I want to get the name of the header name of the tab while clicking the tab .
The code by which I am creating the new tab is as followes:
private void mnuSave_Click(object sender, Telerik.Windows.RadRoutedEventArgs e)
        {
            try
            {
                this.txtTabName.Text = string.Empty;
                winNewTabname.Header = "Set Name of Tab";
                winNewTabname.Top = this._mousePosition.Y;
                winNewTabname.Left = this._mousePosition.X - 200;
                winNewTabname.WindowStartupLocation = WindowStartupLocation.Manual;
                winNewTabname.ResizeMode = ResizeMode.NoResize;
                winNewTabname.Closed += new EventHandler<WindowClosedEventArgs>(winNewTabname_Closed);
                winNewTabname.ShowDialog();
            }
            catch (Exception ex)
            {
                Globals.HandleUIExceptions(ex);
            }
        }
        private void winNewTabname_Closed(object sender, WindowClosedEventArgs e)
        {
            if (e.DialogResult == true && !string.IsNullOrEmpty(this.txtTabName.Text.Trim()))
            {
                var found = from Object obj in tabNotes.Items
                            where (obj as RadTabItem).Header.ToString() == this.txtTabName.Text.Trim()
                            select obj;

                if (found.ToList().Count == 0)
                {
                    RadTabItem tabItem = new RadTabItem();
                    tabItem.Tag = this.txtTabName.Text;
                    tabItem.Header = this.txtTabName.Text;
                    tabNotes.Items.Add(tabItem);
                    this.tabNotes.SelectedIndex = tabNotes.Items.Count - 1;
                    RadContextMenu.SetContextMenu(tabItem, _ContextMenu);
                }
                else
                {

                    this.tabNotes.SelectedItem = found.ToList()[0] as RadTabItem;
                }
            }
        }

Now please suggest me how to get the tag name

The TabControl stores the tabs in the Controls collection:
int i = tabControl1.SelectedIndex;
MessageBox.Show(tabControl1.Controls[i].Name);

try Items instead of Controls
If I'm not mistaken, RadTabControl inherits from System.Windows.Controls.ItemsControl which has Items collection to hold the tabs.
int i = tabControl1.SelectedIndex;
MessageBox.Show(tabControl1.Items[i].Name);

I just realized that RadTabControl is not a .NET control
refer to the product documentation at
http://www.telerik.com/help/wpf/telerik.windows.controls.navigation-telerik.windows.controls.radtabcontrol_members.html

one of the control members should let you get the name of the selected tab.
try SelectedItem property:
MessageBox.Show((string)tabControl1.SelectedItem);

The tab control is already created & initialized in the InitializeComponent() method, you shouldn't create another tab control inside winRenameTabname_Closed()
so you need to replace "tabControl1" with the correct object name

The object which is declared earlier is not accessible in the winRenameTabname_Closed()
You can see that in the intellisense.

Hi!

Its not a simple TabControl its custom Control so I can not tell you directly as my internet connection is very slow to download control and test it.

Check this: (Code for rename menu)

RadTabItem item = this.tabNotes.SelectedItem as RadTabItem;
String NameOfTab = item.Header;


Is this helpful ??

Did you check this as well:

RadTabItem item = this.tabNotes.SelectedItem as RadTabItem;
object NameOfTab = item.Header;


You need to check this properties as well from the below link:
http://www.telerik.com/help/wpf/telerik.windows.controls.navigation-telerik.windows.controls.radtabcontrol_properties.html

Items property its a collection and find the current selected tab and search for Header property.
Header property


In this piece of code:

Dim index As Integer
Dim value As RadTabItem
value = tabNotes.Item(index)

Find Header Property under "value".
