从图表到datagridview [英] From chart to datagridview

问题描述

是否可以在Datagridview中显示图表中的数据？我的方案是，如果用户右键单击图表，他们将获得一个选项，以数据网格视图的形式查看与图表关联的数据。



我尝试了什么：



目前我可以正确，它会显示一个空的数据视图。

Hi ,

Is it possible to display the data from a chart in a Datagridview? My scenario is if a user right clicks on a chart they will be given an options to view the data associated with the chart in the form of a datagridview.

What I have tried:

At the moment I can right and it brings up an empty datagriview.

推荐答案

在此了解如何解决您的请求。请记住，这可能不是最有效和最优雅的解决方案。现在，您的工作就是将它与上下文菜单结合在一起:)

Here an idea how you can solve your request. Keep in mind this would be probably not the most efficient and elegant solution. Now it is your Job to bring this together with your context menu :)

private void chartTest_MouseClick(object sender, MouseEventArgs e)
{
    HitTestResult ht = chartTest.HitTest(e.X, e.Y);
    if (ht.Series != null)
    {
        dataGridViewChart.Columns.Clear();
        dataGridViewChart.Columns.Add("ColX", "X");
        dataGridViewChart.Columns.Add("ColY", "Y");
        this.dataGridViewChart.Rows.Clear();

        foreach(var point in ht.Series.Points)
        {
            this.dataGridViewChart.Rows.Add(point.XValue, point.YValues[0]);
        }
    }
}

我希望它有所帮助。

警告：

DataGridView在手动添加行时存在性能问题。使用DataTable，List和DataSource有帮助。

DataGridView has performance problems with manually adding rows. Using DataTable, List and DataSource helps.
