So you need to handle click event of button. Put necessary code inside the handler of button control.

Also you may have the AutoPostBack set to 'true' in the HTML of your textbox in which case it will do a postback on the enter key.

Delete this option, create a seperate button and do the postback on that

In your HTML...

<asp:Label ID="Label1" runat="server" Text="Enter Value"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<asp:Button ID="btnContinue" runat="server" Text="Continue" onclick="btnContinue_Click" />

And in your code-behind...

protected void btnContinue_Click(object sender, EventArgs e)
{

// validate the textbox...

}
