DataGridViewRow.Frozen 属性

  • 参考

定义

命名空间:
System.Windows.Forms
程序集:
System.Windows.Forms.dll

获取或设置一个指示行是否已被冻结的值。

public:
 virtual property bool Frozen { bool get(); void set(bool value); };
[System.ComponentModel.Browsable(false)]
public override bool Frozen { get; set; }
[<System.ComponentModel.Browsable(false)>]
member this.Frozen : bool with get, set
Public Overrides Property Frozen As Boolean

属性值

Boolean

如果行已被冻结，则为 true；否则为 false。

属性
BrowsableAttribute

例外

InvalidOperationException

行位于 DataGridView 控件中，并且是共享行。

示例

下面的代码示例演示如何使用 DataGridViewBand.Frozen 属性，该属性几乎与 类的 DataGridViewRow 属性相同Frozen。 此代码示例是为 DataGridViewBand 类提供的一个更大示例的一部分。

// Freeze the first row.
void Button4_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   FreezeBand( dataGridView->Rows[ 0 ] );
}

void Button5_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   FreezeBand( dataGridView->Columns[ 1 ] );
}

void FreezeBand( DataGridViewBand^ band )
{
   band->Frozen = true;
   DataGridViewCellStyle^ style = gcnew DataGridViewCellStyle;
   style->BackColor = Color::WhiteSmoke;
   band->DefaultCellStyle = style;
}

// Freeze the first row.
private void Button4_Click(object sender, System.EventArgs e)
{

    FreezeBand(dataGridView.Rows[0]);
}

private void Button5_Click(object sender, System.EventArgs e)
{

    FreezeBand(dataGridView.Columns[1]);
}

private static void FreezeBand(DataGridViewBand band)
{
    band.Frozen = true;
    DataGridViewCellStyle style = new DataGridViewCellStyle();
    style.BackColor = Color.WhiteSmoke;
    band.DefaultCellStyle = style;
}

' Freeze the first row.
Private Sub Button4_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button4.Click

    FreezeBand(dataGridView.Rows(0))
End Sub

Private Sub FreezeColumn(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button5.Click

    FreezeBand(dataGridView.Columns(1))
End Sub

Private Shared Sub FreezeBand(ByVal band As DataGridViewBand)

    band.Frozen = True
    Dim style As DataGridViewCellStyle = New DataGridViewCellStyle()
    style.BackColor = Color.WhiteSmoke
    band.DefaultCellStyle = style

End Sub

注解

当用户滚动 DataGridView浏览 时，此属性允许你保留一行或多行重要信息。 冻结行上方的所有行也会被冻结。
