Hi Guys,
I have a situation....
I have to display one conformation(Yes/No) to user based on the server side logic. What I am planning was to write javascript in code behind itself.
But I have to call a serverside function if he clicks YES in conformation.

Do I have to implement ajax(WebMethods/Invoke attribute) to the server side function in order to make the server side function available to Javascript?
Or is there any other smart way to achive it.....

Thanks for your advice...

You can use ajax. you can call a .ashx or .aspx file.
Example:

var J = jQuery.noConflict();

function loadNextFiveStories() {
J.ajax({
url: "GetNextFiveStories.ashx",
type: "GET",
dataType: 'html',
data: { 'Next': id },
success: function (data) {

}
});
}

Solution 1

Not sure if this is what you are looking for.

<asp:LinkButton ID="lbAccept" runat="server" onclick="lbAccept_Click"
                                OnClientClick="return confirm('Are you sure you want to accept this ?')"
                                 ForeColor="Yellow" Font-Bold="True" style="font-size:18px">I Accept</asp:LinkButton>

This is just a simple link button that will show confirmation dialog box when user clicks on it and if user choose Yes then server side lbAccept_Click will be executed.

I could see your lblAccept_Click selling was wrong. It was cilck.
This is a minor edit and the editor should have checked 'Minor Edit' while editing.
