No Event fire after adding text in code behind

Question

After i use the following code line:

this.txt_welcome_message.Text += "<a href='test' target='_blank'>";

The complete webpage does not fire any event. I tried it with:

CausesValidation="false"

it doesn't help. Here is one of the asp:buttons:

<asp:Button runat="server" ID="btn_special_details_for_welcome_message" Text="Weiter" CssClass="button" OnClick="btn_special_details_for_welcome_message_Click" CausesValidation="false" />

Before I add the text to the asp:TextBox all events firing accordingly, but afterwards no events firing.

Hello your code work on a simple page.

Try to add UseSubmitBehavior="false" on Button propety. I have the same issue not a long and this work for me.
