BindingManagerBase.Current Property

Definition

When overridden in a derived class, gets the current object.

C#
public abstract object Current { get; }
C#
public abstract object? Current { get; }

Property Value

An Object that represents the current object.

Examples

The following code example prints the value of the Current object in a BindingManagerBase in the CurrentChanged event. The example assumes the data source is a DataTable containing a DataColumn named CustName.

C#
private void Current_Changed(object sender, EventArgs e)
{
    BindingManagerBase bm = (BindingManagerBase) sender;
    /* Check the type of the Current object. If it is not a 
    DataRowView, exit the method. */
    if(bm.Current.GetType() != typeof(DataRowView)) return;

    // Otherwise, print the value of the column named "CustName".
    DataRowView drv = (DataRowView) bm.Current;
    Console.Write("CurrentChanged): ");
    Console.Write(drv["CustName"]);
    Console.WriteLine();
}

Remarks

The Current object contains the value of the current item in the data source. To use the value of the current item, you must cast the item to the Type of the object contained by the DataSource. For example, a DataTable contains DataRowView objects. To determine the type of the current object, use the GetType and ToString methods.

Note

When the DataSource is a DataSet, DataViewManager, or DataTable, you are actually binding to a DataView. Consequently, each Current object is a DataRowView object.
