Enable/Disable Button Based On Empty TextBoxes

I have a form that has a button on it with 2 textboxes. Here is what I need to happen.

I need for the button to be disabled if both textboxes are empty. If the user clears out one and one still has data then still disabled.

Only enable when both boxes have data

Try this and disable the command1 (command1.enable = false):

Private Sub Text1_Change()
  If Text1.Text <> "" And Text2.Text <> "" Then
    Command1.Enable = True
  Else
    Command1.Enable = False
  End If
End Sub
 
Private Sub Text2_Change()
  If Text1.Text <> "" And Text2.Text <> "" Then
    Command1.Enable = True
  Else
    Command1.Enable = False
  End If
End Sub

Create a function like this as given below

and put in following events

textBox1_TextChanged

textBox2_TextChanged

Form1_Load

private void checkdata()
 
{
 
if (textBox1.Text.Trim().Equals("") || textBox2.Text.Trim().Equals(""))
  button1.Enabled = false;
            
else                
   button1.Enabled = true;
 
}

Here is one way of doing it

Private Sub TextChange(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged, TextBox2.TextChanged
If Me.TextBox1.Text.Length = 0 Or Me.TextBox2.Text.Length = 0 Then
Me.Button1.Enabled = False
Else
Me.Button1.Enabled = True
End If
End Sub

for vb6 only code will change to as below

don't forget toput in following events

textBox1_TextChanged

textBox2_TextChanged

Form1_Load

private Sub checkdata
	if(Len(Trim(textbox1.Text))==0||Len(Trim(textbox2.Text))==0)
		button1.Enabled = false;
            
	else
                
		button1.Enabled = true;
 
	Endif
end sub
