Also I searched about it over google and here too but no use.

Here is my code

        if (CheckBox1.Checked == true)
            Label1.Text = "hello";
        else
            Label1.Text = "hi";
    }

Any help will be appreciated Please help me and Thanks in advance

Make Sure that the AutoPostBack property of the CheckBox is set to true. Also, this CheckBox might be inside an updatePanel and Label1 is not in an updatePanel.
