RadScheduler ReadOnly ContextMenu for certain users

[Rubihno]

Hi,

In my radschuder i have implement the example code that i find in this page:

http://demos.telerik.com/ASPNET/Prometheus/Scheduler/Examples/ContextMenu/DefaultCS.aspx

If not use this contextmenu is simple to set the readonly if the users is not administrator..

But how i make to set the readonly on scheduler with the contextmenu?, because use javascript...

example

if row("UserAdmin") = "1" Then

radscheduler1.readonly = true

Else

radscheduler1.readonly = true

End if

How i make if i use the contextmenu click for insert o modifify appointment?
Show or hide the contextmenu...

[Rubihno]

How can i do?

Hello Rubihno,

First, you need to add the menu item which will disable RadScheduler:

<telerik:RadMenuItem Text="Appointment menu" Enabled="false" />
                <telerik:RadMenuItem Text="Delete" Value="Delete" />
                <telerik:RadMenuItem Text="Edit" Value="Edit" />
                <telerik:RadMenuItem Text="Disable scheduler" Value="Disable" />

Then attach to the ItemClick server event of RadMenu (double click the control in design time) and set the ReadOnly property of RadScheduler:

 protected void SchedulerAppointmentContextMenu_ItemClick(object sender, RadMenuEventArgs e)
        {
            if(e.Item.Value == "Disable")
                RadScheduler1.ReadOnly = true;
        }

Let us know if you have further questions.

Yes this solution is correctly, but the problem is another, i would you like for example:

if  user is administrator show the radcontextmenu for insert or modify, but is not user administrator don't show the radcontextmenu, in practice hide SchedulerTimeSlotContextMenu and SchedulerAppointmentContextMenu.


Example code that i use:

You can use a hidden field to store the current user. Then you can access the hidden field and check the current user on the client. For example:

aspx:

 <asp:HiddenField ID="CurrentUser" runat="server" />
    <script type="text/javascript">
        function checkCurrentUser()
        {
            var currentUser = document.getElementById("CurrentUser").value;
            if(currentUser == "Admin")
            {
                alert(currentUser);
                //use the code from the online example to show the menu
            }

        }
        window.onload = checkCurrentUser;

    </script>

code-behind:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string user = "Admin";
            if (user == "Admin")
                CurrentUser.Value = "Admin";
        }
    }

This is just an example how to access a value which you have stored on the server at the client side. You will have to adapt this approach as per your need.
