how to make switch case

Its no use of using Switch case,if you r having only one condition..

try this

bool bit = false; // bit value from sql will be converted to bool
                txtPassword.Visible = bit;

anyhow your switch case here.

switch (bit)
               {
                   case true:
                       txtPassword.Visible = true;
                       break;
                   case false:
                       txtPassword.Visible = true;
                       break;
                   default:
                       break;

               }

take one check box n make it enabled = false, autopostback=true,

add its event, click on checkbox go to events, double click Checked. it will generate event code at backend of the page.

in this event, add this code.

if(checkbox.checked)
{
 txtpwd.enabled = true;
}
else 
{
txtpwd.enabled = false;
}

plz let know if its works,

switch(condition)
{
 case 1:
  user define work;
  break;
 case 2:
  user define work;
  break;
 case 3:
  user define work;  
  break;
 case 4:
  user define work;
  break;
 default:
  user define work;
  break;
}

in condition should be output comes as 1,2,3,4....I am giving you example below

for(int i=1;i<6;i++)
{
switch(i)
{
 case 1:
  print "i is "+i;
  break;
 case 2:
  print "i is "+i;
  break;
 case 3:
  print "i is "+i;
  break;
 case 4:
  print "i is "+i;
  break;
 default:
  print "i is "+i;
  break;
}
}
