Using Generic Handler in ASP.NET

I am building a search bar in my web portal on asp.net.

I have created a Search1.aspx page in which I have an Image Label having image ID as "Image1". And on the Master Page I have a search button which generates the following event-

protected void Button1_Click(object sender, EventArgs e)

    {
        Image1.ImageUrl = "~/Handler1.ashx?imgid=" + TextBox1.Text;
    }

ERROR- The error which is showing is "Image1 does not exist in current context" in Site1.Master.cs file

You have Image1 in Search1 and and get an error that it is not in Site1 context. That is pretty self-explanatory. I'd advice you to start more basic from tutorials/books so you understand how asp.net works. – Allan S. Hansen

MasterPage has reference to Page object so you can access controls from page like that:

Image img = this.Page.FindControl("Image1") as Image;
img.ImageUrl = "~/Handler1.ashx?imgid=" + TextBox1.Text;
