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?

Tab control

Hello,

I'm looking for a tab control like the attached one.

Is there a winforms control which can be customized to look like that?

I've tried with Dock, but i don't want the user to drag around or close the tabs, and the Dock does not allow to arrange the tabs on the left without vertically rotating the text.

Thank you!

Change DropDownList item color

I have my object and all it's properties that i want to populate inside my DropDownList and i am doing this in this way:

DescriptionTextListDataItem item = new DescriptionTextListDataItem();
item.Text = "This is string test";
radDropDownListAdapter.Items.Add(item);
string str1 =
"Name:: " + "test 1" + Environment.NewLine +
"Age:: " + "test 2" + Environment.NewLine +
"ID: : " + "test 3" + Environment.NewLine +
"Scor: " + "test 4" + Environment.NewLine;

item.DescriptionText = str1;
radDropDownListAdapter.SelectedIndex = 0;

Currently i am using VisualStudio2012Light theme and you can see the result in my attach file.
As you can see all my object propertiesrarely seen because it's black and background is blue so my question is how to change this color from black ?

GridView Conditional Formatting Control

Screenshot

From this image, as you can see I have a formatting value condition if the cell is >= 80. If my cell values are strings, how do I control the conversion to an integer value in this case or have control of how this validation takes place? -8000 is nowhere near being >= 80...

Also - How do I control everything else in that Window? It isn't even using my application icon for the form icon. :/

Can the DropDownList have Up and Down arrows?

I am trying to duplicate the "ShowUpDown" feature from the RadDateTimePicker. Ultimately, I want the user to navigate the DropDownList only using the Up and Down arrows, and disable the actual list that opens on the DropDownList. Is this possible?
