VS2005中GridView简单应用(CheckBox实现全选)

GridView是VS2005中對VS2003的DataGrid的增強替代控件
下面展示一下它的基本常見應用
效果圖如下：

[查詢]按鈕：查詢數據庫 ，顯示信息Table 並 綁定GridView
//查詢按鈕
protected void btnQue_Click(object sender, EventArgs e)
 {
this.tableInfo.Visible = true;
SqlConnection sqlconn = new SqlConnection("server=localhost;database=db;uid=uid;pwd=pwd;");
sqlconn.Open();
SqlDataAdapter sda = new SqlDataAdapter("select * from table", sqlconn);
DataSet ds = new DataSet();
sda.Fill(ds);
this.grvInfo.DataSource = ds;
this.grvInfo.DataBind();
sda.Dispose();
ds.Dispose();
sqlconn.Close(); 
}

[全選]按鈕：
  //全選
    protected void btnAllCh_Click(object sender, EventArgs e)
    {
        foreach(GridViewRow currow in grvInfo.Rows)
        {
            ((CheckBox)currow.Cells[0].Controls[1]).Checked = true;
        }
    }
類似的[取消全選]的編碼為：
    // 取消全選
    protected void btnNoCh_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow currow in grvInfo.Rows)
        {
            ((CheckBox)currow.Cells[0].Controls[1]).Checked = false;
        }
    }
[明細]按鈕：
該按鈕的操作，要寫在GridView ROW按鈕事件--- RowCommand
    // GridView ROW按鈕事件 RowCommand
    protected void grvInfo_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       if(e.CommandName.Equals("mingxin"))
        {          
        ImageButton lb = (ImageButton)e.CommandSource;
        GridViewRow curgvr = (GridViewRow)lb.Parent.Parent;
        string paraValue = curgvr.Cells[2].Text.ToString();
        //RegisterClientScriptBlock("openmingxin", "<script language='javascript'>window.open(src='mingxin.aspx?pihao="+ paraValue+"','newwindow','');</script>");　　　　
        ClientScript.RegisterClientScriptBlock(this.GetType(), "aa", "<script language='javascript'>alert("+paraValue +"');</script>");
        }
    }     
[刪除]按鈕：
可以在HTML原始檔中加上
<asp:BoundField HeaderText="審核" />
<asp:TemplateField HeaderText="刪除">
<ItemStyle  HorizontalAlign="Center" />                           
<ItemTemplate>
<asp:ImageButton runat="server" ImageUrl="~/image/del.JPG" ID="delid"  CommandName="del"  OnClientClick="return confirm('確實要刪除嗎？');" />
</ItemTemplate>
</asp:TemplateField>
同時也可以如[明細]按鈕在GridView ROW按鈕事件--- RowCommand 對[刪除]點擊按鈕的事件進行服務器端處理!

GridView中 样板列 加入 按钮
============================
前台：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowCommand="GridView1_RowCommand" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
    <Columns>
        <asp:BoundField DataField="personName" />
        <asp:BoundField DataField="personAge" />
        <asp:TemplateField HeaderText="操作">
        <ItemTemplate>
            <asp:Button ID="btn_OK" runat="server" Text="确定"
            CommandArgument='<%# Eval("personName") %>' CommandName="btn_OK" />
            <asp:Button ID="btn_Cancel" runat="server" Text="取消" CommandName="btn_Cancel"
            CommandArgument='<%# Eval("personName") %>' />
        </ItemTemplate>
       </asp:TemplateField>
    </Columns>
</asp:GridView>
后台：
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    //直接利用参数
    string strName = e.CommandArgument.ToString();
    //一种取得当前行的方法
    GridViewRow currRow = (GridViewRow)((Button)e.CommandSource).Parent.Parent;
    string strAge = currRow.Cells[1].Text.ToString();
    if (e.CommandName == "btn_OK")
    {
        this.TextBox1.Text = "确定按钮 " + strName + " " + strAge;
    }
    if (e.CommandName == "btn_Cancel")
    {
        this.TextBox1.Text = "取消按钮 " + strName + " " + strAge;
    }
}
