asp.net GridView绑定到数组，用数组绑定到<asp:GridView-优快云博客

本文介绍如何使用ASP.NET中的GridView控件绑定数据。包括简单的静态数据绑定及从数据库获取数据并进行复杂处理后绑定的方法。

前台:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowSorting="true"> 
    <Columns> 
        <asp:BoundField DataField="id12333" HeaderText="id"/> 
    </Columns> 
</asp:GridView>

后台：

protected void Page_Load(object sender, EventArgs e)
{
	if (!IsPostBack)
	{
		BindGridView();
	} 
}
void BindGridView()
{
	this.GridView1.DataSource = GetTable();
	this.GridView1.DataBind();
}
DataTable GetTable()
{
	DataTable dt = new DataTable();
	dt.Columns.Add("id12333", typeof(string));
	string[] str = new string[3];//把这个数组改成你的就好了 
	str[0] = "11111111";
	str[1] = "2222";
	str[2] = "3333";
	for (int i = 0; i < str.Length; i++)
	{
		str[i] = str[i].ToString();
	}
	for (int j = 0; j < str.Length; j++)
	{
		DataRow row = dt.NewRow();
		row["id12333"] = str[j];
		dt.Rows.Add(row);
	}
	return dt;
}

下边的例子是从数据库里取出值，把值用split分割后在转成数组的形式绑定到GridView
前台

<asp:GridView ID = "gvwQXLB"  AutoGenerateColumns = "False" Width = "100%" runat = "server" Height="100%">
    <Columns>
        <asp:TemplateField HeaderText="选择">
            <ItemTemplate>
                <asp:CheckBox ID="ckbYHQX" runat="server"  />
            </ItemTemplate>
        </asp:TemplateField>

        <asp:BoundField DataField="bodfViewYHQX_menucaption" HeaderText="用户权限"/> 

        <asp:BoundField DataField="bodfViewQXLB_qxlb" HeaderText="权限类别"/>   

    </Columns>
</asp:GridView>

后台

#region GridView绑定数据，显示用户权限

/// <summary>
/// GridView绑定数据，显示用户权限
/// </summary>
private void gvwBind()
{
	DataSet ds = new DataSet();
	DataTable dt = new DataTable();
	dt.Columns.Add("bodfViewYHQX_menucaption", typeof(string));
	dt.Columns.Add("bodfViewQXLB_qxlb", typeof(string));

	Model.userInfo.UserKey modelQXFP = new Model.userInfo.UserKey();
	BLL.userInfo.UserKey bllQXFP = new BLL.userInfo.UserKey();

	string yhmc;
	yhmc = Request.QueryString["yhmc"];

	ds = (DataSet)bllQXFP.get_YHQXXX(yhmc);

	string[] bodfViewYHQX_menucaption = new string[ds.Tables["dzjc.dzjc_yhqx"].Rows.Count];//开辟数组空间
	string[] bodfViewQXLB_qxlb = new string[ds.Tables["dzjc.dzjc_yhqx"].Rows.Count];
for (int i = 0; i < ds.Tables["dzjc.dzjc_yhqx"].Rows.Count; i++)
	{
		bodfViewYHQX_menucaption = bllQXFP.get_YHQXXX(yhmc).Tables["dzjc.dzjc_yhqx"].Rows[i]["MENUCAPTION"].ToString().Split(',');//MENUCAPTION中数据格式个，“aa,bb,ccc,d,eeee,”
		bodfViewQXLB_qxlb[i] = Convert.ToString(bllQXFP.get_YHQXXX(yhmc).Tables["dzjc.dzjc_yhqx"].Rows[i]["qxlb"]);
	}

	for (int j = 0; j < bodfViewYHQX_menucaption.Length - 1; j++)//获得bodfViewYHQX_menucaption数组长度减一，因为MENUCAPTION中数据存储格式为“aa,bb,ccc,d,eeee,”，最后一个字符为“,”，所以要给长度减一
	{
		DataRow row = dt.NewRow();
		row["bodfViewYHQX_menucaption"] = bodfViewYHQX_menucaption[j];//把分割出来放到数组里的字符串放到DataRow里
		row["bodfViewQXLB_qxlb"] = bodfViewQXLB_qxlb[0];//同一个用户的权限类别相同，所以取下标为0的数组
		dt.Rows.Add(row);
	}

	gvwQXLB.DataSource = dt;//绑定到数组
	gvwQXLB.DataBind();
	ds.Dispose();
}
