    <p>I suggest you keep some "current state" variables updated so you always have a pointer to the selected Tab Page, and its child control (in the case of a tabbed-notepad emulation discussed here : a TextBox). My preference would be to keep track of the TabPage&lt;>TextBox connections using a Dictionary to avoid having to cast the TextBoxes if they are accessed using the TabPage.Controls route : the following code assumes you have a TabControl named 'tabControl1 on a Form :</p> <pre><code>Dictionary&lt;TabPage, TextBox&gt; dct_TabPageToTextBox; int tabCnt = 1; TabPage currentTabPage; TextBox currentTextBox; </code></pre> <p>So, as you create each new TabPage at run-time you call something like this :</p> <pre><code> private void AddNewTabPage() { if (dct_TabPageToTextBox == null) dct_TabPageToTextBox = new Dictionary&lt;TabPage, TextBox&gt;(); currentTabPage = new TabPage("Page " + tabCnt.ToString()); tabControl1.TabPages.Add(currentTabPage); currentTextBox = new TextBox(); dct_TabPageToTextBox.Add(currentTabPage, currentTextBox); currentTabPage.Controls.Add(currentTextBox); currentTextBox.Dock = DockStyle.Fill; currentTextBox.Text = "sample text for page " + tabCnt.ToString(); tabControl1.SelectedTab = currentTabPage; tabCnt++; } </code></pre> <p>As the end-user changes the selected TabPage you can simply update your current state variables like this :</p> <pre><code>private void tabControl1_SelectedIndexChanged(object sender, EventArgs e) { currentTabPage = tabControl1.SelectedTab; currentTextBox = dct_TabPageToTextBox[currentTabPage]; MessageBox.Show("text in current Tab Page is : " + currentTextBox.Text); } </code></pre> <p>So now have the code that is invoked by your menu choices applied only to the currentTextBox.</p> <p>best, Bill</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
