[Solved] How to disable StartDate and EndDate controls

[Michael Malone]

I need to prevent the user from changing the start and end date in the AdvancedForm. I managed to get a reference to the controls in FormCreated() and set their Enabled property to False. This works as expected, but if I click inside the disabled control it throws a javascript error of "Microsoft JScript runtime error: 'undefined' is null or not an object".  How can I disable these controls without causing an error? 

void RadScheduler1_FormCreated(object sender, Telerik.Web.UI.SchedulerFormCreatedEventArgs e)
{
        if (e.Container.Mode == SchedulerFormMode.AdvancedInsert
            || e.Container.Mode == SchedulerFormMode.AdvancedEdit)
        {


            RadDatePicker startDate = (RadDatePicker)e.Container.FindControl("StartDate");
            startDate.Enabled = false;

        }

}

Hi Michael,

In the ticket info I see you are using version 2010.2 826. Is that true?

I tried to reproduce the issue with this version and no javascript error appears.

Correct, that is the version I am using. Setting Enabled=false still causes the javascript error. Setting "ReadOnly=true" does not cause an error.

Hi Michael Malone,

Have you customized the Advanced Form? I can not reproduce the issue.
Could you please send me your code so I can inspect it and help you?
