关于GridView的使用涉及很多,网络上零零散散的有一些,为了让自己使用方便,也为了大家能很好的学习与工作,我把网络上的GridView使用方法收集了一些
GridView自带的分页功能实现:
要实现GrdView分页的功能 操作如下: 1、更改GrdView控件的AllowPaging属性为true。 2、更改GrdView控件的PageSize属性为 任意数值(默认为10) 3、更改GrdView控件的PageSetting->Mode为Numeric等(默认为Numeric)该属性为分页样式。 GridView属性设置好了,从页面上也能看到分页样式。
现在开始实现分页的功能:
1、在<<asp:GridView ID=......>后添加,OnPageIndexChanging="GridView1_PageIndexChanging" 2、在对应的aspx.cs中添加: protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; InitPage(); //重新绑定GridView数据的函数 } 3、 GridView1.PageIndex = e.NewPageIndex; 完了之后再重新绑定一下GridView。
GridView添加CheckBox列实现全选/全部取消功能
首先GridView编辑模版,在模板上添加CheckBox控件,之后将新添加列字段转换为TemplateFiled
后台代码: 复制代码 代码如下: using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient;
public partial class Default5 : System.Web.UI.Page { SqlConnection sqlcon; string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa"; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { bind(); } } protected void CheckBox2_CheckedChanged(object sender, EventArgs e) { for (int i = 0; i <= GridView1.Rows.Count - 1; i++) { CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1"); if (CheckBox2.Checked == true) { cbox.Checked = true; } else { cbox.Checked = false; } } } protected void Button2_Click(object sender, EventArgs e) { sqlcon = new SqlConnection(strCon); SqlCommand sqlcom; for (int i = 0; i <= GridView1.Rows.Count - 1; i++) { CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1"); if (cbox.Checked == true) {
string sqlstr = "delete from 飞狐工作室 where 身份证号码='" + GridView1.DataKeys[i].Value + "'"; sqlcom = new SqlCommand(sqlstr, sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); } } bind(); } protected void Button1_Click(object sender, EventArgs e) { CheckBox2.Checked = false; for (int i = 0; i <= GridView1.Rows.Count - 1; i++) { CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1"); cbox.Checked = false; } } public void bind() { string sqlstr = "select top 5 * from 飞狐工作室"; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, "tb_Member"); GridView1.DataSource = myds; GridView1.DataKeyNames = new string[] { "身份证号码" }; GridView1.DataBind(); sqlcon.Close(); } }
前台主要代码: 复制代码 代码如下: <asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False" CellPadding="3" Font-Size="9pt" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"> <FooterStyle BackColor="White" ForeColor="#000066" /> <Columns> <asp:TemplateField> <ItemTemplate> <asp:CheckBox ID="CheckBox1" runat="server" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="身份证号码" HeaderText="用户ID" SortExpression="身份证号码" /> <asp:BoundField DataField="姓名" HeaderText="用户姓名" SortExpression="姓名"/>
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" SortExpression="家庭住址"/>
</Columns> <RowStyle ForeColor="#000066" /> <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" /> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> </asp:GridView> <asp:CheckBox ID="CheckBox2" runat="server" AutoPostBack="True" Font-Size="9pt" OnCheckedChanged="CheckBox2_CheckedChanged" Text="全选" /> <asp:Button ID="Button1" runat="server" Font-Size="9pt" Text="取消" onClick="Button1_Click" /> <asp:Button ID="Button2" runat="server" Font-Size="9pt" Text="删除" onClick="Button2_Click" />
