我想在文本框中输入EmpId的基础上，还应填写该特定emp形式的所有其他文本框

Question

我希望当用户自动输入emp id时（根据用户填写的特定id），该特定员工的所有其他信息应填写在表格中，并应保持禁用状态，直到emp按下编辑按钮为止。 / p>

我设计了一个注册表，其中有以下文本框和3个按钮 emp ID 国籍 宗教 性别

保存按钮编辑按钮清除按钮

我已经实现了保存按钮和清除按钮的编码。填写表单后，当用户单击“保存”按钮时，数据将存储在数据库表中

预期的输出-当用户输入EmpId时，表单中存在的所有其他文本框应自动填充（从现有数据库中填充），并应保持禁用状态，直到用户单击编辑按钮为止

实际结果-用户输入emp id，然后他必须填写所有文本框。它不会自动更新。当用户单击“保存”按钮时，数据将注册到表中，而“清除”按钮也会清除所有外部框。
