In Part 1 of this article (Part 1; Part 2; Part 3) we have defined our task and have prepared a basis for creation and testing the Address control. In this part we are going to build the control.
We have decided that our control should includes Label and textBox controls. In order to "force" all controls to behave as a whole unit at change of the sizes follow the following order at designing.
Inside of the Address project from "Windows Forms" tab drag and drop on the Address[Design] user control a panel named panelAddress (fig.4). Drag and drop on the
Figure 4.
panelAddress a label named labelAddress; set the Text property to "Address" and the Dock property to "Left" (fig.5). Drag and drop on the panelAddress a panel named
Figure 5.
panelTextBox; set the Dock property to "Left" (fig 6). Drag and drop on the
panelTextBox a textbox named textBoxAddress; set the Dock property to "Fill"(fig. 7).
OK ! We have finished our design (see fig. 8).
Table 1.
| Control | Name | Text |
| label | labelCityList | Cities |
| label | labelSymbolFind | Symbol |
| label | labelCityFind | City |
| label | labelCity | City |
| label | labelStreet | Street |
| label | labelBuilding | # |
| label | labelApartment | Apartment |
| label | labelEntrance | Entrance |
| label | labelZIP | ZIP |
| groupBox | groupBox1 | Find |
| textBox | textBoxCitySymbolFind | |
| textBox | textBoxCityFind | |
| textBox | textBoxCity | |
| textBox | textBoxStreet | |
| textBox | textBoxBuilding | |
| textBox | textBoxApartment | |
| textBox | textBoxEntrance | |
| textBox | textBoxZIP | |
| listBox | listBoxCity | |
| button | buttonOK | OK |
| button | buttonClean | Clean |
| button | buttonExit | Exit |

The Address control and FormAddress code should includes properties ( such as Street, Apartment, City, DataTable of cities and so on) and methods , that allow to carry out our task.
Namespaces used in the Address control and FormAddress :
using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Windows.Forms;
Add to the Address.cs code page the following code:

int textBox_Height = 26;
//value of the labelAddress width property; default value = 40
int label_Width = 40;
//value of the textBoxAddress Multiline property; default value = "true"
bool textBox_Multiline = true;
