GridView实现用“...”代替超长字符串：

11.GridView实现用“...”代替超长字符串：

效果图：

解决方法：数据绑定后过滤每一行即可

Code1

    
       1for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
 2{
 3 DataRowView mydrv;
 4 string gIntro;
 5 if (GridView1.PageIndex == 0)
 6 {
 7 mydrv = myds.Tables["飞狐工作室"].DefaultView[i];//表名
 8 gIntro = Convert.ToString(mydrv["家庭住址"]);//所要处理的字段
 9 GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
10 }
11 else
12 {
13 mydrv = myds.Tables["飞狐工作室"].DefaultView[i + (5 * GridView1.PageIndex)];
14 gIntro = Convert.ToString(mydrv["家庭住址"]);
15 GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);
16 }
17}

调用的方法：

Code2

    
       1public string SubStr(string sString, int nLeng)
 2{
 3 if (sString.Length <= nLeng)
 4 {
 5 return sString;
 6 }
 7 string sNewStr = sString.Substring(0, nLeng);
 8 sNewStr = sNewStr + "";
 9 return sNewStr;
10}
