Can I disable selection of past dates in an <asp:textbox textmode="data">?

Is it possible to block past dates in an <asp:textbox textmode="Date">?

Solution

  • You could use the min attribute. If you want dynamic behavior (so that it always updates to block dates older than whatever "today" is), you can set the min attribute in your code behind:

    TextBoxArrival.Attributes["min"] = DateTime.Now.ToString("yyyy-MM-dd"); //assumes an <asp:textbox> with ID="TextBoxArrival"

    or use an HTML input field where you can set min directly:

    <input type="date" min="<%= DateTime.Now.ToString("yyyy-MM-dd") %>" value="2013-02-24" />

    There's also a max attribute you could use to restrict the maximum date that could be selected in the field.

    Also don't forget that this is not validation. You should make sure that you perform this validation on your server and not rely on client side.
