    <p>how to give same property to all textboxes present in the same form.</p> <pre><code> foreach (var textbox in this.Controls.OfType&lt;TextBox&gt;()) { textbox.ContextMenu = new ContextMenu(); } </code></pre> <p>The above code works only if the textboxes are not in nested format.</p> <p>In my project I have multiple tabpages in tabcontrol. so i cant implement the above code. but i can implement the below code:</p> <pre><code> foreach (TextBox textbox in this.Controls.OfType&lt;TabControl&gt;().SelectMany(tc =&gt; tc.Controls.OfType&lt;TabPage&gt;().SelectMany(page =&gt; page.Controls.OfType&lt;TextBox&gt;()))) { textbox.ContextMenu = new ContextMenu(); } foreach (var textbox in this.tabCarInsurance.Controls.OfType&lt;TextBox&gt;()) { textbox.ContextMenu = new ContextMenu(); } foreach (var textbox in this.tabHomeLoans.Controls.OfType&lt;TextBox&gt;()) { textbox.ContextMenu = new ContextMenu(); } foreach (var textbox in this.tabRetirement.Controls.OfType&lt;TextBox&gt;()) { textbox.ContextMenu = new ContextMenu(); } </code></pre> <p>Here I am implementing for each tabControl. which still i dont like (because I have more tab pages to take care of). Is there anyway to reduce the above code.</p> <p>I tried the below code: (<em>not working</em>)</p> <pre><code> foreach (var textbox in this.Controls.OfType&lt;TabControl&gt;().OfType&lt;TextBox&gt;()) { textbox.ContextMenu = new ContextMenu(); } </code></pre> <p>I got the above code knowledge from my <a href="https://stackoverflow.com/q/12894451/1577396">previous question</a>.</p> <p>Please Help <br>Thanks in Advance.</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.
