This code is invalid, it won't even compile. If an "else" isn't working then there is a problem with your code as your code can't be what is posted above. To give you help we'll need to see the actual code, but Solution 1 is what you need, I suspect you are maybe placing your else in the wrong place.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class salaried : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)

That code won't compile. You need something like

if (TextBox1.Text != "india" || TextBox3.Text != "50000")
{
Response.Write("alert('Not eligible')");
}
else
{
Response.Redirect("saldetail.aspx");
}

dear sir

i want to add another validation on another text box. the validation is " the age entered by the user should be between 20 and 60". how to cater this ? i am trying below code but it is not working

if (age > 22 && age < 60)

You should look at the built-in validation controls, such as asp:RequiredField, or to solve your age issue asp:RangeValidator

Solution 1

You can use following

protected void Button1_Click(object sender, EventArgs e)
{
if (TextBox1.Text != "india")
{
  if (TextBox3.Text != "50000")
  {
   Response.Write("alert('Not eligible')");
  }
}
else {
   Response.Redirect("http://www.microsoft.com");
}
