Display a alert box in ASP.net c# web application

Question

I want to display a alert message when a user clicks on button.

I have a button "Signed" on click of this button I want to display a alert message saying "Are you sure you want to continue?" and two buttons in this alert message box "Yes" and "No".

On click of yes button I want a update function to be executed and on click of "No" only Alert should get closed and no changes in the current page.

Please anyone can guide me how to go on with this?

I have absolutely no idea about javascript or jquery. Can you help me out with any tutorials online for beginners? how do i use it with ASP.net? thank you @Nighil — Ishan

You can use the OnClientClick on the button for this. Add a return confirm(); to it. It will create a javascript confirm dialog, BEFORE it fires the click event. If the user presses no, it will not trigger the OnClick event.

OnClientClick="return confirm('Are you sure you want to continue?');"

So, added to your button markup, it would look like this:

<asp:Button ID="Button5" runat="server" Text="Signed" Visible="False" onclick="Button5_Click" OnClientClick="return confirm('Are you sure you want to continue?');" />

<asp:Button ID="Button5" runat="server" Text="Signed" Visible="False" onclick="Button5_Click" /> this is my button code. where do i add the above code you mentioned?in a class file for buttonclick event?

Just add the code i printed, inside your button tag. It will fire before your Button5_Click, and Button5_Click will then only fire, if the users presses yes.

jquery should do for you.

$("#ButtonId").click({
    return confirm("Are you sure you want to continue");
})
