有關於GridView綁定CheckBox的問題

我想要實現的功能：
1.黨我選中checkbox，當前這條記錄的信息顯示到textbox上(根據PRInfoBind())，當前這條紀錄的背景顔色為紅色！
private void PRInfoBind() 
    { 
        int recordCount = 0; 
        string thisPR_ID = ""; 
        string thisMat_ID = ""; 
        string thisSupplier = ""; 
        string thisBuyer = ""; 
        for (int i = 0; i  < this.GridView_PR.Rows.Count; i++) 
        { 
            CheckBox cb_Check = (CheckBox)this.GridView_PR.Rows[i].FindControl("cb_Check"); 
            if (cb_Check.Checked) 
            { 
                this.GridView_PR.Rows[i].BackColor = System.Drawing.Color.Yellow;                 thisPR_ID = this.GridView_PR.Rows[i].Cells[2].Text.ToString().Trim(); 
                thisMat_ID = this.GridView_PR.Rows[i].Cells[3].Text.ToString().Trim(); 
                thisSupplier = ((Label)this.GridView_PR.Rows[i].FindControl("Label1")).Text.ToString().Trim(); 
                string strSql = "select distinct buyer from tbprxz where pr_id='" + thisPR_ID + "' and mat_id='" + thisMat_ID + "'"; 
                thisBuyer = dl.ExcuteScalar(strSql);                 this.DDL_PR_ID.SelectedValue = thisPR_ID.ToString(); 
                this.DDL_Supplier.Items.Insert(0, thisSupplier.ToString()); 
                this.DDL_Buyer.SelectedValue = thisBuyer.ToString(); 
                
            } 
        } 
    }2.當前取消，當前textbox上的信息清空，當前這條紀錄的背景顔色還原！請問大家應該怎麽做？以下就是把上面的問題分開化，但是還是有很多問題
