Hi to all
I have an drop down list, in that there are two fields one is income, expenses and text box . If i select income from the dropdown list then the text box should be disabled, if i select expenses then the textbox should be enabled.

I have tried using this code.
My code
Protected Sub type_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles type.SelectedIndexChanged
If type.SelectedValue.ToString = "Income" Then
vc.Enabled = False
Else
vc.Enabled = True
End If
End Sub

Try this

ASP.NET Syntax (Toggle Plain Text)

Protected Sub type_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles type.SelectedIndexChanged
If type.Text = "Income" Then
vc.Enabled = False
Else
vc.Enabled = True
End If
End Sub

Protected Sub type_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles type.SelectedIndexChanged If type.Text = "Income" Then vc.Enabled = False Else vc.Enabled = True End If End Sub
