控制GridView中字段的长度，规范数据

前台：

 

       <asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound">

            <Columns>

                <asp:TemplateField>

                    <HeaderTemplate>

                        <input id="cb_head" type="checkbox" name="cb_head" onclick="SelectAll(this,<%=GridView1.ClientID %>);" />

                    </HeaderTemplate>

                    <ItemTemplate>

                        <asp:CheckBox ID="ChkChild1" runat="server" />

                    </ItemTemplate>

                    <ItemStyle HorizontalAlign="Center" />

                    <FooterStyle HorizontalAlign="Center" />

                </asp:TemplateField>

            </Columns>

        </asp:GridView>

后台：

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

    {

        //在RowDataBound事件中调下面的方法

        int[] cellIndexs = new int[4];



        this.setGridViewInfo(e,1, cellIndexs, 11);

    }



    #region

    /// <summary>

    /// 控制GridView中显示字符串的长度 并 在ToolTip中显示全部文本

    /// </summary>

    /// <param name="e">GridViewRowEventArgs e</param>

    /// <param name="cellIndexs">GridView中显示单元格的个数</param>

    /// <param name="maxStrLength">要显示的最大字符串长度</param>

    private void setGridViewInfo(System.Web.UI.WebControls.GridViewRowEventArgs e,int stata_index, int[] cellIndexs, int maxStrLength)

    {

        string CellText = string.Empty;



        //因为我的GridView前一列是CheckBox，所以i从1开始

        for (int i = stata_index; i < cellIndexs.Length; i++)

        {

            CellText = e.Row.Cells[i].Text.Trim();



            if (CellText.Length > maxStrLength)

            {

                e.Row.Cells[i].Text = CellText.Substring(0, maxStrLength - 1) + " <strong style='Color:blue' mce_style='Color:blue'> ... </strong>";



                e.Row.Cells[i].ToolTip = CellText;

            }

        }

    }

    #endregion
