效果圖
網上查了很多例子自己結合和修改了一下。最下方的分頁跳轉是dev的datapager控件。控件的屬性事件自己研究一下。
代碼如下
public partial class MMDefinitionQueryForm : Form
{
private IMMwDefinitionsCoBO immwDefinitionsCoBO_0;
private IMMwDefVersCoBO immwDefVersCoBO_0;
public MMDefinitionQueryForm()
{
this.InitializeComponent();
this.immwDefinitionsCoBO_0 = ObjectContainer.BuildUp<IMMwDefinitionsCoBO>();
this.immwDefVersCoBO_0 = ObjectContainer.BuildUp<IMMwDefVersCoBO>();
Resultlist.OptionsBehavior.ReadOnly = true; //只讀
Resultlist.OptionsBehavior.Editable = false; //不可編輯
}
//頁行數
//public int pagesize = 1;
//當前頁
public int pageIndex = 1;
//總頁數
public int pageCount;
//排序規則
public string ordername = "DefID";
public string order = "ASC";
public int orderint = 0;
public string DefID = null;//設備編號
public string version = null;//物料版本
public string DefPK = null;//設備識別碼
//public string EqpDefName;
//分頁及數據綁定

先寫這么多有問題和建議或者哪里不明白的地方可以直接私聊我，如果覺得有幫助幫我點個贊我讓我有動力繼續發博客謝謝了。
