首先在前台设置样式
复制代码 代码如下:
<style type="text/css">
.listover150
{
width:150px;
text-align:left;
overflow:hidden;
text-overflow:ellipsis;//超长设置省略号
white-space:nowrap;
}
</style>

然后在后台GridView中的RowDataBind中进行设置

,附带几句可以改变鼠标移动的样式设置

复制代码 代码如下:
//列表加载处理
protected void gv_showReport_RowDataBound(object sender, GridViewRowEventArgs e)
{

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

//当鼠标移开时还原背景色
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)
{
//设置申请原因字符串显示长度
string strDISC = e.Row.Cells[4].Text.Trim();
e.Row.Cells[4].Text = "<div class=/"listover150/">" + strDISC + "</div>";
e.Row.Cells[4].ToolTip = strDISC;//鼠标放上去显示所有

//设置审批备注字符串截取长度
string str = e.Row.Cells[7].Text.Trim();
e.Row.Cells[7].Text = "<div class=/"listover150/">" + str + "</div>";
e.Row.Cells[7].ToolTip = str;

}
}
