    <p>I have a problem with a custom property. This is the property in question:</p> <pre><code>[AttributeUsage(AttributeTargets.Property, Inherited = true, AllowMultiple = false)] public class UIProperty : Attribute { public UIProperty(string property, Type target) { Property = property; TargetType = target; } private string property; public string Property { get{return property;} set{property = value;} } private PropertyInfo targetProperty; public PropertyInfo TargetProperty { get { return targetProperty; } protected set { targetProperty = value; } } private Type targetType; public Type TargetType { get{ return targetType; } set{ targetType = value; } } private object target; public object Target { get{return target; } set{ target = value;} } public void SetTargetProperty(PropertyInfo targetPropertyInfo, object target) { targetProperty = targetPropertyInfo; this.target = target; } public object TargetValue { get { return targetProperty.GetValue(target, null); } set { if (!value.Equals(TargetValue)) targetProperty.SetValue(target, value, null); } } } </code></pre> <p>So, if I set the custom attribute with SetTargetProperty after taking out in this way:</p> <pre><code>UIProperty uip = this.GetType (). GetProperty ("name"). GetCustomAttributes (typeof (UIProperty), true) [0] as UIProperty; uip.SetTargetProperty (...); </code></pre> <p>My attribute has correctly set its target and its properties. Nothing is null or not set. But when I go to pick up that property elsewhere in the code everything is back to null as if I had never set ...</p> <p>The classes Attribute are instantiated when i get from a PropertyInfo dynamically or they have a physical instance set to the property?</p> <p>What is wrong?</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.
