This quick start demonstrates how to create a travel registration form by using Input controls. Complete the following steps to set up the application, configure the controls, and populate the required data.
The completed travel registration form appears as follows:

Set Up the Application
Create a Windows Forms App (.NET) project.
In Visual Studio, select Project > ProjectName Properties, and then select .NET 6.0 or later from the Target Framework list.
Install the C1.Win.Input NuGet package. After the package is installed, the Input controls appear in the Toolbox when the form is open in the designer.
Add and Configure Input Controls
Add the Input controls required for the travel registration form and configure their properties.
In the form designer, drag the required controls, including Label and RadioButton controls, from the Toolbox onto the form.
Arrange the controls to create the required layout.

Configure the Name and Text properties as shown in the following table.
Control | Name property | Text property |
|---|---|---|
c1Label1 | lblTitle | Travel Registration Form |
c1Label2 | lblName | Name |
c1TextBox1 | txtName | |
c1Label3 | lblGender | Gender |
c1RadioButton1 | radioBtnMale | Male |
c1RadioButton2 | radioBtnFemale | Female |
c1Label4 | lblTravelTo | Country |
c1SplitButton1 | splitBtnCountry | |
c1Label5 | lblPurpose | Purpose |
c1ComboBox1 | cmbPurpose | |
c1Label6 | lblVisa | Visa Status |
c1CheckBox1 | chkVisa | Stamped |
c1Label7 | lblPic | Photo |
c1Button1 | btnSelectPic | Browse |
c1PictureBox1 | picBoxMain | |
c1Label8 | lblNumofDays | Duration (in days) |
c1RangeSlider1 | rgSliderDays | |
c1Label9 | lblTravellers | Number of Travelers |
c1NumericEdit1 | numEditTravellers | |
c1Label10 | lblMin | rgSliderDays.Minimum.ToString(); |
c1Label11 | lblMax | rgSliderDays.Maximum.ToString(); |
c1Label12 | lblProf | Profession |
c1DropDownControl1 | dropdownControl | dataGridView.CurrentCell.Value.ToString(); |
DataGridView | dataGridView | |
c1ColorPicker1 | colorPicker | |
c1MaskedTextBox1 | MaskedTextBox |
Set the Font property of lblTitle to Georgia, 18 pt, Bold.
Set the Value property of numEditTravellers to 1.
Configure rgSliderDays to use a range of 5 through 30 days. Set the lower value to 5, the upper value to 30, and configure the slider increments and scrolling behavior as required.
Display the minimum and maximum slider values in lblMin and lblMax.
//configure range slider control
rgSliderDays.LowerValue = 5D;
rgSliderDays.Maximum = 30D;
rgSliderDays.Minimum = 5D;
rgSliderDays.LargeChange = 2D;
rgSliderDays.ScrollBehavior = C1.Win.Input.RangeSliderScrollBehavior.ThumbStep;
rgSliderDays.SmallChange = 1D;
rgSliderDays.UpperValue = 30D;
//assign value to rangslider's min and max label
lblMin.Text = rgSliderDays.Minimum.ToString();
lblMax.Text = rgSliderDays.Maximum.ToString();Populate the purpose, country, and profession fields, and configure image selection.
Set the ItemsDataSource property of cmbPurpose to populate the list of travel purposes.
//add items to purpose combobox
cmbPurpose.ItemsDataSource = resource.GetString("Purposes").Split(",");
cmbPurpose.PostValidation.AllowDbNull = false;Create a country list and use it to populate splitBtnCountry.
namespace CountryCity
{
[Serializable]
public class Country
{
public Country() { }
public Country(string name, City[] cities)
{
Name = name;
Cities.AddRange(cities);
}
private List<City> _cities;
private City[] _cityArray;
public string Name { get; set; }
public string ISO2Name { get; set; }
public string ISO3Name { get; set; }
public City[] CityArray
{
get { return Cities.ToArray(); }
set
{
_cityArray = value;
if (_cityArray != null)
{
Cities.Clear();
foreach (City city in _cityArray)
{
city.Country = this;
Cities.Add(city);
}
}
}
}
[XmlIgnore]
public List<City> Cities
{
get
{
if (_cities is null)
{
_cities = new List<City>();
}
return _cities;
}
set
{
_cities = value;
foreach (City city in _cities)
{
city.Country = this;
}
}
}
public static List<Country> GetCountries()
{
XmlSerializer xs = new XmlSerializer(typeof(List<Country>));
XmlReader xr = XmlReader.Create("CountryCityConfig.xml");
return (List<Country>)xs.Deserialize(xr);
}
}
public class City
{
public City() { }
public City(string name)
{
CityName = name;
}
public string CityName { get; set; }
[XmlIgnore]
public Country Country { get; set; }
}
}Create an ImageList and add the images displayed with the SplitButton items.
//Get the data to bind to country combobox
Countries = Country.GetCountries();
imgList = new ImageList();
//create imagelist
for (int i = 0; i < Countries.Count; i++)
{
Country c = Countries[i];
Image img = (Image)resource.GetObject(c.ISO2Name);
if (img is null) continue;
imgList.Images.Add(c.Name, img);
}
string[] offices = Resources.Offices.Split(',');
foreach (string item in offices)
{
SplitButtonItem sbtn = new SplitButtonItem();
sbtn.Text = item;
sbtn.Click += Sbtn_Click;
splitBtnCountry.Items.Add(sbtn);
splitBtnCountry.TextAlign = ContentAlignment.MiddleLeft;
}Configure btnSelectPic to open a file-selection dialog when selected. Display the selected image in picBoxMain.
private void btnSelectPic_Click(object sender, EventArgs e)
{
OpenFileDialog fileDialog = new OpenFileDialog();
fileDialog.Filter = "Image files (*.jpg, *.jpeg, *.jpe, *.jfif, *.png) | *.jpg; *.jpeg; *.jpe; *.jfif; *.png";
if (fileDialog.ShowDialog() == DialogResult.OK)
{
picBoxMain.Image = Image.FromFile(fileDialog.FileName);
}
}Configure the drop‑down using the Control property of C1DropDownControl to host the DataGridView.
dataGridView.ColumnHeadersVisible = false;
dataGridView.RowHeadersVisible = false;
dataGridView.DataSource = _profession;Configure the DropDownControl using the Control property of C1DropDownControl class to host the DataGridView control on the drop-down form.
dropdownControl.Control = dataGridView;
dropdownControl.DroppedDown = false;Handle the SelectionChanged event of DataGridView and assign the DropDownControl.Text property to the Value of the current cell.
private void dataGridView_SelectionChanged(object sender, EventArgs e)
{
dropdownControl.Text = dataGridView.CurrentCell.Value.ToString();
}Run the project to view the travel registration form.
Note: WinForms .NET 5 Edition does not include rich design-time support yet. We will enhance it in future releases.
