方法3、在数据库里面直接栽掉...
select case when len(field)> 10 then left(field,10)+'...' else field end as news_name,news_id from tablename
方法4、 在RowDataBound方法中：
如果是BoundField，则：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.Cells[2].Text.Length > 10)
{
e.Row.Cells[2].Text = e.Row.Cells[2].Text.Substring(0, 10) + "...";
}
else
{
e.Row.Cells[2].Text=e.Row.Cells[2].Text
}
}
}
如果是TemplateField，则：
方法5、 如果是 TemplateField 列，可以直接帮定时操作
<asp:TemplateField HeaderText="Hehe">
<ItemTemplate>
<asp:Label runat="server" Text= <%#Eval("job_id").ToString().Substring(0,10)+"..."%> >
</asp:Label>
</ItemTemplate>
</asp:TemplateField>

protected void GridView1_RowDataBound ( object sender, GridViewRowEventArgs e )
{
if ( e.Row.RowType == DataControlRowType.DataRow )
{
if ( ( ( Label ) e.Row.Cells [    2   ].FindControl ( "Hehe" ) ).Text   .Length >    10 )
{
( ( Label ) e.Row.Cells [   2   ].FindControl ( "Hehe" ) ).Text = ( ( Label ) e.Row.Cells [    2   ].FindControl ( "Hehe" ) ).Text.Substring ( 0, 10 ) + "...";
}
