Question

如何在下面的附加文件后的Child / GrandChild标题上显示行号？

上面的代码仅适用于gridView1_CustomDrawRowIndicator，但不适用于Child的CustomDrawRowIndicator事件。使用该代码的结果是行号以0开头，如何使其以1开头，如此链接https://www.codeproject.com/Tips/835501/Master-Detail-Datagridview和https://www.codeproject.com/Tips/1215736/Master-Detail-Datagridview-in-Csharp

中的结果

    private void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
    {
        GridView gv = (GridView)sender;
        if (e.Info.IsRowIndicator && e.RowHandle >= 0)
        {
            e.Info.DisplayText = e.RowHandle.ToString();
            e.Info.Appearance.Font = new Font("CordiaUPC", 12);
            e.Info.Appearance.Options.UseFont = true;
            e.Info.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
            if (!indicatorIcon)
                e.Info.ImageIndex = -2;
        }
    }

    private void gridView2_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
    {
        GridView gv = (GridView)sender;
        if (e.Info.IsRowIndicator && e.RowHandle >= 0)
        {
            e.Info.DisplayText = e.RowHandle.ToString();
            e.Info.Appearance.Font = new Font("CordiaUPC", 12);
            e.Info.Appearance.Options.UseFont = true;
            e.Info.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
            if (!indicatorIcon)
                e.Info.ImageIndex = -2;
        }
    }           

    private void gridView3_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
    {
        GridView gv = (GridView)sender;
        if (e.Info.IsRowIndicator && e.RowHandle >= 0)
        {
            e.Info.DisplayText = e.RowHandle.ToString();
            e.Info.Appearance.Font = new Font("CordiaUPC", 12);
            e.Info.Appearance.Options.UseFont = true;
            e.Info.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
            if (!indicatorIcon)
                e.Info.ImageIndex = -2;
        }
    }

我尝试了这段代码，但是它是在Columns上添加行号，但是我需要在行标题上显示行号。

    private void gridView1_CustomDrawCell(object sender, RowCellCustomDrawEventArgs e)
    {
        e.DisplayText = e.RowHandle.ToString();
    }

请从此参考资料中尝试这样。 https://www.devexpress.com/Support/Center/Question/Details/T126680/auto-row-number-in-grid

 gridView1.IndicatorWidth = 30;
        void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
        {
            if(e.RowHandle >= 0 )
                e.Info.DisplayText = e.RowHandle.ToString();
        }
