Performs data binding against each of the defined DataBindingItems defined on the DataBinder control. This binds all BindingSources to the specified control properties.

Typically DataBind is called in the Page_Load() of the page cycle and only when the page originally loads - ie. (if !Page.IsPostPack). Subsequent page hits post back values so you typically do not want to rebind values to POST form variables on each hit.

<> Invoice.Load(id); // load data to bind

// bind only on first load or if the product is changed if (!IsPostBack || IsProductChange) DataBinder.DataBind(this);

// Manually bind this control always - it's ReadOnly and so doesn't post back DataBinder.GetDataBindingItem(txtPk).DataBind(); <>

Some controls - non-Postback, or read only controls for example - you will want to rebind explicit each time so make sure those are bound explicitly outside of the !IsPostBack block.
