Public ReadOnly Property Current As Object

Visual Basic (Usage)

Dim instance As BindingSource
Dim value As Object

value = instance.Current

[BrowsableAttribute(false)]
public Object Current { get; }

Visual C++

property Object^ Current {
    Object^ get ();
}

Property Value

Type: System..::.Object
An Object that represents the current item in the underlying list represented by the List property, or nullNothingnullptra null reference (Nothing in Visual Basic) if the list has no items.

Remarks

Use the Current property to access the current item, but use the List property to get the entire list. To determine the type of the current object, use the GetType, or ToString methods.

To change the current item, set the Position property to a new integral value, or use one of the navigation methods such as MoveNext.

Examples

The following code example demonstrates the Current property. To run this example, paste the code into a form and call the PopulateBindingSourceWithFonts method from the form's Load event handling method.

Visual Basic

Private WithEvents bindingSource1 As New BindingSource()
Private box1 As New TextBox()


Private Sub PopulateBindingSourceWithFonts()

    bindingSource1.Add(New Font(FontFamily.Families(2), 8.0F))
    bindingSource1.Add(New Font(FontFamily.Families(4), 9.0F))
    bindingSource1.Add(New Font(FontFamily.Families(6), 10.0F))
    bindingSource1.Add(New Font(FontFamily.Families(8), 11.0F))
    bindingSource1.Add(New Font(FontFamily.Families(10), 12.0F))
    Dim view1 As New DataGridView()
    view1.DataSource = bindingSource1
    view1.AutoGenerateColumns = True
    view1.Dock = DockStyle.Top
    Me.Controls.Add(view1)
    box1.Dock = DockStyle.Bottom
    box1.Text = "Sample Text"
    Me.Controls.Add(box1)
    view1.Columns("Name").DisplayIndex = 0
    box1.DataBindings.Add("Text", bindingSource1, "Name")

End Sub

Sub bindingSource1_CurrentChanged(ByVal sender As Object, ByVal e As EventArgs) _
    Handles bindingSource1.CurrentChanged
    box1.Font = CType(bindingSource1.Current, Font)
End Sub

public BindingSource bindingSource1 = new BindingSource();
TextBox box1 = new TextBox();

private void PopulateBindingSourceWithFonts()
{
    bindingSource1.CurrentChanged += new EventHandler(bindingSource1_CurrentChanged);
    bindingSource1.Add(new Font(FontFamily.Families[2], 8.0F));
    bindingSource1.Add(new Font(FontFamily.Families[4], 9.0F));
    bindingSource1.Add(new Font(FontFamily.Families[6], 10.0F));
    bindingSource1.Add(new Font(FontFamily.Families[8], 11.0F));
    bindingSource1.Add(new Font(FontFamily.Families[10], 12.0F));
    DataGridView view1 = new DataGridView();
    view1.DataSource = bindingSource1;
    view1.AutoGenerateColumns = true;
    view1.Dock = DockStyle.Top;
    this.Controls.Add(view1);
    box1.Dock = DockStyle.Bottom;
    box1.Text = "Sample Text";
    this.Controls.Add(box1);
    box1.DataBindings.Add("Text", bindingSource1, "Name");
    view1.Columns[7].DisplayIndex = 0;

}

void bindingSource1_CurrentChanged(object sender, EventArgs e)
{
    box1.Font = (Font)bindingSource1.Current;
