public System.Windows.Forms.DataGridView.HitTestInfo HitTest (int x, int y);
member this.HitTest : int * int -> System.Windows.Forms.DataGridView.HitTestInfo
Public Function HitTest (x As Integer, y As Integer) As DataGridView.HitTestInfo

参数

x
Int32

x 坐标。The x-coordinate.

y

示例

下面的代码示例演示如何使用此方法。The following code example illustrates the use of this method. 此示例是 Columns 属性参考主题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 Columns property reference topic.

private DataGridViewCell clickedCell;

private void dataGridView1_MouseDown(object sender, MouseEventArgs e)
{
// If the user right-clicks a cell, store it for use by the shortcut menu.
    if (e.Button == MouseButtons.Right)
    {
        DataGridView.HitTestInfo hit = dataGridView1.HitTest(e.X, e.Y);
        if (hit.Type == DataGridViewHitTestType.Cell)
        {
            clickedCell =
                dataGridView1.Rows[hit.RowIndex].Cells[hit.ColumnIndex];
        }
    }
}
Private clickedCell As DataGridViewCell

Private Sub dataGridView1_MouseDown(ByVal sender As Object, _
    ByVal e As MouseEventArgs) Handles dataGridView1.MouseDown

    ' If the user right-clicks a cell, store it for use by the 
    ' shortcut menu.
    If e.Button = MouseButtons.Right Then
        Dim hit As DataGridView.HitTestInfo = _
            dataGridView1.HitTest(e.X, e.Y)
        If hit.Type = DataGridViewHitTestType.Cell Then
            clickedCell = _
                dataGridView1.Rows(hit.RowIndex).Cells(hit.ColumnIndex)
        End If
    End If

End Sub

注解

您可以使用此方法来确定 @no__t 0 控件的哪个部分位于指定的坐标处。You can use this method to determine which part of the DataGridView control is located at the specified coordinates. 例如,您可以调用此方法-指定鼠标单击的坐标,以确定单击的单元格的行索引和列索引,或者是否单击了标题单元或滚动条。For example, you can call this method - specifying the coordinates of a mouse click - to determine the row and column indexes of the clicked cell or whether a header cell or scroll bar was clicked.
