Question

I have a asp.net Text Box which accepts date in the format MM/DD/YYYY. After entering the date i will hit enter key.if enter key i need to execute server side code.How can we achieve this ?

The problem with Text box is it will fire the Text Changed event only if it looses the focus.

You can use the Panel.DefaultButton property to automatically click a button when the user presses Enter.

For example:

<asp:Panel Id="panel1" runat="server" DefaultButton="btnSubmit">
  <asp:TextBox Id="txtDate" runat="server" />
  <asp:Button Id="btnSubmit" Text="Submit" OnClick="btnSubmit_Click" runat="server" />
</asp:Panel>

If you don't want to show the button, you can set its style="display: none".
