Question

我一直在搜索一天以上的方法来创建可以添加到C＃窗体表格的嵌套网格视图。我发现很多使用ASP.NET的例子，但我找不到任何用C＃完成的例子。我想要一个主/详细Gridview，看起来像以下链接中的那个： http://ilovedeveloper.blogspot.com/2009/05/nested-gridview-using-c.html

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; using System.Data.SqlClient; using System.Configuration; public partial class CS : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { gvCustomers.DataSource = GetData("select top 10 * from Customers"); gvCustomers.DataBind(); } } private static DataTable GetData(string query) { string strConnString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString; using (SqlConnection con = new SqlConnection(strConnString)) { using (SqlCommand cmd = new SqlCommand()) { cmd.CommandText = query; using (SqlDataAdapter sda = new SqlDataAdapter()) { cmd.Connection = con; sda.SelectCommand = cmd; using (DataSet ds = new DataSet()) { DataTable dt = new DataTable(); sda.Fill(dt); return dt; } } } } } protected void OnRowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { string customerId = gvCustomers.DataKeys[e.Row.RowIndex].Value.ToString(); GridView gvOrders = e.Row.FindControl("gvOrders") as GridView; gvOrders.DataSource = GetData(string.Format("select top 3 * from Orders where CustomerId='{0}'", customerId)); gvOrders.DataBind(); } } }

Answer 2

SqlConnection con = new SqlConnection("Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB");

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
// This method is used to bind gridview from database
protected void BindGridview()
{
con.Open();
SqlCommand cmd = new SqlCommand("select TOP 4 CountryId,CountryName from Country", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
gvParentGrid.DataSource = ds;
gvParentGrid.DataBind();

}
protected void gvUserInfo_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
con.Open();
GridView gv = (GridView)e.Row.FindControl("gvChildGrid");
int CountryId = Convert.ToInt32(e.Row.Cells[1].Text);
SqlCommand cmd = new SqlCommand("select * from State where CountryID=" + CountryId, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
gv.DataSource = ds;
gv.DataBind();
}
}

您可以使用模板列来创建嵌套的gridview，您需要在第一行列中的模板列内部构建HTML表，使用自定义绑定使用行数据绑定事件填充主网格行。你应该在html表的第二行内添加嵌套网格视图

Answer 5

使用.on而不是.live更新了jquery

<script type="text/javascript">
    $(document).on("click", "[src*=plus]", function () {
        $(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>");
        $(this).attr("src", "../../_Images/minus.png");
    });
    $(document).on("click", "[src*=minus]", function () {
        $(this).attr("src", "../../_Images/plus.png");
        $(this).closest("tr").next().remove();
    });
</script>
