Hi,

I try to make restriction for different type of user. As for superadmin can access all dropdownlist, for trainer only can access certain dropdownlist and for user too. But unfortunately my code return syntax error. Please help me to solve this problem.

What I have tried:

ASP Code:
<asp:DropDownList ID="deptDropDownList" runat="server" AppendDataBoundItems="True" AutoPostBack="True"
DataValueField="deptName" Height="22px" Width="132px">
<asp:ListItem Value="">-- Select Option --
<asp:ListItem Value="Training">Training Module
<asp:ListItem Value="MFG Module">MFG Module
<asp:ListItem Value="SelfLearning">Employee Training Record
<asp:ListItem Value="Others">Others
<asp:ListItem Value="InterviewTrackingSystem">Interview Tracking System
<asp:ListItem Value="ListOfEmployee">List Of Employee

Behind Code :

If (reader("emp_type").ToString() = "superadmin" And reader("trainer_AccessModule").ToString()) Then
(deptDropDownList.SelectedValue = "Training".Visible) = "True"
(deptDropDownList.SelectedValue = "MFG Module".Visible) = "True"
(deptDropDownList.SelectedValue = "SelfLearning".Visible) = "True"
(deptDropDownList.SelectedValue = "Others".Visible) = "True"
(deptDropDownList.SelectedValue = "InterviewTrackingSystem".Visible) = "True"
(deptDropDownList.SelectedValue = "ListOfEmployee".Visible) = "True"

And so on

(deptDropDownList.SelectedValue = "Training".Visible) = "True"

This makes no sense, what is it you're trying to do? "Training" is a string, it doesn't have a "Visible" property, and if you did set SelectedValue to something the result of that wouldn't be "True" either as that is another string.

F-ES Sitecore thank you for your answer. Can you suggest me how to fix it? Is there any way?

You'll have to explain what it is you're trying to do.

I try to make restriction for every dropdownlist. For example dropdownlist for value = "Training", all user can access. But for dropdownlist value = "List Of Employee" only superadmin can access. It will grey out for Trainer & User.

I'm not exactly sure what you are trying to achieve. Your description is still confusing. However, if you want to only see specific items in your DropDownList based on some user roles, then you can do something like this:

First, you have to clear out the static items from your DropDown in your HTML markup (.aspx) like:

ASP.NET

<asp:DropDownList ID="deptDropDownList" runat="server" AppendDataBoundItems="False" AutoPostBack="True" />

C#

var role = reader["emp_type"].ToString().ToLower();

deptDropDownList.Items.Clear();
if(role.Equals("superadmin")){
      	deptDropDownList.Items.Add(new ListItem("Training", "Training"));
	deptDropDownList.Items.Add(new ListItem("MFGModule", "MFG Module"));
	deptDropDownList.Items.Add(new ListItem("SelfLearning", "Self Learning"));
	deptDropDownList.Items.Add(new ListItem("InterviewTrackingSystem", "Interview Tracking System"));
	deptDropDownList.Items.Add(new ListItem("Others", "Others"));
	deptDropDownList.Items.Add(new ListItem("ListOfEmployee", "List Of Employee"));
}
else if (role.Equals("trainer")){
	deptDropDownList.Items.Add(new ListItem("Training", "Training"));
}
else if (role.Equals("whatever")){
     //add appropriate items to your DropDownList
}

VB

Dim role As var = reader("emp_type").ToString.ToLower
deptDropDownList.Items.Clear
If role.Equals("superadmin") Then
    deptDropDownList.Items.Add(New ListItem("Training", "Training"))
    deptDropDownList.Items.Add(New ListItem("MFGModule", "MFG Module"))
    deptDropDownList.Items.Add(New ListItem("SelfLearning", "Self Learning"))
    deptDropDownList.Items.Add(New ListItem("InterviewTrackingSystem", "Interview Tracking System"))
    deptDropDownList.Items.Add(New ListItem("Others", "Others"))
    deptDropDownList.Items.Add(New ListItem("ListOfEmployee", "List Of Employee"))
ElseIf role.Equals("trainer") Then
    deptDropDownList.Items.Add(New ListItem("Training", "Training"))
ElseIf role.Equals("whatever") Then
    'add appropriate items to your DropDownList
End If
