Cant access asp labels properties using c# in aspx page

I am trying to access an asp label field properties from c# code, and it keeps giving me the error:
The name 'lblTest' does not exist in the current context.
This is happening on my login.aspx page when calling the 'ValidateEmail' method.
There are no associated .cs files, just a login.master page.
I have a business request requiring me to modify someone elses code for enhancement, and I am guessing this has something to do with the existing content structure of .
I have tried placing this in master file, outside of the structure, etc. Still no joy.
Here is the login.aspx code:

Verifying that a multidimensional array contains a pair of values

I am making a signin form for a webpage. I have created a multidimensional array with acceptable username/password combinations. I would like to allow the user to move on to the next page only if their username/password combination is found in the array. If they enter a combination that is not found in the array, I want an error to raise and keep them from proceeding to the next page.
I understand that this is not the most effective way to complete this command, but I am learning how to properly use Arrays as part of the foundation to my programming knowledge. I'll paste my code below. I've tried various way to get the page to do what I want, but I can't seem to get it. I get this error: "System.IndexOutOfRangeException: Index was outside the bounds of the array." Here is my code:
<%# Page Language="C#" %>
<!DOCTYPE html>
<script runat="server">
string[,] UserPass = new string[,] {{"user1","pwd1"}, {"user2", "pwd2"}, {"user3","pwd3"}};
void Page_Load(object sender, EventArgs e)
{
}
void btnSignin_Click(object sender, EventArgs e)
{
if(txtSignin.Text == UserPass[1,0] && txtPWD.Text == UserPass[0,1])
{
Response.Redirect("welcome.aspx");
}
else if (txtSignin.Text == UserPass[2, 0] && txtPWD.Text == UserPass[0, 2])
{
Response.Redirect("welcome.aspx");
}
else if (txtSignin.Text == UserPass[3, 0] && txtPWD.Text == UserPass[0, 3])
{
Response.Redirect("welcome.aspx");
}
else
{
Response.Write("Please try again.");
}
}

</asp:Panel>
<asp:Label ID="lblSignin" runat="server" />
</div>
</form>
</body>
</html>
(also, on a smaller note, is it possible to have the signin/password boxes display text that disappears when the users clicks the textbox?)
Thank you for any help!

There are different options. One is using arrays with a for loop and another is using Linq. I will show you how to do it with arrays.
string[,] UserPass = new string[,] {{"user1","pwd1"}, {"user2.edu", "pwd2"}, {"user3","pwd3"}};
...
bool isFound = false;
for (int i=0; i< UserPass.GetLength(0); i++)
{
//search users row by row
if (UserPass[i, 0] == yourSearchUserid && UserPass[i, 1] == yourSearchPassword)
{
isFound = true;
break;
}
}
//isFound holds the search result.

How to get return value (value type is Ext.Net.Panel) from DirectMethod in javascript and add it to a Ext.Net.TabPanel?

Ext.net v2.2
.Net Framework v4.5
My Direct Method
[DirectMethod]
public static Panel AddTab(int postId)
{
var pnlEditPost = new Panel
{
ID = postId.ToString(),
Icon = Icon.BookEdit,
Title = "Edit",
Layout = "Fit",
Closable = true,
AutoDoLayout = true
};
return pnlEditPost;
}
I need get the pnlEditPost in javascript and add it to my TabPanel

The exact answer is no way to return a Panel instance.
But you can return a string with a Panel's config.
<%# Page Language="C#" %>
<%# Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
[DirectMethod]
public static string AddTab(int count)
{
return ComponentLoader.ToConfig(new Ext.Net.Panel
{
Title = "Tab " + count,
Html = "Server time: " + DateTime.Now.ToLongTimeString()
});
}
</script>
<!DOCTYPE html>
<html>
<head runat="server">
<title>Ext.NET v2 Example</title>
<script>
var addTab = function () {
var tabPanel = App.TabPanel1;
App.direct.AddTab(tabPanel.items.getCount(), {
success: function (result) {
var tabs = tabPanel.add(eval(result));
tabPanel.setActiveTab(tabs[0]);
}
});
};
</script>
</head>
<body>
<form runat="server">
<ext:ResourceManager runat="server" />
<ext:Button runat="server" Text="Add tab" Handler="addTab" />
<ext:TabPanel ID="TabPanel1" runat="server" />
</form>
</body>
</html>

Show another image onmouseover in javascript

I am having a problem with my javascript in Visual Studio. What I want to do is when i hover over the region of the country, like on this site www.pazar3.mk, a new image from that region should appear (which is transparent) with new color. I am going to post the code that I have. It doesn't return errors, but it doesn't work either. It just takes me to another .aspx site when I click on the region and it doesn't show the other image with the new color. Here's the code that I have, so please, can you tell me what I'm missing or should I change something with my code?
