How to access Button programatically if the button is inside using C# - wpf

Question

I have few questions as I am usign XAML for the first time.
How do I use the button (BrowseButton) to browse a folder in Harddrive ?
In this case as the button is inside
Can I use the way I have shown below?
Actually first dockpanel will hold the image and some label and the other dockpanel will have tabcontrol in it.
If I have a tabcontrol, How can I add a listview which can increase the tabs during runtime.. and the listview should be available in the runtime also.
How to add a close("X") mark on the top of the tab to close the button
probably I asked a lot of questions, sorry :(
Please help

Answer 1

1) The browse code should be something like this:
private void BrowseButton_Click(object sender, RoutedEventArgs e)
{
System.Windows.Forms.FolderBrowserDialog browse = new System.Windows.Forms.FolderBrowserDialog();
browse.RootFolder= Environment.SpecialFolder.MyDocuments;
browse.SelectedPath = "C:\\InitalFolder\\SomeFolder";
if (browse.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
txtBxBrowseTB.Text = browse.SelectedPath;
}
}
2) I have tried to simplify the xaml. Does this look like something you could go with?:
<Grid>
<Image Name="imgClientPhoto" Margin="0" Height="262" VerticalAlignment="Top" HorizontalAlignment="Left" ></Image>
<StackPanel VerticalAlignment="Stretch" >
<StackPanel VerticalAlignment="Top" Orientation="Horizontal" Height="30">
<Button Name="BrowseButton" Content="Browse" Click="BrowseButton_Click" HorizontalAlignment="Right" Width="111" />
<Label Name="label1" Width="69.75" FontSize="13" VerticalContentAlignment="Center" HorizontalContentAlignment="Right">Path:</Label>
<TextBox Name="txtBxBrowseTB" Width="200" Text="TextBox" VerticalContentAlignment="Center" TextWrapping="Wrap" TextChanged="BrowseTB_TextChanged"></TextBox>
</StackPanel>
<StackPanel>
<StackPanel Orientation="Vertical">
<TextBox Height="50" Name="textBox1" />
<ListBox Height="470" Name="listBox1" Background="LightGray" Margin="0,0,0,0" BorderBrush="IndianRed" BorderThickness="3" MouseLeftButtonUp="listBox1_MouseLeftButtonUp">
<ListBoxItem>User1</ListBoxItem>
<ListBoxItem>User2</ListBoxItem>
<ListBoxItem>User3</ListBoxItem>
<ListBoxItem>User4</ListBoxItem>
</ListBox>
</StackPanel>
<TabControl Name="tabControl1" />
</StackPanel>
</StackPanel>
</Grid>
You can also have a close button in the tab item Header. As many of the content properties in xaml controls, the content can actually be controls, and not necessary just a text.
<TabControl Name="tabControl1" >
<TabItem Name="tabItem1" >
<TabItem.Header>
<StackPanel Orientation="Horizontal">
<Label>TabHeader1</Label>
<Button Height="20" Width="20" FontWeight="Bold" Click="CloseTabButton_Click">X</Button>
</StackPanel>
</TabItem.Header>
<Grid Height="144">
<ListView />
</Grid>
</TabItem>
</TabControl>
3) Here is how you would add the tabs in C# dynamically:
private void listBox1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
//Get selected item
ListBoxItem item = (ListBoxItem)listBox1.SelectedItem;
string itemText = item.Content.ToString();
//Check if item is already added
foreach (TabItem tItem in tabControl1.Items)
{
if ((string)tItem.Tag == itemText)
{
//Item already added, just activate the tab
tabControl1.SelectedItem = tItem;
return;
}
}
//Build new tab item
TabItem tabItem = new TabItem();
tabItem.Tag = itemText;
//First build the Header content
Label label = new Label();
Button button = new Button();
label.Content = itemText;
button.Content = "X";
button.Height = 20;
button.Width = 20;
button.FontWeight = FontWeights.Bold;
button.Click += CloseTabButton_Click; //Attach the event click method
button.Tag = tabItem; //Reference to the tab item to close in CloseTabButton_Click
StackPanel panel = new StackPanel();
panel.Orientation = Orientation.Horizontal;
panel.Children.Add(label);
panel.Children.Add(button);
tabItem.Header = panel;
//Then build the actual tab content
//If you need only the ListView in here, you don't need a grid
ListView listView = new ListView();
//TODO: Populate the listView with what you need
tabItem.Content = listView;
//Add the finished tabItem to your TabControl
tabControl1.Items.Add(tabItem);
tabControl1.SelectedItem = tabItem; //Activate the tab
}
private void CloseTabButton_Click(object sender, RoutedEventArgs e)
{
//The tab item was set to button.Tag when it was added
Button button = (Button)sender;
TabItem tabItem = (TabItem)button.Tag;
if (tabItem != null)
{
button.Click -= CloseTabButton_Click; //Detach event handler to prevent memory leak
tabControl1.Items.Remove(tabItem);
}
}
