Body
I am working on creating a thread safe control for my windows forms application. I understand I can set the text on a control thread safe by using the following code: <pre><code>private delegate void SetTextD(Control control, string value); private static void SetText(Control control, string value) { if(control.InvokeRequired) { control.Invoke(new SetTextD(SetText), new object[] {control, value}); } else { control.Text = value; } } </code></pre> Then in my form code i can call: <pre><code>SetText(lblStatus, "Updating..."); </code></pre> My goal is to create a custom control, which inherits Label. Then inside this class, on the Text property I can just call: lblStatus.Text = "Updating..." Then it will automatically do the proper thread safe code. Here is the code that I have in my class: <pre><code>public class ThreadSafeLabel : Label { private delegate string GetTextD(); private delegate void SetTextD(string value); private string GetText() { if (InvokeRequired) { return (string)Invoke(new GetTextD(GetText)); } return Text; } private void SetText(string value) { if(InvokeRequired) { Invoke(new SetTextD(SetText), new object[] {value}); } else { Text = value; } } public override string Text { get { return GetText(); } set { SetText(value); } } } </code></pre> Now, when I attempt to add this control to my form, it crashes VS 2008. I was thinking that maybe it had to do with setting the initial text property when you add it to the form, but not sure. Any thoughts on what I might be doing wrong or what I might be missing? If something is not clear, please ask. Thanks!

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.
