Hi fellow programmers i have a Window form that contains a TabControl which is empty at runtime, i also have a listbox with name of form associated to a user control, when selecting the name from the listbox, i want to be able to check if the tabpage has already been opened before, if yes it does nothing but if that tab has not been opened it opens the new tab.. So far i have tried to compare the text of the selected item in the listbox to the titles of the tabpages already open, but it does not work... What should i do.. Thanks

Hello,

Hope this will help you.. I have a windows form in that Tabcontrol1 is placed. The list box has five values "one", "two","three","four","five". Whenever I select an item in the list box the code will check for the corresponding tabpage is opened or not. If tabpage is not there it will create a tab page and add it to TabPage1. Otherwise if the page is already there it will select the particular page and return. Initially set the tabpages to 0. Hope this helps you to meet your requirement..

C#

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
       {

           foreach (TabPage tp in tabControl1.TabPages)
           {
               //check for tag tile with the selected item in the list box
               if (tp.Text == listBox1.SelectedItem.ToString())
               {
                   //select the particular tabpage
                   tabControl1.SelectedTab = tp;
                   return;
               }
           }
           //if the tabpage is not found in the existing tabs it has to be created
           //crate a new tab
           TabPage newPage = new TabPage(listBox1.SelectedItem.ToString());
           tabControl1.TabPages.Add(newPage);

       }
