  Hello,

   

  Having some trouble with the tabcontrol.

   

  I want to remember tab visibility and order.  When the user closes the form I save the visible tabitems in a List<string> .

   

  When the form gets loaded I would like to restore the tabs.

  I can control the visibility of the tabs but I can’t find a way to restore the order.

   

  Anybody got a suggestion?

   

  Kind regards,

   

  Tim van Rooijen

  Hey Tim,

  
  

  The tab order of a RadTabStrip is determined by the order of the TabItems in the RadTabStrip.Items collection. In the following code, I save the tab order to a list then restore the tab order in radTabStrip1 based on that list.

  
  

  public partial class Form1 : Form

  {

  List<string> tabOrder = new List<string>();

  public Form1()

  {

  InitializeComponent();

  }

  private void btnChangeTabOrder_Click(object sender, EventArgs e)

  {

  List<RadItem> tabItems = new List<RadItem>((IEnumerable<RadItem>)radTabStrip1.Items);

  radTabStrip1.Items.Clear();

  // Restore the tabs in order in the RadTabStrip

  foreach (string tabName in tabOrder)

  {

  foreach (TabItem item in tabItems)

  {

  if (item.Name == tabName)

  radTabStrip1.Items.Add(item);

  }

  }

  }

  private void btnSaveTabOrder_Click(object sender, EventArgs e)

  {

  // Save order of tabs

  tabOrder.Clear();

  foreach (TabItem item in radTabStrip1.Items)

  tabOrder.Add(item.Name);

  }

  }

  
  

  I hope this helps.

  Hi Robert,
  
  Thank you for sharing your approach with us. I thing there is one more convenient solution -- using Queue<>. In that way you can very easily save and reproduce the TabItems and their order:
  
  

  Queue<TabItem> itemsQueue = new Queue<TabItem>();

  private void saveButton_Click(object sender, EventArgs e)

  {

  this.itemsQueue.Clear();

  for (int i = 0; i < this.radTabStrip1.Items.Count; i++)

  {

  this.itemsQueue.Enqueue((TabItem)this.radTabStrip1.Items[i]);

  }

  this.radTabStrip1.Items.Clear();

  }

  private void restoreButton_Click(object sender, EventArgs e)

  {

  while (this.itemsQueue.Count > 0)

  {

  this.radTabStrip1.Items.Add(this.itemsQueue.Dequeue());

  }

  }
