Hi,
Thanks for posting here. I am not sure how you are storing Roles in your Windows Application. But you can apply a conditional logic to display or change the functionality of Button.


if(userRole == "Admin")
     btnDelete.Visible = true;
else
     btnDelete.Visible = false;

If you are still unable to apply your logic, please share your code, we will help you getting your desired result.

Hi,

You can do this by client side script using jquery as well.
Please find below code snippet for the same.

var role=$( "#ddlRole option:selected" ).text().trim();
if(role=="Admin")
$("#btnDelete").attr("disabled", true);
else
$("#btnDelete") .removeAttr("disabled");

so basically depend upon the rights you need to disable or enable Button. it is simple and basic


if(UserRight != "Admin")
     btnDel.Disabled =  true;
else
     btnDel.Disabled =  false;

Hi,
1. When u r on login form, pass selected rights i.e. (user/admin) to 2nd form where you enter product stock.
Refer this link for techniques to pass data within windows forms:
http://net-informations.com/q/faq/passvalues.html
2. After this get that passed value on 2nd form and code accordingly [Use code posted above by our DNS members].

Hi
Get the value use the code



DataTable Dt = new DataTable();
            SqlDataAdapter sqlcmd = new SqlDataAdapter("select username,password,AdminRights where users='" & TxtUSerName.Text & "' and Password='" & TxtUSerName.Text & "'", con);
            sqlcmd.Fill(Dt);
            Session["AdminRights"] = Dt.DefaultView[0]["AdminRights"].ToString();

Checking Rights



 //checking Rights
            if (Session["AdminRights"] == "Yes")
            {
                //Allow Enable
            }
            else
            {
                //Disable use
            }

Hi,

If you want to enable disable button based on user permission level then refer below sample code.


if(UserRole=="Admin)
               btnEdit.Enable=true;
else if(UserRole=="User")
               btnEdit.Enable=false;
