DotNetNuke MVP Module Development: Tip #2 Disable AutoDataBind

In DotNetNuke MVP Module Development: Tip #1 The AutoDataBind Property I suggested to use AutoDatBind to automatically bind up the user control.  However, there are times when no binding should occur.  For example, when a Cancel button is clicked the view should not be bound.  AutoDataBind should be disabled when no model is need.

protected void cmdCancel_Click(object sender, EventArgs e)
{
    try
    {
        AutoDataBind = false;
        OnCancel();
    }
    catch (Exception exc)
    {
        Exceptions.ProcessModuleLoadException(this, exc);
    }
}

Quick Tip: Use JQuery to submit a TextBox.

imageSubmitting a search box when <Enter> is pressed is a nice usability feature to provide.  Unfortunately, ASP.NET Web Forms and its requirement for a single <form> tag breaks this expected behavior when there is more than one submit button on the page.   This can be easily fixed with a JavaScript and JQuery.   Listening to the keydown event on the TextBox the Go submit button can be triggered when <Enter> is pressed.

jQuery("#searchTextBox").keydown(function (event) {
    if (event.keyCode && event.keyCode == '13') {
        jQuery("#searchButton").click();
        return false;
    } else {
        return true;
    }
});
