GridView實現服務器端和客戶端全選的兩種方法

　　代碼很簡單這裡就不累述了看代碼如下

　　<%@ Page Language=C# AutoEventWireup=true %>
<!DOCTYPE html PUBLIC //WC//DTD XHTML Transitional//EN
transitionaldtd>
<script runat=server>
// 計算數據完全可以從數據看取得
ICollection CreateDataSource()
{
    SystemDataDataTable dt = new SystemDataDataTable();
    SystemDataDataRow dr;
    dtColumnsAdd(new SystemDataDataColumn(序號 typeof(SystemString)));
    dtColumnsAdd(new SystemDataDataColumn(學生姓名 typeof(SystemString)));
    dtColumnsAdd(new SystemDataDataColumn(語文 typeof(SystemDecimal)));
    dtColumnsAdd(new SystemDataDataColumn(數學 typeof(SystemDecimal)));
    dtColumnsAdd(new SystemDataDataColumn(英語 typeof(SystemDecimal)));
    dtColumnsAdd(new SystemDataDataColumn(計算機 typeof(SystemDecimal)));

　　for (int i = ; i < ; i++)
    {
      SystemRandom rd = new SystemRandom(EnvironmentTickCount * i); ;
      dr = dtNewRow();
      dr[] = iToString();
      dr[] = 【孟子E章】 + iToString();
      dr[] = SystemMathRound(rdNextDouble() * );
      dr[] = SystemMathRound(rdNextDouble() * );
      dr[] = SystemMathRound(rdNextDouble() * );
      dr[] = SystemMathRound(rdNextDouble() * );
      dtRowsAdd(dr);
    }
    SystemDataDataView dv = new SystemDataDataView(dt);
    return dv;
}

　　protected void Page_Load(object sender EventArgs e)
{
if (!IsPostBack)
{

　　GridViewDataSource = GridViewDataSource = CreateDataSource();
      GridViewDataBind();
      GridViewDataBind();
    }
}

　　protected void Button_Click(object sender EventArgs e)
{
    RetText = ;
    foreach (GridViewRow gvr in GridViewRows)
    {
      CheckBox ch = (CheckBox)gvrFindControl(ItemCheckBox);
      if (chChecked)
      {
        RetText += <li>GridView 您選擇的是（鍵值） + GridViewDataKeys[gvrDataItemIndex]ValueToString();
      }
    }
}

　　protected void CheckAll(object sender EventArgs e)
{
    CheckBox cbx = (CheckBox)sender;
    foreach (GridViewRow gvr in GridViewRows)
    {
      CheckBox ch = (CheckBox)gvrFindControl(ItemCheckBox);
      chChecked = cbxChecked;
    }
}
