Make a form as a readonly on runtime

Hello Sanjay,

i think following might help:

execute a loop for each control in the form and set read only property to   true here i am providing example of textbox only, you can add as many "if else" conditions as you like depending on the condition:

foreach (Control ctrl in this.Controls)
            {
                if (ctrl is TextBox)
                {
                    ((TextBox)ctrl).ReadOnly = true;
                }
            }

thanks and regards
