asp.net Button OnClick event not firing

Question

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)
{

}

Does this help? stackoverflow.com/questions/2669448/onclick-not-firing — keyboardP

check the CausesValidation property of your button. set it to False if its true. Also check your asp.net page code file link is exactly same in which you have put the event. — Jibran Khan

Is the button inside a template control (such as an <asp:Repeater> or <asp:GridView>)? — freefaller

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 not copy it from other page

I ended up reading your answer and deciding to move the page, create a new one named the same and manually move the markup and code behind. Worked like a charm!

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.

so weird. This error made me compose my code all over again. Still the same. Thank you for this tip. Had to commend you sir.

if you can ignore required fields put CausesValidation="false" in your asp:button

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.

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

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>

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.

Try to Clean your solution and then try once again.

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

If the asp button is inside <a href="#"> </a> 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.
