How to add control to a Panel in WPF using VB.NET

Introduction
 
Here in this article I am explaining that how we can add controls to a panel. As we have used StackPanel. StackPanel arranges the content either vertically or horizontally. The by default setting of the StcakPanel is Vertical. StackPanel generally Stacks the element. Firstly we will add a StackPanel. In StackPanel we will add a TextBlock and a Tab control. When you clicked the Tab control, a Button control should be added to the StackPanel. The Implementation  needs a StackPanel, TextBlock, Tab control.



Getting Started

• Simply create a new WPF application.
• Drag a StackPanel, TextBlock and a Tab control on MainWindow. Your window will look like below.
  
  
  
  
• your MainWindow.xaml will look like below.
  
  <Window x:Class="MainWindow"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  Title="MainWindow" Height="290" Width="287">
  <StackPanel>
  <TextBlock Name="txt" FontSize="16">How to add control to a Panel</TextBlock>
  <TabControl>
  <TabItem MouseLeftButtonUp="AddButton">
  <TabItem.Header>Click for Add Control</TabItem.Header>
  </TabItem>
  </TabControl>
  <StackPanel Name="stackpan1"></StackPanel>
  </StackPanel>
  </Window>
  
• Then attach the below code in code behind file.
  
  Private addbtn As System.Windows.Controls.Button, addbtn1 As System.Windows.Controls.Button,
  addbtn2 As System.Windows.Controls.Button,addbtn3 As System.Windows.Controls.Button
  Private Sub btnAdd(sender As Object, e As MouseButtonEventArgs)
  stackpan1.Children.Clear()
  addbtn = New Button()
  addbtn.Content = "i have added a New Button"
  stackpan1.Children.Add(addbtn)
  End Sub
  
• Now run your application.
