Put a breakpoint and see what is happening. Just looking at it, it would appear that clicking No would return false and click Yes would return whatever DeleteNews returns. What does DeleteNews return?

its return an int id

OK. Then you'll need to put a breakpoint and walk through your code and see what is happening.

I suggest to create a new function and put logic in that function. This would improve maintanability

Try this

C#

onclick="return AskConfirmation();"

Function AskConfirmation()
{
    var answer = confirm('Are you sure you want to delete?');
        if (answer==true){
            DeleteNews(1);
        } else {
            return false;
        }
    return false;
}
