Hey swapnil jatkar....
you can do this by simply calling some functions (e.g. LoginAdmin(), LoginAccnt() etc.), in which you can place a code to Enable or Disable the Menu Items........
For expected Result that you want, you need to call these functions at time of LOGIN with proper 'UserName' that you want...
Example:
Login Page:-
User Name: Admin
Password : Admin
Click 'Login' Button
@ 'OnClick' event of 'Login' Button:-
if(username=="Admin")
{ LoginAdmin(); }
else if(username=="Accountant")
{ LoginAccnt(); }
Functions:
LoginAdmin()
{
mnuBudget.Enable=true;
mnuPayment.Enable=true;
}
LoginAccnt()
{
mnuBudget.Enable=false;
mnuPayment.Enable=false;
}
