The page views created within the RadNavigationView have no dock attribute and appear to have a fixed size.
If I set it to autosize it auto sizes to accommodate controls I add, bu,t I want this page to size to the window.
By default it is a small box like this.
I then set autosize and shrinkandgrow which makes it smaller, Adding any controls into this box means the the autosize works but only to the controls. The controls cannot dock to the pageview and the pageview does not dock to the window that I feel it should. I have to manually specify absolute pageview sizes, or manually position larger controls within the window to expand this pageview.
As I resize the form, I want this pageview to resize to it's window to fit the form sizing and cannot see how to do it. There is no dock attribute for these elements. I'm guessing I may need to do this in code somehow to track the window etc. But this feels super-hacky,
Am I missing something basic? to the absolute size of this radpageview - and the pageview has no feature to dock to its container.
The radnavigationview is docked and resizes just fine but its pages do not fill the window.

Im having some trouble adding a spreadsheet to my RadPageViewPage since the spreadsheet requires to be on a thread. This still gives me 'Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.'.
Is there anyone that could explain what im doing wrong here? Thanks.
Edit. Updated the code a bit and this gives me that it requires to be on the STA thread. Its something im not understanding with these threadings in c#.

Dear friends,
I am trying to add run time page in pageview things working well but when I am trying to add windows forum as control it will not show, if I convert it to user control it show in pageview any specific reason behind it?
CustomerMain customerMain = new CustomerMain(); // this one is windows forum if I change it to user control it work fine
customerMain.SelectedCustomerId = CustomerID;
customerMain.Dock = DockStyle.Fill;
customerMain.TopLevel = false;
((Forms.Test.TestCustomerForum)this.ParentForm).ShowParentTab(customerMain, "[" + customer._Owner + "]", CustomerID);
public void ShowParentTab(Control form, string title,int customerID)
{
RadPageViewPage pageOne = new RadPageViewPage();
pageOne.Text = title;
string pageName = customerID.ToString()+ title.Replace(" ","").Trim();
pageOne.Name = pageName;
pageOne.Controls.Add(form);
radPageViewParent .Pages.Add(pageOne);
radPageViewParent.SelectedPage = pageOne;
}
