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)

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

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"/>

Method 2

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

Method 3

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

Method 4

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.

Method 5

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.

Method 6

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>

Method 7

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 🙂

Method 8

Try to Clean your solution and then try once again.

It will definitely work. Because every thing in code seems to be ok.

Method 9

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.

Method 10

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

Method 11

in my case:
make sure not exist any form element in your page other than top main form,
this cause events not fired

Method 12

If the asp button is inside <a href="#" rel="nofollow noreferrer noopener"> </a> tag then also the Click event will not raise.

Hope it’s useful to some one.

Method 13

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
    }
 }

Method 14

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.

Method 15

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.
