示例

下面的代码示例演示如何使用此事件。The following code example illustrates the use of this event. 此示例是DataGridViewRowContextMenuStripNeededEventArgs类概述中提供的一个更大示例的一部分。This example is part of a larger example available in the DataGridViewRowContextMenuStripNeededEventArgs class overview.

private void dataGridView1_DataBindingComplete(object sender,
    DataGridViewBindingCompleteEventArgs e)
{
    // Hide some of the columns.
    dataGridView1.Columns["EmployeeID"].Visible = false;
    dataGridView1.Columns["Address"].Visible = false;
    dataGridView1.Columns["TitleOfCourtesy"].Visible = false;
    dataGridView1.Columns["BirthDate"].Visible = false;
    dataGridView1.Columns["HireDate"].Visible = false;
    dataGridView1.Columns["PostalCode"].Visible = false;
    dataGridView1.Columns["Photo"].Visible = false;
    dataGridView1.Columns["Notes"].Visible = false;
    dataGridView1.Columns["ReportsTo"].Visible = false;
    dataGridView1.Columns["PhotoPath"].Visible = false;

    // Disable sorting for the DataGridView.
    foreach (DataGridViewColumn i in
        dataGridView1.Columns)
    {
        i.SortMode = DataGridViewColumnSortMode.NotSortable;
    }

    dataGridView1.AutoResizeColumns();
}
Private Sub dataGridView1_DataBindingComplete(ByVal sender As Object, _
ByVal e As DataGridViewBindingCompleteEventArgs) _
Handles dataGridView1.DataBindingComplete

    ' Hide some of the columns.
    With dataGridView1
        .Columns("EmployeeID").Visible = False
        .Columns("Address").Visible = False
        .Columns("TitleOfCourtesy").Visible = False
        .Columns("BirthDate").Visible = False
        .Columns("HireDate").Visible = False
        .Columns("PostalCode").Visible = False
        .Columns("Photo").Visible = False
        .Columns("Notes").Visible = False
        .Columns("ReportsTo").Visible = False
        .Columns("PhotoPath").Visible = False
    End With

    ' Disable sorting for the DataGridView.
    Dim i As DataGridViewColumn
    For Each i In dataGridView1.Columns
        i.SortMode = DataGridViewColumnSortMode.NotSortable
    Next i

    dataGridView1.AutoResizeColumns()

End Sub

注解

当数据源的内容更改或DataSource、或BindingContext属性的值发生更改时, DataMember将引发此事件。This event is raised when the contents of the data source change or when the value of the DataSource, DataMember, or BindingContext property changes.

此事件的处理非常有用, 例如, 可以基于内容更新以编程方式调整行和列的大小。Handling this event is useful, for example, to programmatically resize rows and columns based on content updates. 有关详细信息, 请参阅Windows 窗体 DataGridView 控件中的调整大小选项For more information, see Sizing Options in the Windows Forms DataGridView Control.
