Question

How to create a border above the grid(named as Holder) for wp7? What i tried is, when i create the grid to full screen and after i created the border on the top of the screen but when i debug it, the border is not visible. Can anyone help me with this? Thanks in advance for your hard work!

<Grid x:Name="BrowserHost" GotFocus="BrowserHost_GotFocus" Grid.RowSpan="2">

<StackPanel x:Name="Stack" Background="Transparent">
        <Border x:Name="Border" Background="{StaticResource PhoneAccentBrush}">
            <TextBox x:Name="UrlTextBox" KeyDown="UrlTextBox_KeyDown" Background="White" Margin="0,0,98,0">
        </Border>
</StackPanel>

MainPage xaml.cs

public partial class MainPage : PhoneApplicationPage
{
    private const int NumTabs = 4;

    private int currentIndex;
    private string[] urls = new string[NumTabs];
    private WebBrowser[] browsers = new WebBrowser[NumTabs];

    public MainPage()
    {
        InitializeComponent();
        ShowTab(0);
    }

    private void ShowTab(int index)
    {
        this.currentIndex = index;
        UrlTextBox.Text = this.urls[this.currentIndex] ?? "";
        if (this.browsers[this.currentIndex] == null) 
        {
            WebBrowser browser = new WebBrowser();
            this.browsers[this.currentIndex] = browser;
            BrowserHost.Children.Add(browser);
        }
        for (int i = 0; i < NumTabs; i++) 
        {
            if (this.browsers[i] != null) 
            {
            this.browsers[i].Visibility = i == this.currentIndex ? Visibility.Visible : Visibility.Collapsed;
        }
    }
}

private void UrlTextBox_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Enter) 
    {
        Uri url;
        if (Uri.TryCreate(UrlTextBox.Text, UriKind.Absolute, out url)) 
        {
            this.urls[this.currentIndex] = UrlTextBox.Text;
            this.browsers[this.currentIndex].Navigate(url);
        }
        else
            MessageBox.Show("Invalid url");
    }
}

But after i debug, neither the border nor UrlTextBox is visible.

Image:

I used the GotFocus event for the BrowserHost grid. That means, when i touched the grid(BrowserHost), the UrlTextBox and the border should be collapsed(I got this thing). And what i need is the BrowserHost should attain the full screen after the Border and UrlTextBox is collapsed. But for me it is not happening. Please see the below image. I want to make the BrowserHost in full screen when the user touches on the BrowserHost. I want the empty space to be filled with BrowserHost.

You need to specify BorderBrush and BorderThickness properties for the Border, like this

<Border Background="LightBlue" 
    BorderBrush="Green" 
    BorderThickness="2" >

Update:
Also Set Grid.Row=”0″ to your stackpanel.

And then modify your cs code

WebBrowser browser = new WebBrowser();
browser.Height = 400;
Grid.SetRow(browser, 1);
BrowserHost.Children.Add(browser);
