happen the click event like,
lnkExport_Click(lnkExport, new EventArgs());
Rashack's post show's how to do it. You can just do it in javascript.
function ClickLink() {
document.getElementById('').click();
}
If you want this to fire after some other event, you can add code in c# to add a call to that function on the client side when the page loads.
Page.ClientScript.RegisterStartupScript(
this.getType(),
"clickLink",
"ClickLink();",
true);
I'm not sure why you'd need your page to load if you're just wanting to programmatically click that link. I'd recommend using Response.Redirect() on the server side to redirect them to that page. Not sure if there are other extenuating reasons this simple approach won't work...

If i understand what you're saying:
<asp:LinkButton id="lnkExport" runat="server" CssClass="navclass" onclick="lnkExport_Click">Export</asp:LinkButton>
then in your codebehind or whenever call the following when you need to...
lnkExport_Click( null, null );
and make sure you've got lnkExport_Click wired up.
protected void lnkExport_Click( object sender, EventArgs e )
{
//DO Whatever here
}
<button onclick="document.getElementById('<%=this.lnkExport.ClienID%>').click()">
click me</button>
