DataBinder.GetDataItem Method

Definition

Retrieves an object's declared data item.

Overloads

GetDataItem(Object)

Retrieves an object's declared data item.

GetDataItem(Object, Boolean)

Retrieves an object's declared data item, indicating success or failure.

GetDataItem(Object)

Retrieves an object's declared data item.

public static object GetDataItem (object container);

Parameters

container
Object

The object reference against which the expression is evaluated. This must be a valid object identifier in the page's specified language.

Returns

An object that represents the container's declared data item. Returns null if no data item is found or if the container evaluates to null.

Remarks

This method calls the GetDataItem(Object, Boolean) method, ignoring its foundDataItem parameter when returning the result.

An object's data item is identified in one of two ways. If the container object implements the IDataItemContainer interface, the DataItem property identifies the data item, and its value is returned. Otherwise, the method attempts to resolve and return a container property named "DataItem".
