This quick start will guide you through the steps of creating a simple travel registration form using the Input controls. Follow the steps below to get started.

Set Up the Application

1. Create a new Windows Forms App (.NET).
2. In Visual Studio, go to Project > {ProjectName} Properties and select .NET 5.0 in Target Framework combobox.
3. Install the nuget package of C1.Win.Input.
   Observe: In design view, observe that Input controls are added to the toolbox.

Add and Configure Input Controls

In this step, we are adding and configuring various Input controls to make you familiar with each one of them.

1. In design view, drag and drop label controls, radio buttons and rest of the input controls as required.
2. Place them on the form to create the desired layout.
   
   
3. Set the Name and Text property of each control as shown in the table below.

   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

4. Set the Font property of lblTitle to Georgia, 18pt, Bold.
5. Set the Value property of numEditTraveller to 1.
6. Configure rgSliderDays as shown in the code below.

   C#

   コードのコピー

   //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 Data

1. Set the ItemsDataSource property of cmbPurpose combobox.

   C#	コードのコピー
   //add items to purpose combobox cmbPurpose.ItemsDataSource = resource.GetString("Purposes").Split(","); cmbPurpose.PostValidation.AllowDbNull = false;

2. Create a Country list to populate data in splitBtnCountry splitbutton.
3. Create an ImageList and add images to it to render them in the SplitButton items list.

   C#

   コードのコピー

   //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; }

4. Configure the btnSelectPic to open a file dialog for selecting a file on button click.

   C#	コードのコピー
   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); } }

5. Set the visibility to DataGridView to false in the Properties window. The DataGridView is required to assign data to the Control property of the DropDownControl. Assign a DataSource to the DataGridView control, which populates the grid to add the same data to the dropdown form.
   

   C#	コードのコピー
   dataGridView.ColumnHeadersVisible = false; dataGridView.RowHeadersVisible = false; dataGridView.DataSource = _profession;

6. Configure the DropDownControl using the Control property of C1DropDownControl class to host the DataGridView control on the drop-down form.
   

   C#	コードのコピー
   dropdownControl.Control = dataGridView; dropdownControl.DroppedDown = false;

7. Invoke the event handler of the SelectionChanged event of the DataGridView control. Assign the Text property of the DropDownControl to Value property of the current cell in the DataGridView control.
   

   C#	コードのコピー
   private void dataGridView_SelectionChanged(object sender, EventArgs e) { dropdownControl.Text = dataGridView.CurrentCell.Value.ToString(); }

8. Run the project to see the travel registration form.
