DataGridViewRowPrePaintEventArgs.State 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取当前 DataGridViewRow 的状态。

public:
 property System::Windows::Forms::DataGridViewElementStates State { System::Windows::Forms::DataGridViewElementStates get(); };

public System.Windows.Forms.DataGridViewElementStates State { get; }

member this.State : System.Windows.Forms.DataGridViewElementStates

Public ReadOnly Property State As DataGridViewElementStates

属性值

DataGridViewElementStates

用于指定行的状态的 DataGridViewElementStates 值的按位组合。

示例

下面的代码示例演示如何使用 State 属性确定是否选择了行。 如果选择行，代码将绘制自定义背景。 变量 e的类型为 DataGridViewRowPrePaintEventArgs。 此代码示例是How to： Customize the Appearance of Rows in the Windows 窗体 DataGridView 控件中提供的更大示例的一部分。

// Determine whether the cell should be painted
// with the custom selection background.
if ((e.State & DataGridViewElementStates.Selected) ==
            DataGridViewElementStates.Selected)
{
    // Calculate the bounds of the row.
    Rectangle rowBounds = new Rectangle(
        this.dataGridView1.RowHeadersWidth, e.RowBounds.Top,
        this.dataGridView1.Columns.GetColumnsWidth(
            DataGridViewElementStates.Visible) -
        this.dataGridView1.HorizontalScrollingOffset + 1,
        e.RowBounds.Height);

    // Paint the custom selection background.
    using (Brush backbrush =
        new System.Drawing.Drawing2D.LinearGradientBrush(rowBounds,
            this.dataGridView1.DefaultCellStyle.SelectionBackColor,
            e.InheritedRowStyle.ForeColor,
            System.Drawing.Drawing2D.LinearGradientMode.Horizontal))
    {
        e.Graphics.FillRectangle(backbrush, rowBounds);
    }
}

' Determine whether the cell should be painted with the 
' custom selection background.
If (e.State And DataGridViewElementStates.Selected) = _
    DataGridViewElementStates.Selected Then

    ' Calculate the bounds of the row.
    Dim rowBounds As New Rectangle( _
        Me.dataGridView1.RowHeadersWidth, e.RowBounds.Top, _
        Me.dataGridView1.Columns.GetColumnsWidth( _
        DataGridViewElementStates.Visible) - _
        Me.dataGridView1.HorizontalScrollingOffset + 1, _
        e.RowBounds.Height)

    ' Paint the custom selection background.
    Dim backbrush As New _
        System.Drawing.Drawing2D.LinearGradientBrush(rowBounds, _
        Me.dataGridView1.DefaultCellStyle.SelectionBackColor, _
        e.InheritedRowStyle.ForeColor, _
        System.Drawing.Drawing2D.LinearGradientMode.Horizontal)
    Try
        e.Graphics.FillRectangle(backbrush, rowBounds)
    Finally
        backbrush.Dispose()
    End Try
End If

此属性可用于确定该行在其他状态中是冻结、只读还是已选中。
