Introduction

This is a Custom Control that I have created, this is my first control. What this control will do? I guess this is very simple; it will just change the Month name on button up or down.
In our Sample Application we will just demonstrate how to use it.

Create a Silverlight Project

Designing the Application

Here is an idea; we will have two buttons up and down, and one text box which will carry the text. I have used Blend 3 to design this. First I have created a path (using the Pen Tool) a triangle and made a copy of it so that I can use it for its reverse side.

Then I Converted the Path into Buttons, and made two Buttons out of it; Up Button and Down Button. They will look similar to the following.

Adding a TextBox Control

Adding a text box is not that tough but I have made some changes to look familiar with the control. The following xaml code for the whole design will help you.

Logic to Display Month On Button Click

I have used the following logic:

private void btnDown_Click(object sender, RoutedEventArgs e)
        {
            switch (txtMonth.Text)
            {
                case "January":
                    txtMonth.Text = "December";
                    break;
                case "February":
                    txtMonth.Text = "January";
                    break;
                case "March":
                    txtMonth.Text = "February";
                    break;
                case "April":
                    txtMonth.Text = "March";
                    break;
                case "May":
                    txtMonth.Text = "April";
                    break;
                case "Jun":
                    txtMonth.Text = "May";
                    break;
                case "July":
                    txtMonth.Text = "Jun";
                    break;
                case "August":
                    txtMonth.Text = "July";
                    break;
                case "September":
                    txtMonth.Text = "August";
                    break;
                case "October":
                    txtMonth.Text = "September";
                    break;
                case "November":
                    txtMonth.Text = "October";
                    break;
                case "December":
                    txtMonth.Text = "November";
                    break;
                default:
                    break;
            }
      }

        private void btnUp_Click(object sender, RoutedEventArgs e)
        {
            switch (txtMonth.Text)
            {
                case "January":
                    txtMonth.Text = "February";
                    break;
                case "February":
                    txtMonth.Text = "March";
                case "March":
                    txtMonth.Text = "April";
                    break;
                case "April":
                    txtMonth.Text = "May";
                    break;
                case "May":
                    txtMonth.Text = "Jun";
                    break;
                case "Jun":
                    txtMonth.Text = "July";
                    break;
                case "July":
                    txtMonth.Text = "August";
                    break;
                case "August":
                    txtMonth.Text = "September";
                    break;
                case "September":
                    txtMonth.Text = "October";
                    break;
                case "October":
                    txtMonth.Text = "November";
                    break;
                case "November":
                    txtMonth.Text = "December";
                    break;
                case "December":
                    txtMonth.Text = "January";
                    break;
                default:
                    break;
            }
        }
