在 DataGridView 的行标题中显示行号 [英] Show row number in row header of a DataGridView

问题描述

是否可以在 DataGridView 的行标题中显示行号?

Is it possible to show row number in the row header of a DataGridView?

我正在尝试使用此代码，但不起作用:

I'm trying with this code, but it doesn't work:

    private void setRowNumber(DataGridView dgv)
    {
        foreach (DataGridViewRow row in dgv.Rows)
        {
            row.HeaderCell.Value = row.Index + 1;
        }
    }

我是否必须设置一些 DataGridView 属性?

Do I have to set some DataGridView property?

推荐答案

好像没有把它变成字符串.试试

It seems that it doesn't turn it into a string. Try

row.HeaderCell.Value = String.Format("{0}", row.Index + 1);
