Questions:
After countless tries, my login isn’t working. I can’t figure out for the life of me why. Not sure if the problem is in my C# code, or my HTML code. On my popout form, you input your credentials and it redirects you to the default page. It’s not doing either and I’m hoping someone could help me out!
Here is my HTML-
<form class="form-container">
<h1>Login</h1>
<p style="text-align:center">Please login using your <strong><em>User ID and Password</em></strong></p>
<label for="Login"><b>User ID</b></label>
<input type="text" placeholder="Enter User ID" name="Login" required="" id="username" />
<label for="password"><b>Password</b></label>
<input type="password" placeholder="Enter Password" name="password" required="" id="Password" />
<button type="submit" class="btn" onclick="CheckUserLogon">Login</button>
<button type="button" class="btn cancel" onclick="closeForm()">Close</button>
</form>
<script>
function CheckUserLogon() {
var objButton = document.getElementById("CheckUserLogon");
objButton.click();
Response.Redirect("~/WebForm1.aspx");
}
function openForm() {
document.getElementById("myForm").style.display = "block";
}
function closeForm() {
document.getElementById("myForm").style.display = "none";
}
</script>

When I click the login, I then am suppose to be logged in, and the WebForm1 is suppose to open up, instead nothing is happening. I added a method="get" in my Form and it still does the same thing. Not really sure where to go as I’ve added all I could in terms of script and Button click. Might be something wrong with my C# Method of CheckUserLogon. At this point, anything would be helpful.
