GridView控件的应用

GridView控件的运用： 

 

 <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
            CellSpacing="1" Height="1px" PageSize="26" Width="500px" CssClass="txt" 
                        OnPageIndexChanging="GridView1_PageIndexChanging" 
                        OnRowDeleting="GridView1_RowDeleting" OnRowDataBound="GridView1_RowDataBound" 
                        onselectedindexchanged="GridView1_SelectedIndexChanged">
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="ID" />
                <asp:BoundField DataField="title" HeaderText="新闻标题" />
                <asp:BoundField DataField="Type" HeaderText="新闻类别" />
                <asp:BoundField DataField="IssueDate" HeaderText="发布日期" />
                <asp:HyperLinkField HeaderText="编辑" Text="编辑" DataNavigateUrlFields="id" 

                  DataNavigateUrlFormatString="Edit.aspx?id={0}" Target="main" />
                <asp:CommandField ShowDeleteButton="True" />
            </Columns>
        </asp:GridView>

 

DataNavigateUrlFields="id" 是用于提交的字段。

 

//如果要提交两个字段，则代码如下：

//DataNavigateUrlFields="id,name"
//DataNavigateUrlFormatString ="Edit.aspx??id={0}&name={1}" 。

 

这样在RE_HperLink.aspx文件中 sql= "select * from sudents wherr id='"+request.querystring("id")+"'" 就能运行成功了。

 

 “Edit.aspx?id="{0}"〉这是url传参的方法，把变量id的值传到下一个页面中，变量的名称可以随便起，只要你知道用了哪个名字就可以，因为，你在Edit.aspx里id通过   string   questionID   =   Request.QueryString["id"];来获取它.

 

当有多个页面时，点击下标页面变化的代码：

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        GridView1.DataBind();
    }
