How to enable / disable ALL controls (textboxes, dropdowns, checkboxes) on a page (on page load) based on some values in database?


I want to disable (make it read only)
all user input controls (like textboxes, dropdowns, checkboxes, radiobuttons)
on a page (on page load) based on some value in the database.

How do I achieve this?

I usually do this by creating some sort of method called "ResetFields()" and then call it in the Page_Load function.

Make sure to check if the page is posted back first:

If (!IsPostBack) {

As far as getting the value from the database, you can do something like the attached code snippet.

I wrote this from the top of my head just in the text I had no error checking...
using System.Data.SqlClient;
String connStr = ConfigurationManager.ConnectionStrings("ConnectionStringName").ToString();
SQLConnection sqlcon = New SQLConnection;
SQLCommand SQLcom = new SQLCommand;
sqlcon.ConnectionString = connStr;
sqlcom.CommandText = "SELECT Whatever FROM Table";
sqlcom.Connection = sqlcon;
String result = sqlcom.ExecuteScalar();

Thanks for the quick reply.

Can you please tell me which line actually does the disabling part?

YourControlName.Enabled = False;

Sorry. I didn't put it. That goes in ResetFields() routine.

I'm on my iPhone right now. Sorry for the brief response.

The way you suggested, we will have write command for each and every control..I want a way by which ALL controls are disabled in one shot...

here you go. I put most of the controls, but add controls as you like (as long as they have the "Enabled" property).

//Run method:
//Code for method
    private void DisableAllControls(Control Page)
        foreach (Control ctrl in Page.Controls)
            if (ctrl is TextBox) ((TextBox) (ctrl)).Enabled = false;
            else if (ctrl is Button) ((Button)(ctrl)).Enabled = false;
            else if (ctrl is DropDownList) ((DropDownList)(ctrl)).Enabled = false;
            else if (ctrl is ListBox) ((ListBox)(ctrl)).Enabled = false;
            else if (ctrl is CheckBox) ((CheckBox)(ctrl)).Enabled = false;
            else if (ctrl is CheckBoxList) ((CheckBoxList)(ctrl)).Enabled = false;
            else if (ctrl is RadioButton) ((RadioButton)(ctrl)).Enabled = false;
            else if (ctrl is RadioButtonList) ((RadioButtonList)(ctrl)).Enabled = false;
                if (ctrl.Controls.Count > 0) DisableAllControls(ctrl);
