  1. POHow to handle Copy for multiple controls when adding a ShortcutKey to menu item?
    text
    copied!<p>If I do <strong>not</strong> create an "Edit->Copy" menu item and assign it the shortcut keys "CTRL+C", then I can select a control (RichTextBox, DataGridView, etc..) and hit "CTRL+C" and the control itself will handle the copy. I can copy text out, and paste it into notepad, etc..</p> <p>Now throughout my whole form, I have a lot of controls. But I have a custom control that I want to make clear that I handle Copy functionality for. So I added the ShortcutKey CTRL+C to Edit->Copy, and by default it is set to Enabled.</p> <p>Now, I have to implement an event handler for the 'click' event on that menu item. If I explicitly put in code to handle the copy, then it works:</p> <pre><code>public void menuEditCopy_Click(object sender, EventArgs e) { myCustomControl.Copy(); } </code></pre> <p>However, now Copy does not work on any other type of control. My first inclination was to find out the type of control that has focus, and implement a limited set of copy code for each of them: </p> <pre><code>public void menuEditCopy_Click(object sender, EventArgs e) { if (this.ActiveControl is MyCustomControl) { ((MyCustomControl)this.ActiveControl).Copy(); } else if (this.ActiveControl is RichTextBox) { ((RichTextBox)this.ActiveControl).Copy(); } } </code></pre> <p>etc...</p> <p>However, my controls are added to a SplitContainer, and debugging shows that this.ActiveControl is set to the splitcontainer instance, not the control, even though I know that control is selected.</p> <p>So my last thought is to literally check if every control has focus:</p> <pre><code>public void menuEditCopy_Click(object sender, EventArgs e) { if (myCustomControl.Focused) { myCustomControl.Copy(); } else if (richTextBox1.Focused) { richTextBox1.Copy(); } } </code></pre> <p>I would like to avoid this if possible, it is a lot of controls, and if I add a new control, I would need to update it. Is there a better way of doing this?</p> <p>Thanks</p>
