如何在asp.net类中禁用文本框

Question

 private void txtenable (Boolean txtenable)
 {
     if(txtenable== false)
     {
         txtname.Enabled = false;
         txtTel.Enabled = false;
         txtmobile.Enabled = false;
         txtAdress.Enabled = false;
      }
      else
      {
           txtname.Enabled = true;
          txtTel.Enabled = true;
          txtmobile.Enabled = true;
          txtAdress.Enabled = true;
      }

 }

I want use this class but i can not call textboxes. How can call textbox in class?

First you need to be able to accept the TextBox objects within the class, then you can manipulate them how you see fit. I haven't actually tried this, but this is how I would go about setting it up.

public class YourClass
{
TextBox txtName; 
TextBox txtTel;
TextBox txtMobile;
TextBox txtAddress;
private void txtenable (Boolean txtenable, TextBox txtName, TextBox txtTel, TextBox txtMobile, TextBox txtAddress)
 {
 if(txtenable== false)
 {
     txtName.Enabled = false;
     txtTel.Enabled = false;
     txtMobile.Enabled = false;
     txtAddress.Enabled = false;
  }
  else
  {
      txtName.Enabled = true;
      txtTel.Enabled = true;
      txtMobile.Enabled = true;
      txtAddress.Enabled = true;
  }

}

In order for you to access the textboxes from within your class you will need to pass them such as:

public class OtherClassContainingTextBoxes
{
private void SomeEvent(object sender, EventArgs e){
txtenable(true, txtName, txtTel, txtMobile, txtAddress);
}

However, based on the example provided, I am unsure why you wouldn't do this in a method within the class you have your textboxes.

You could do something on pageload:

 protected void Page_Load(object sender, EventArgs e)
 {
    if (Session["enable"] == false){
       txtenable(false);
    }else{
      txtenable(true);
    }
 } 
private void txtenable (Boolean txtenable)
 {
     if(txtenable== false)
 {
         txtName.Enabled = false;
         txtTel.Enabled = false;
         txtMobile.Enabled = false;
         txtAddress.Enabled = false;
}
     else
     {
         txtName.Enabled = true;
         txtTel.Enabled = true;
         txtMobile.Enabled = true;
         txtAddress.Enabled = true;
      }

 }
