Recently, I encountered a challenge with an ASP.NET page that contains both ASP.NET validators and JavaScript checks. As I delved into the button code behind the scenes:
protected void Button2_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
// ...
However, even when the validation fails, utilizing Page.IsValid resolves the issue. But there's a catch – it also resets all JavaScript variables in the process. Is there a way to circumvent entering the button code while still maintaining the integrity of the JavaScript variables? This situation becomes more intricate due to the presence of an Ajax Update Panel and image buttons on the page. Any suggestions or tips to navigate through this complexity would be greatly appreciated.
Below is a snippet of my ASPX file:
<%@ Page Language="C#" AutoEventWireup="true"
CodeBehind="WebForm2.aspx.cs"
Inherits="WebForm2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div style="width: 500px;">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<!-- Additional HTML content here -->
</div>
</form>
</body>
</html>
Furthermore, below are excerpts from my code-behind file for reference:
Although the provided information gives insights into what needs to be avoided—an enforced transition to button2_click despite failed validation—I'm in pursuit of finding a solution that can streamline the process without compromising any essential elements.
