WPF-Creating controls dynamically in WPF

Couple of days I wrote about creating ASP.Net controls dynamically in C#, following code explain how to create in WPF (using c#).



using System;

using System.Collections.Generic;

using System.Data;

using System.Linq;

using System.Text;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Controls.Primitives;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Media.Animation;

using System.Windows.Navigation;

using System.Windows.Shapes;
namespace CompleWebCRF.Test
{

/// <summary>

/// Interaction logic for dynamicControl.xaml

/// </summary>

public partial class dynamicControl : Page

{
public dynamicControl()
{

InitializeComponent();



test();

}




private void test()
{
int iRow=0;int iCol = 0;
myGrid.RowDefinitions.Clear();
createLabel("Text Box", iRow, iCol);
CreateTextBox(iRow, iCol+1);



iRow++;
createLabel("List Box", iRow, iCol);
CreateListBox(iRow, iCol+1);



iRow++;
createLabel("Combo Box", iRow, iCol);

CreateCheckBox(iRow, iCol+1);

iRow++;
createLabel("Radio Button", iRow, iCol);
CreateRadioButton(iRow, iCol+1);

CreateRadioButton(iRow, iCol+2);

iRow++;

CreateButton(iRow, iCol);
