SelectedDatePicker tooltip value

[Lukrs]

Hi,

I have encountered a problem, with SelectedDatePicker a child control of RadScheduler. The event I pasted below changes the default tooltip of SelectedDatePicker. Somehow AJAX requests change the tooltip value back to default. If I do a page refresh, the value is set as it should be again.

I would really appreciate your help,
thanks in advance, LP, Luka


 protected void RadScheduler1_Load(object sender, EventArgs e)
    {
        RadDatePicker dateP = this.RadScheduler1.FindControl("SelectedDatePicker") as RadDatePicker;
        dateP.ToolTip = "Izberite datum";
    }

Hello Luka,

You need to set the ToolTip to the DatePopupButton of RadDatePicker. Also, you should use PreRenderComplete event, since RadScheduler's event happens too early.

 protected void Page_PreRenderComplete(object sender, EventArgs e)
    {
        RadDatePicker dateP = this.RadScheduler1.FindControl("SelectedDatePicker") as RadDatePicker;
        dateP.DatePopupButton.ToolTip = "Izberite datum";
    }

Hi,

I tried that, but when I try to open the advanced edit form an error occurs in the
Page_PreRenderComplete.

It says:


Object reference not set to an instance of an object.

and the advanced edit or insert form isn't opened because of that error.

Hello Luka,

This is strange - we did not experience such an error on our side. Can you send us a demo project via a support ticket?

Kind regards,

Hi,

It is strange, that you didn't experience souch a problem on your side.

I have worked on the problem, and found out the reason for the exception is probably that the SelectedDatePicker is never needed or shown in advanced edit/insert form. Therefore the object is never created.

That is no longer a problem....I used a try-catch block to solve this.

But the advanced edit/insert form has three more date pickers (StartDate, EndDate and the datepicker for the end of range).

How do I reference these datepickers? The Table of Contents only shows how to access SelectedDatePicker.

Hello Luka,

Please, try the following code:

protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
    {
        if ((RadScheduler1.SelectedView == SchedulerViewType.MonthView) & (e.Container.Mode == SchedulerFormMode.AdvancedInsert))
        {
            RadDateInput endTimeTimeInput = (RadDateInput)e.Container.FindControl("EndTime");
            RadDatePicker endTimeDatePicker = (RadDatePicker)e.Container.FindControl("EndDate");
            RadDateInput startTimeTimeInput = (RadDateInput)e.Container.FindControl("StartTime");
            RadDatePicker startTimeDatePicker = (RadDatePicker)e.Container.FindControl("StartDate");
         }
}

In general, you can use the kb article on How to access controls in the advanced form.

Hello Peter,

I used the following event:

    protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
    {
        string CalPopupText = "Izberite datum";

        if (e.Container.Mode == SchedulerFormMode.AdvancedInsert || e.Container.Mode == SchedulerFormMode.AdvancedEdit)
        {
           
            RadDatePicker endTimeDatePicker = (RadDatePicker)e.Container.FindControl("EndDate");
            RadDatePicker startTimeDatePicker = (RadDatePicker)e.Container.FindControl("StartDate");
            RadDatePicker RangeEndDatePicker = (RadDatePicker)e.Container.FindControl("RangeEndDate");

            endTimeDatePicker.DatePopupButton.ToolTip = CalPopupText;
            startTimeDatePicker.DatePopupButton.ToolTip = CalPopupText;
            RangeEndDatePicker.DatePopupButton.ToolTip = CalPopupText;
        }
    }


Works like a charm :)

Thank you,
LP, Luka
