GridView中的CheckBox單擊事件(oncheckedchanged)

在GridView中加入 CheckBox控件，想通過單擊選中出現如下圖所示效果：

 

具體做法是：

前台GV部份省掉。只加關鍵的CheckBox部份。

view plaincopy to clipboardprint?
<asp:CheckBox ID="ItemCheckBox" oncheckedchanged="ItemCheckBox_CheckedChanged" AutoPostBack="true" runat="server" /> 
<asp:CheckBox ID="ItemCheckBox" oncheckedchanged="ItemCheckBox_CheckedChanged" AutoPostBack="true" runat="server" />

此代碼需要注意的是:

AutoPostBack="true"

此句的效果是選中后才會執行后台的代碼。

后台代碼：C#

view plaincopy to clipboardprint?
·········10········20········30········40········50········60········70········80········90········100·······110·······120·······130·······140·······150
//單獨選中   
    protected void ItemCheckBox_CheckedChanged(object sender, EventArgs e)   
    {   
        CheckBox chk =(CheckBox)sender;   

        //以下兩句為 選中背景色       第一種方法通過 Parent 獲得GridViewRow   
        DataControlFieldCell dcf = (DataControlFieldCell)chk.Parent;    //這個對象的父類為cell   
        GridViewRow gr = (GridViewRow)dcf.Parent;                   //cell的父類就是row，這樣就得到了該checkbox所在的該行   

        //另外一種NamingContainer獲得 GridViewRow   
        int index = ((GridViewRow)(chk.NamingContainer)).RowIndex;    //通過NamingContainer可以獲取當前checkbox所在容器對象，即gridviewrow   

        string strsql="";   
        string qtable = GVOpen.Rows[index].Cells[4].Text.Trim();   
        string qid = GVOpen.Rows[index].Cells[1].Text.Trim();   
           

        if (chk.Checked)   
        {   
            gr.BackColor = System.Drawing.Color.Green;   
                    }   
        else 
        {   
            gr.BackColor = GVOpen.RowStyle.BackColor;   
        }   
    }
