button_click upon pressing Return in TextBox - ASP.NET

Question

I've got an ASP WebForm with 2 Textboxes and 3 Buttons and I want a specific button_click event to be fired whenever I press return whilst in a TextBox - how would I achieve this?

I tried using the TabIndex-Property, unfortunately that actually only seems to work for tabbing, not for pressing return in a TextBox.

Thanks!

Answer 1

Hey everyone, thanks for your answers - I just found the solution, for an aspx-page within a MasterPage I need to set

Form.DefaultButton = myButton.UniqueID;

instead of

Form.DefaultButton = myButton.ID;

which throws an error.

Thanks everyone!

Set the form's AcceptButton to the button you want pressed:

form1.AcceptButton = btnOK;

Answer 3

You can set which button is to be used as the default directly in mark-up of controls, by settings the defaultbutton property value to the ID of the desired button control, try this:

<form id="form1" runat="server" defaultbutton="DefaultButtonId">
    <!-- content -->
</form>
