Gets or sets a value indicating whether the DataBind method should be called.
Assembly: System.Web (in System.Web.dll)
If you set the property to true when the data-bound control has already begun to render its output to the page, the current HTTP request is not a callback, and you are using the DataSourceID property to identify the data source control to bind to, the DataBind method is called immediately. In this case, the property is not actually set to true.
The following code example demonstrates how the property is used by a derived data-bound control class. After data is retrieved by the GetData method and bound to the control with the PerformDataBinding method, the property is set to false and the MarkAsDataBound method is called to signal that the control has completed binding and no longer requires this property during the current page's lifecycle. This code example is part of a larger example provided for the DataBoundControl class.
