How to to confirming before deleting in ASP.NET?

I have code like this in Page_Load()

btnMainDelete.Attributes.Add("onclick", "if(confirm('Are you sure you want to delete this?')){}else{return true}");

Basically, it's confirming that before deletion (Yes/No). If it's a yes then delete the record and if it's no then do nothing.

For the btnMainDelete, I put as follow:

<asp:Button ID="btnMainDelete" runat="server" Text="Delete" OnClick="btnMainDelete_Click" />

Now the issue is that, what I press Yes or No always executes btnMainDelete_Click on the server side? I must have something missing here.

Thanks

you want to modify your code with

<asp:Button ID="btnMainDelete" runat="server" Text="Delete" OnClientClick  ="javascript:confirm('Are you sure want to delete ?');" />

OnClientClick : Gets or sets the client-side script that executes when a Button control's Click event is raised.

OnClick : Raises the Click event of the Button control

So in your case the confirm it should raise a client-side script. So you should give in a OnClientClick event .

using this 

btnDelete.Attributes.Add("onclick", "return confirm('Do you really want to delete this item?'

This will delete forever item in your database!');");

Put valid confirm script in the OnClientClick:

<asp:Button ID="btnMainDelete" OnClientClick="javascript:return confirm('Are you sure?');" runat="server" Text="Delete" OnClick="btnMainDelete_Click" />

Put your script in the OnClientClick

e.g., 

btnMainDelete.OnClientClick = "if (confirm('Are you sure you want to delete this?') == false) return false;";

You need to fix your script. In the script as written it is never preventing further execution of the script by returning false.

try: 

return confirm('Are you sure you want to delete this?');

IE:

btnMainDelete.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this?');");
