winform应用程序中的验证 [英] validations in winform application

问题描述

我的应用程序有10个文本框和10个按钮，



每个文本框一键。

在文本框中输入数据按下按钮。



如此验证文本框。如何操作



以前的应用程序我写了验证，验证事件，在那个应用程序只有一个按钮，所以它工作，



但现在当我进入第一个文本框中的数据单击相应的按钮，然后其他文本框不满足条件，因此他们给出错误。

BY KEEPING if -else in button click event

BY KEEPING if -else in button click event

只验证文本框用这样的相对按钮.. :)

just validate textbox with relative button like this.. :)

public void btnSave_Click(object sender,EventArgs e)
  {

      if (txtNumber.Text != "" || txtNumber.Text != string.Empty)
      {


      }
      else
      {

          MessagBox.Show("Please enter Number...!!! ");
      }

  }
