C# winform自定义翻页控件详解

C#  winform中自定义的翻页控件,自己设计,供大家参考,具体内容如下

1.主要是使用控件绑定点击事件  

用到的控件分别为picturebox   lable  上一页pbPage_Prev    下一页 pbPage_Next  首页 pbPage_Begin   尾页pbPage_End  是picturebox控件加背景图

“第  页/ 共  页” 是一个lable “labPageInfo”    在lable上面加了一个隐藏的textbox 控件 “txtPageInfo”

2.将这个翻页的功能单独写在用户控件 ucPageTurn 里面  然后在每个页面直接应用就可以了

下面只是把ucPageTurn写了出来

还需要在winform页面上应用上

     }
    }
   }
  }

  public void setInputText(String text)
  {
   txtPageInfo.Text = text;
  }
 }
}

3. 你在资源管文件里面创建的control 文件夹里面,创建了一个用户控件ucPageTurn ,那么在工具栏里面会自动显示你刚刚写的ucPageTurn组件,把它拖到页面上 ,将这个组件的名字叫做ucPages,这样ucpageturn里面的控件就可以进行编辑

//在initControls里面添加textbox输入框的事件
 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;
   }
  }
