I have a text box which I have extended with the AJAX Control Toolkit

  • 0

I have a text box which I have extended with the AJAX Control Toolkit CalendarExtender. When I click on the text box, a calendar appears and I can select a date which then is added to the text box. So far so good.

This text box is used on a Grid View to filter the results in it. This was setup when I added a data source to the grid view.

This works fine other than the fact that after selecting the date in the date control, I then also have to hit enter in the text box for the grid view to update. Can I get to update as soon as the date is selected rather than having to press enter?

    This is because the TextBox_TextChanged event is not being raised. This can only be raised when focus is taken off the textbox, and since focus was put on it, the text has changed.

    One option would be to use jQuery to force a postback whenever text is changed in the textbox.

    Something like:

    $("input.textbox").change(function(){
    __doPostBack();
});

    This article may be of use for forcing Post Back from javascript:
