    This is probably a simple answer, and I'm just not seeing it.
    I'm using the Custom Advanced Form example, and what I would like to do is hide the Resource drop down list located within the user controls based on a value on my Scheduler page. For example, if lblOwner.text="N" on the scheduler page, then hide the resource drop down on the advanced form when editing or creating an appointment.

    How would I go about accessing those controls?

    Hello Nick,

    I suggest you use OnFormCreated event to determine which controls to show. You can use e.Container.FindControl method to find the control.

    I've found that e.Container.FindControl doesn't work for finding AdvancedForm controls when using the custom AdvancedForm. Like for instance, if my resource is named ResRoom, the RadComboBox ID is generated ResRoom_ResourceValue.

    e.Container.ClientID doesn't build out the actual ID that would reference FindControl either. Any suggestions?

    Hello Nick,

    This is behavior is expected. You may inspect with the debugger,  set a watch for e.Container and check what exactly is returned and kept within this variable. You may find below a code, that demonstrates hiding the reminders drop-down field from the advanced form. You can use our demo here and apply this code to see how that works.

    protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
        RadComboBox reminder = (RadComboBox)e.Container.Controls[1].FindControl("ReminderDropDown");
        reminder.Visible = false;

    Hope this will be helpful.

    Kind regards,
