怎样控制字符的显示个数?希望两分钟分搞定,全靠各位大哥大姐了.......

一个gridview绑定数据后,每条记录的标题字数太多,比如有20个字,但列宽只能显示15个字,怎么让它少显示几个字数,然后用...代替呢?

急,,,大家抓紧时间,,快下班了.

#region 用“...”代替超长字符串调用的方法
public string SubStr(string sString, int nLeng)
{
if (sString.Length <= nLeng)
{
return sString;
}
string sNewStr = sString.Substring(0, nLeng);
sNewStr = sNewStr + "...";
return sNewStr;
}
#endregion

//处理备注这一行的数据
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

mydrv = ds.Tables[0].DefaultView[i];//表名
gIntro = Convert.ToString(mydrv["room_test"]);//所要处理的字段(备注这一列)
GridView1.Rows[i].Cells[9].Text = SubStr(gIntro, 2);
}
else

mydrv = ds.Tables[0].DefaultView[i + (GridView1.PageSize * GridView1.PageIndex)];
gIntro = Convert.ToString(mydrv["room_test"]); //GridView1.Rows[i].Cells[9].TemplateSourceDirectory.Insert(i,gIntro);
GridView1.Rows[i].Cells[9].Text = SubStr(gIntro, 2);
