Set the Enabled Property of a UserControl From CodeBehind

It's been a while since I worked on WebForms so I need a refresher when working on an old site.

I have a userControl on the page that I need to programatically set the enabled state

<%@ Register Src="CalandarControl.ascx" TagName="CalandarControl" TagPrefix="uc" %>

I have this at the C# code but Enabled is not available here. What am I missing? 

if (c is UserControl)
{
    var x = c.GetType();
    if (x.Name == "calendarcontrol_ascx")
    {
        ((UserControl)c).Enabled = true;
    }
}

Thanks

you can define a panel in usercontrol witch cotaines all of controls of the user control, then define a property Enabled named as bool (panelMain.Enabled;) and from ur page set it,

in user control ascx

<asp:panel runat="server" id="panelMain" Enabled="false">

<!-- define ur other controls between panel-->

</asp:panel>

in usercontrol ascx.cs

public bool Enabled
{
    get { return panelMain.Enabled;  }
    set { panelMain.Enabled = value; }
}

in page first register ur usercontrol and then set Enabled property from code behind ....
for example

 protected void Page_load(object sender,EventArgs e )
 {
     panelMain.Enabled = true;
 }

as simple as drink water :))

You should have something on the code-front that places the control on the page, like:

<uc:CalendarControl ID="dtePrepaymentExpiresDate" FieldName="Prepayment expires date" runat="server" Enabled="false" />

Then in the code behind, you can set this custom property as follows:

dtePrepaymentExpiresDate.Enabled = true;

If you really need to do it in the loop, then you need to cast c as the CalendarControl and not UserControl because CalendarControl has the property Enabled while a normal UserControl does not.

((CalandarControl)c).Enabled = true;
