gridview 过长字段显示...

1.用一个label来存放你的数据:

1 <asp:TemplateField HeaderText="姓名">

2     <ItemTemplate>

3           <asp:Label ID="Label14" runat="server" Text='<%# Eval("RealName").ToString().Length>=4?Eval("RealName").ToString().Substring(0,4)+"...":Eval("RealName").ToString() %>'  ToolTip='<%# Eval("RealName")%>'></asp:Label>

4       </ItemTemplate>

5       <ItemStyle Width="200px" />

6 </asp:TemplateField>

2.后台事件中编写

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

    {

        for (int g = 0; g < GridView1.Rows.Count; g++)

        {

            GridView1.Rows[g].Cells[7].ToolTip = GridView1.Rows[g].Cells[7].Text;

            if (GridView1.Rows[g].Cells[7].Text.Length > 8)

            GridView1.Rows[g].Cells[7].Text = GridView1.Rows[g].Cells[7].Text.Substring(0, 8) + "...";

        }      

    }
