请教一下各位大侠!如何使用代码调整dataGridView单元格的大小!dataGridView1.Rows[1].Height = 50;
?????????? --------------------编程问答-------------------- 单元格的大小不就是行和列的大小决定的啊.所以你调整了行高和列宽就可以达到目的了! --------------------编程问答-------------------- 行和列是我用代码生成的，可是我不懂怎么用代码控制列的宽度! --------------------编程问答-------------------- using System;

dataGridView1.Rows[1][0].Width =50; 这样试试看
补充：.NET技术 , C#
