Question

I have a textbox that will collect the ip address from the user. I double click in the designer to take me to my .CS code it takes me to the correct location for _TextChanged.

One thing I notice it that event is grayed out and say it’s not used, even though I click on it and allowed me to enter code. I tryed moving it outside of the partial class, it just made all the controls unseeable. I have no errors at design time.

Make sure your text box has an ontextchanged property with the method name from your code behind.

<asp:TextBox ID="TextBox1" runat="server" ontextchanged="TextBox1_TextChanged"></asp:TextBox>

Inside your webform partial class:

    protected void TextBox1_TextChanged(object sender, EventArgs e)
    {

    }
