The button event handler for XAML page not firing for Textbox field, but it
fires for the date selected value for calendar. I have listed code file code
file below. Any suggestions will be appreciated.

<UserControl

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>
<ColumnDefinition Width="75" />
<ColumnDefinition Width="325" />

</Grid.ColumnDefinitions>


<TextBlock x:Name="name1" Text="Name:" Grid.Row="0"
Grid.Column="0"></TextBlock>

<TextBlock Text="Date:" Grid.Row="1" Grid.Column="0"></TextBlock>
<TextBlock x:Name="message1" Text="Message:" Grid.Row="2"
Grid.Column="0" Grid.ColumnSpan="2"></TextBlock>
<TextBox Text="Your Name" Width="150" HorizontalAlignment="Left"
Grid.Row="0" Grid.Column="1"></TextBox>
<StackPanel Grid.Column="1" Grid.Row="1" Orientation="Vertical" >
<basics:Calendar SelectionMode="SingleDate"

<Button Click="okButton_Click" x:Name="okButton" Width="75"
Height="25" HorizontalAlignment="Left" Content="OK" ></Button>
</StackPanel>

</Grid>
</UserControl>

Also below is my code behind for the page.XAML.cs flle.

using System.Net;

using System.Windows.Controls;
using System.Windows.Documents;

namespace HelloSilverLight
{
public partial class Page : UserControl
{
public Page()
{
InitializeComponent();
}

private void okButton_Click(object sender, RoutedEventArgs e)
{
string dateString;
if (cal1.SelectedDate == null)
{
dateString = "<date not selected>";
}
else
{
dateString = cal1.SelectedDate.ToString();
}
string s = message1.Text = "Hi " + name1.Text + "\n" +
"Selected Date: " + dateString;

}

private void Button_Click(object sender, RoutedEventArgs e)
{

}
}
}

Hi Alex,

Is my understanding correct that you want to output below after clicking
the ok button?

Hi [user input in the TextBox goes here]
Selected Date: [user selected date goes here]

The problem is whatever you input in the TextBox, it always shows:

Hi Name:
Selected Date: [user selected date goes here]

Right? If so the problem is you're referring to the TextBlock instead of
the TextBox in the code behind. Please try this:

xaml:

<TextBox x:Name="TextBox1" Text="Your Name" Width="150"
HorizontalAlignment="Left"
Grid.Row="0" Grid.Column="1"></TextBox>

xaml.cs
private void okButton_Click(object sender, RoutedEventArgs e)
{
string dateString;
if (cal1.SelectedDate == null)
{
dateString = "<date not selected>";
}
else
{
dateString = cal1.SelectedDate.ToString();
}
string s = message1.Text = "Hi " + TextBox1.Text + "\n" +
"Selected Date: " + dateString;

}

In xaml give the TextBox a name and refer to it in code behind by its name.

If my understanding is wrong please clarify the problem.

Allen,

Thanks for the code suggestion. I have implemented them in my project but
still not getting the right output. I am sending a zipped file to your in box
for you to take a look at.

Hi Alex,


Thanks for your project. You're adding a new TextBox whose name is
TextBox1. However the original TextBox still exists there and it's the
TextBox whose Text is changed by you. The new TextBox1 is not shown on the
screen therefore you cannot change it's Text.

Please remove the following TextBox from the xaml to make it work:

<TextBox Text="Your Name" Width="150" HorizontalAlignment="Left"
Grid.Row="0" Grid.Column="1"></TextBox>

Allen,

It works now. I see what I am doing wrong. I was confused on what a TextBox
and TextBlock elements are. I caould not have done it without you. Thanks a
lot. I am starting to get up to speed on Databinding and have realized I need
to get comfortable with WCF. Could you point me to some good links on these
topics
