    <p>I found this code in one of the project developed by an Ex-Employee for custom gridview with custom controls which works fine but I am not sure what exactly it is doing,</p> <p><strong>CODE</strong>:</p> <pre><code>public class aBoundField : ImageField { //here I got some get set properties defined protected override void OnDataBindField(object sender, EventArgs e) { Control control = (Control)sender; PropertyDescriptor propertyA = TypeDescriptor.GetProperties(DataBinder.GetDataItem(control.NamingContainer)).Find("boundField", true); PropertyDescriptor propertyB = TypeDescriptor.GetProperties(DataBinder.GetDataItem(control.NamingContainer)).Find("boundField", true); PropertyAFieldValue = this.GetValue(control.NamingContainer, this._PropertyAField, ref propertyA).ToString(); PropertyBFieldValue = this.GetValue(control.NamingContainer, this._PropertyBField, ref propertyB).ToString(); base.OnDataBindField(sender, e); } </code></pre> <p>What's happening in <code>OnDataBindField</code> method especially when it is getting PropertyDescriptor. I did bit research and figured out that it is a property bag, but if it is a property bag How would it know what value is for property A or Property B in this code.</p> <pre><code> PropertyDescriptor propertyA = TypeDescriptor.GetProperties(DataBinder.GetDataItem(control.NamingContainer)).Find("boundField", true); PropertyDescriptor propertyB = TypeDescriptor.GetProperties(DataBinder.GetDataItem(control.NamingContainer)).Find("boundField", true); </code></pre> <p><strong>What I don't exactly understand is</strong></p> <p>How can <strong>Property Descriptor</strong> gets values of two controls using same code line </p> <pre><code>TypeDescriptor.GetProperties(DataBinder.GetDataItem(control.NamingContainer)).Find("boundField", true) </code></pre> <p>How would above code line will figure out if its for Property A or Property B.</p> <p>I tried to get values from one property descriptor thinking its a property bag but it didn't worked properly.</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.
