服务器端数据验证

现在有一个方法实现页面所有textbox的数据验证，

public static bool CheckAllItems(Page page,string strFrmName)

page：传过来的page

strFrmName:是页面上面的Form的id

这个方法会检测画面上面所有的textbox的验证

这个方法依赖客户端验证的自定义属性（例如：datatype="string" nullable="no" chname="JobCardNo"），

然后在调用该方法完成简单的数据效验，具体需要可以自己再完善

例子：

       if(pageCommLibrary.CheckAllItems(this,"Form1")==false)

       {

              return;

       }

把CheckAllItems写在公用cs文件里，在需要的页面直接按上面调用既可，具体代码如下（有好的方法望指教）：

public static bool     CheckAllItems(Page page,string strFrmName)
        ...{
            string strDataType="";
            string strNullable="";
            string strChname="";
            string strCheckText="";

            Array array= Array.CreateInstance(typeof(string), 50);

            foreach(System.Web.UI.Control Ctr in page.Controls)
            ...{
                if(Ctr.ID==null)
                ...{
                    continue;
                }

                string ID=Ctr.ID.ToString();

                if(ID.ToLower()==strFrmName.ToLower())
                ...{
                    foreach(System.Web.UI.Control CtrDet in Ctr.Controls)
                    ...{
                        if(CtrDet is System.Web.UI.WebControls.TextBox)
                        ...{
                            System.Web.UI.WebControls.TextBox txtbox=(System.Web.UI.WebControls.TextBox)CtrDet;
                            strCheckText=txtbox.Text.Trim();

                            if(txtbox.ReadOnly==true || txtbox.Enabled==false)
                                continue;

                            if(txtbox.Attributes.Keys.Count<50 && txtbox.Attributes.Keys.Count>0)
                            ...{

                                txtbox.Attributes.Keys.CopyTo(array,0);

                                for(int i=0;i<txtbox.Attributes.Keys.Count;i++)
                                ...{
                                    string strAttItem=array.GetValue(i).ToString();
                                    if(strAttItem.ToLower().Trim()=="datatype")
                                    ...{
                                        strDataType=txtbox.Attributes[strAttItem].Trim();
                                    }
                                    if(strAttItem.ToLower().Trim()=="nullable")
                                    ...{

                                    }
