Showing Default Date and Visible Date with Calendar control

Challenge:

if you are using Calendar control to show Birthday of your friend. So, when you run the application it will show whose b’day is coming in this month or next month or next month …. So, you can be ready for a treat . The Challenge here is how to select that particular date and how to make it visible while user runs the application?

Solution:

You can set SelectedDate of Calendar Control to show date selected like this:

DateTime dtBirthday = getUpcomingBirthday(); //assume this method returns upcoming b’day in DateTime

calBirthday.SelectedDate = dtBirthday.Date; //use Date here else it won’t work

You can set VisibleDate of Calendar Control to show that date:

calBirthday.VisibleDate= dtBirthday.Date; //use Date here else it won’t work

Here DateTime.Date part it too important. Else it won’t work. Do you know why? i know but it’s homework for you guys

Cheers

Form Reset With Validation Control

Challenge:

Reset button won’t clear validation control messages.

Solution:

For that you have to write JS onclick of reset button and do hide it like this:

document.getElementById(“regurlarexpressionID”).style.visibility = “hidden”;

Programmatically Posting Data to ASP .NET Web Applications

Usually what we do. We open a page and fill up a form and submit a form data by pressing “Submit” Button. And after that we get some data/response  as per the logic.  But how to do this programmatically?? — That’s what we have been doing since so long..we faced too many challenges and finally we made it working. You also want to do the same then here we go…

First follow this nice article :

IT WON’T WORK

As someone has already commented on that post — That it throws Internal Server Error(500). But unfortunately no solution has been answered. But don’t worry. i’m here to answer that

Okay, The problem is in your target ASPX page — Means ASPX Page which has form tag. it should have event validation false:

<%@ Page EnableEventValidation=”false” %>

That’s it. It should work now. And if it dosen’t works then try to debug using Fiddler — Really great tool

Okay, So in short to post form data programmatic ally using ASP.NET following steps are required.

1. ViewState Must be passed.

2. In Target page — enableeventvalidation – false.

3. Fiddler must need to install to see what’s going on
