title: How to implement IF statement using GridView
body: <p>I am working on my first web project and I need help adding IF logic when using GridView. I have a page (CustomerListPage) that has a GridView item that displays a list of customers(rows) that can be clicked. Once the customer is clicked, the user is redirected to a page called "CustomerUsagePage" which shows the most recent record of this customer. This is what my GridView code looks like for my CustomerListPage:</p>
  
  <pre><code> if (GridView1.SelectedRow.RowIndex == 0)
     {
         //string selectedUser = GridView1.SelectedRow.Cells[0].ToString();
         Response.Redirect("CustomerUsagePage.aspx?Customer_Name=" );
         BindGridview();
     }
  </code></pre>
  
  <p>The code for my CustomerUsagePage looks like this: </p>
  
  <pre><code>private void BindControlvalues()
  {
  
      con.Open();
      SqlCommand cmd = new SqlCommand("select * from dbo.CustomerTable", con);
      SqlDataAdapter da = new SqlDataAdapter(cmd);
      con.Close();
      DataSet ds = new DataSet();
      da.Fill(ds);
      Label4.Text = ds.Tables[0].Rows[0][1].ToString();
      Label1.Text = ds.Tables[0].Rows[0][0].ToString();
      Label2.Text = ds.Tables[0].Rows[0][3].ToString();
      Label3.Text = ds.Tables[0].Rows[0][4].ToString();
  }
  </code></pre>
  
  <p>My problem is that I can only add IF logic the page where my GridView is located. I would like to click on a customer and have his data appear on my CustomerUsagePage with an if statement. Is it possible? I know I can do this by adding a page per customer but I dont want to go down that route, it seems to tedious. Does anyone have any suggestions? </p>
