How to conditionally copy the results of one textbox to another textbox depending on the status of a checkbox.

Hello Experts,

I am creating a webform using VB.net to collect information and then email the results to a single recipient. The form asks for patient information and responsible party information. Many times this is the same person. If the checkbox is = true then fill in the responbile party fields with the text of the patient fields.
Thanks in advance for your help.

you need to do a checkbox1_oncheckchanged event on your code behind page

I already have that. Here's my attempt at the code which doesn't work.

Protected Sub chkRPSame_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkRPSame.CheckedChanged
If chkRPSame.Checked = True Then
txtRPFirstName.Text = txtPatFirstName
End If
End Sub

Any ideas?

Sorry. The code is actually...

Protected Sub chkRPSame_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkRPSame.CheckedChanged
If chkRPSame.Checked = True Then
txtRPFirstName.Text = txtPatFirstName.Text
End If
End Sub

But it does't do a thing.

That code should work but only after you have typed in the value in the textbox and then checked the checkbox. It won't work if the checkbox is checked prior to putting a value in the checkbox as the event will never fire.

I think you need something more like this:

Private Sub txtPatFirstName.Text_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtPatFirstName.Text.TextChanged
If chkRPSame.Checked = True Then
txtRPFirstName.Text = txtPatFirstName.Text
Else
txtRPFirstName.Text = ""
End If
End Sub

maralans,
Your'e right. I wasn't giving the control a chance to fire. This was clearly a case of not seeing the forest for the trees. Thanks!
