Combining textboxes to a buttons

Okey, so heres the deal, we just started on C#, as you might understand I'm a newbie!

I got a input field, four buttons and four outputfields. When I type something in the input field and click button 3 the text is gonna come in outputfield 3. same goes for every other button.

Tekst<asp:TextBox ID="txtbInput" runat="server"></asp:TextBox>
<br />
<asp:Button ID="btnKnapp1" runat="server" Text="Knapp1" OnClick="Button1" />
<asp:Button ID="btnKnapp2" runat="server" Text="Knapp2" OnClick="Button1" />
<asp:Button ID="btnKnapp3" runat="server" Text="Knapp3" OnClick="Button1" />
<asp:Button ID="btnKnapp4" runat="server" Text="Knapp4" OnClick="Button1" />
<br />
En<asp:TextBox ID="txtbUtskrift1" runat="server"></asp:TextBox><br />
To<asp:TextBox ID="txtbUtskrift2" runat="server"></asp:TextBox><br />
Tre<asp:TextBox ID="txtbUtskrift3" runat="server"></asp:TextBox><br />
Fire<asp:TextBox ID="txtbUtskrift4" runat="server"></asp:TextBox>

protected void Button1(object sender, EventArgs e)
{
Button button = (Button)sender;
txtbInput.Text = button.ID;
}

so what this do for me is input the ID of each button into the input field. So I've looked into Switch case, but I cant figure out how to do this! I dont want you guys to simply do the task for me, but give me heads up and point me in the right direction!

Thanks in advance!

Hi

Try this

switch (button.ID) {
case "btnKnapp1":
// do some action
break;
}


Hope this helps. Please let me know if you have got the answer or you think this is not what you are looking for
