C# winform自定義翻頁(yè)控件詳解

更新時(shí)間：2017年09月12日 11:45:28 作者：安東家的安東

這篇文章主要為大家詳細(xì)介紹了C# winform自定義翻頁(yè)控件的方法，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

C# winform中自定義的翻頁(yè)控件，自己設(shè)計(jì)，供大家參考，具體內(nèi)容如下

1.主要是使用控件綁定點(diǎn)擊事件

用到的控件分別為picturebox lable 上一頁(yè)pbPage_Prev 下一頁(yè) pbPage_Next 首頁(yè) pbPage_Begin 尾頁(yè)pbPage_End 是picturebox控件加背景圖

“第頁(yè)/ 共頁(yè)” 是一個(gè)lable “l(fā)abPageInfo” 在lable上面加了一個(gè)隱藏的textbox 控件 “txtPageInfo”

2.將這個(gè)翻頁(yè)的功能單獨(dú)寫(xiě)在用戶控件 ucPageTurn 里面然后在每個(gè)頁(yè)面直接應(yīng)用就可以了

下面只是把ucPageTurn寫(xiě)了出來(lái)

還需要在winform頁(yè)面上應(yīng)用上

3. 你在資源管文件里面創(chuàng)建的control 文件夾里面，創(chuàng)建了一個(gè)用戶控件ucPageTurn ，那么在工具欄里面會(huì)自動(dòng)顯示你剛剛寫(xiě)的ucPageTurn組件，把它拖到頁(yè)面上，將這個(gè)組件的名字叫做ucPages，這樣ucpageturn里面的控件就可以進(jìn)行編輯

//在initControls里面添加textbox輸入框的事件
 private void initControls()
  
 {
  ucPages.InputTextBox.KeyPress +=new KeyPressEventHandler(ucPages_KeyPress);
   ucPages.PageChanged += new Pku.CFM.Controls.ucPageTurn.PageChangedHandle(ucPages_PageChanged);
}

 private void ucPages_KeyPress(object sender, KeyPressEventArgs e)
  {
   if (13 == e.KeyChar)
   {
    int intReturn = SysDefine.NOTHING;
    String strInputText = ucPages.Text.ToUpper();
    if (SysDefine.FAILED == intReturn)
    {
     MessageBox.Show(this.ErrorText, "信息", MessageBoxButtons.OK, MessageBoxIcon.Warning);
    }
    
    String pageInputText = ucPages.InputText;
    int page = 0;
    try
    {
     page = int.Parse(pageInputText);
    }
    catch
    {
     page = 1;
    }
    ucPages.CurPageIndex = page;
    if (SysDefine.FAILED == refreshList(page, strInputText))
    {
     MessageBox.Show(this.ErrorText, "信息", MessageBoxButtons.OK, MessageBoxIcon.Warning);
    }
   }
  }

 private void ucPages_PageChanged(int oldPage, int newPage, EventArgs e)
  {
   int intReturn = SysDefine.NOTHING;

   String strInputText = ucPages.Text.ToUpper();
   intReturn = refreshList(newPage, strInputText);
   if (SysDefine.FAILED == intReturn)
   {
    MessageBox.Show(this.ErrorText, "信息", MessageBoxButtons.OK, MessageBoxIcon.Warning);
    return;
