Question

我正在尝试使用链接按钮从转发器中删除子类别。目前，主要类别已删除，但我无法删除子类别。请帮帮我...

    private void BindRepeater()
    {
        DataTable dtCategory = system.GetDataTable("Select * from TBLCATEGORIES where SubCategoryID="+CategoryID); 

        if (dtCategory.Rows.Count > 0)
        {
            rpCategory.DataSource = dtCategory;
            rpCategory.DataBind();
        }
    }

    protected void OnDelete(object sender, EventArgs e)
        {
    //Find the reference of the Repeater Item.
    RepeaterItem item = (sender as LinkButton).Parent as RepeaterItem;


    string constr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        SqlCommand cmd = new SqlCommand("Delete from TBLCATEGORIES where SubCategoryID="+CategoryID); 
        {
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();

            DeleteMsg.Visible = true;

请找到代码，希望对您有所帮助：

   protected void rpCategory_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
            SqlConnection conn;
            SqlCommand comm;
            string connectionString = ConfigurationManager.ConnectionStrings["ShqiptarConnectionString"].ConnectionString;
            conn = new SqlConnection(connectionString);

            conn.Open();

            if (e.CommandName == "Delete")
            {
            comm = new SqlCommand("Delete from TBLCATEGORIES where CategoryID=" + e.CommandArgument, conn);
            comm.ExecuteNonQuery();
            }

            conn.Close();
            conn.Dispose();
            DeleteMsg.Visible = true;

           //Rebind here: this.BindRepeater();
    }
