<style  type="text/css">  
 .listover150  
{  
width:150px;  
text-align:left;  
overflow:hidden;  
text-overflow:ellipsis;//超長設(shè)置省略號  
white-space:nowrap;  
}  
</style>  

然后在后臺GridView中的RowDataBind中進行設(shè)置

,附帶幾句可以改變鼠標(biāo)移動的樣式設(shè)置

復(fù)制代碼代碼如下:

 //列表加載處理  
   protected void gv_showReport_RowDataBound(object sender, GridViewRowEventArgs e)  
   {  

       if (e.Row.RowType == DataControlRowType.DataRow)  
       {  

           //當(dāng)鼠標(biāo)移開時還原背景色  
           e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");  
           e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#F4FBFF'");  
           e.Row.Attributes.Add("onclick", "this.style.backgroundColor='#e2eaf1'");  
       }  
       if (e.Row.RowType == DataControlRowType.Header)  
       {  
           e.Row.Attributes.Add("style", "background-image:url('../images/grid3-hrow.gif')");  
       }  
       if (e.Row.RowType == DataControlRowType.DataRow)  
       {  
           //設(shè)置申請原因字符串顯示長度  
           string strDISC = e.Row.Cells[4].Text.Trim();  
           e.Row.Cells[4].Text = "<div class=/"listover150/">" + strDISC + "</div>";  
           e.Row.Cells[4].ToolTip = strDISC;//鼠標(biāo)放上去顯示所有  

           //設(shè)置審批備注字符串截取長度  
           string str = e.Row.Cells[7].Text.Trim();  
           e.Row.Cells[7].Text = "<div class=/"listover150/">" + str + "</div>";  
           e.Row.Cells[7].ToolTip = str;  

       }  
   }
