C#精髓-- GridView 72般绝技
   GridView实现用“...”代替超长字符串：
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
        {
            DataRowView mydrv;
            string gIntro;
            if (GridView1.PageIndex == 0)
            {
                mydrv = myds.Tables["飞狐工作室"].DefaultView[i];//表名
                gIntro = Convert.ToString(mydrv["家庭住址"]);//所要处理的字段
                GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
            }
            else
            {
                mydrv = myds.Tables["飞狐工作室"].DefaultView[i + (5 * GridView1.PageIndex)];
                gIntro = Convert.ToString(mydrv["家庭住址"]);
                GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
            }
        } 调用的方法：    public string SubStr(string sString, int nLeng)
    {
        if (sString.Length <= nLeng)
        {
            return sString;
        }
        string sNewStr = sString.Substring(0, nLeng);
        sNewStr = sNewStr + "...";
        return sNewStr;
    }
 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //如果是绑定数据行 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ////鼠标经过时，行背景色变 
            //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            ////鼠标移出时，行背景色变 
            //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");            ////当有编辑列时，避免出错，要加的RowState判断 
            //if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            //{
            //    ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");
            //}        }
        if (e.Row.RowIndex != -1)
        {
            int id = e.Row.RowIndex + 1;
            e.Row.Cells[0].Text = id.ToString();
        }    }
}
跟这个差不多吧。参考下

Answer 1

试试可否用 toolTip1.AddControl 

Answer 2

for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
{
if (this.dataGridView1[0, i].Value != null)
{
this.dataGridView1[0, i].ToolTipText = this.dataGridView1[0, i].Value.ToString();
}
}
