Is there anyway to rotate the polar chart so that it starts with 0 at the top of the graph instead of 0 being at the right?

ListControl with lazy loading

Hello!

I have a ListControl which can contain a lot of DescriptionTextListDataItem (even millions).

Every item could be customized with a different Icon or color.

Obviusly if I try to create all these items all together the process hangs forever.

What I'm trying to do is to show the first 100 elements and, when the user scroll to the end of the list, the next 100 elements are dinamically inserted into the list.

First question: is this reasonable or there's already a baked in way to do such a thing?

I've seen that there is a ScrollEventType.Last that could be useful to understand when the user scrolled down to the end, but... the "Scroll" event on the ListControl is never fired.

Is this an issue or am I missing something?

Thank you!

RadDateTimePicker Index was out range

I am working on the Bug Tracker sample and am getting this error when I try to run the program;

System.ArgumentOutOfRangeException: 'Index was out of range.

Must be a non-negative and less than size of the collection.

Parameter name index'

Below is the offending code. I am not seeing what is wrong with this;

private void ReadOnlyControls(bool readOnly)

{

titleTextBox.ReadOnly = readOnly;

idSpinEditor.ReadOnly = readOnly;

descriptionTextBox.ReadOnly = readOnly;

stepsToReproduceTextBox.ReadOnly = readOnly;

idSpinEditor.ShowUpDownButtons = !readOnly;

dateDateTimePicker.DateTimePickerElement.TextBoxElement.TextBoxItem.ReadOnly = readOnly;

RadDateTimePickerArrowButtonElement arrowButton = dateDateTimePicker.DateTimePickerElement.Children[1].Children[1] as RadDateTimePickerArrowButtonElement;

arrowButton.Visibility = readOnly ? ElementVisibility.Collapsed : ElementVisibility.Visible;

priorityDropDownList.DropDownListElement.ArrowButton.Visibility = readOnly ? ElementVisibility.Collapsed : ElementVisibility.Visible;

priorityDropDownList.DropDownListElement.TextBox.TextBoxItem.ReadOnly = readOnly;

statusDropDownList.DropDownListElement.ArrowButton.Visibility = readOnly ? ElementVisibility.Collapsed : ElementVisibility.Visible;

statusDropDownList.DropDownListElement.TextBox.TextBoxItem.ReadOnly = readOnly;

ownerDropDownList.DropDownListElement.ArrowButton.Visibility = readOnly ? ElementVisibility.Collapsed : ElementVisibility.Visible;

ownerDropDownList.DropDownListElement.TextBox.TextBoxItem.ReadOnly = readOnly;

}

InnerItem does not exist in the type 'RadQuickAccessToolBar'

I apologize if this is not the correct area, I did not see one for this.

With that said, I am working on the Bug Tracker example you have posted, and am trying to compile it and step thru what it does. I opened the ZIP file and extracted the contents. Went to compile the C# portion of the project and I get two errors.
The type name 'InnerItem' does not exist in the type of 'RadQuickAccessToolBar' and method 'GetInnerItem' accepting a first argument of type 'RadQuickAccessToolBar' could not be found (are you missing a directive or an assembly reference?)

This is the offending code section.

private void CustomizeRibbon()

{

radRibbonBar1.RibbonBarElement.ApplicationMenuRightColumnWidth = 0;

radRibbonBar1.OptionsButton.Visibility = ElementVisibility.Collapsed;

RibbonBar.ExitButton.Visibility = ElementVisibility.Collapsed;

RadQuickAccessToolBar.InnerItem item = RibbonBar.RibbonBarElement.QuickAccessToolBar.GetInnerItem();

item.Visibility = ElementVisibility.Collapsed;

radRibbonBar1.StartButtonImage = Resources.bug_logo;

}

I tried to update to the current WinControls.UI and that made it worse. Is this an older control thing?
