Hello,

You can use FR.Net in WPF:

using (Report report = new Report())
{
report.Load(...);
report.RegisterData(your_dataset);
report.Show();
}

Focusing problem ?

Hello everybody.
I have a Textbox and a Rectangle in my WPF window.
I want when a user click on the Rectangle this method runs and the Textbox gets the Focus :

void rect_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    Rectangle senderRectangle = sender as Rectangle;
    string name = Regex.Replace(senderRectangle.Name, @"Rect", "", RegexOptions.IgnoreCase) + "TextBox";
    TextBox destinationTextBox = this.FindName(name) as TextBox;
    destinationTextBox.Focus();
    destinationTextBox.SelectAll();
    destinationTextBox.Visibility = Visibility.Visible;
}

void textBox_LostFocus(object sender, RoutedEventArgs e)
{
	MessageBox.Show("LostFocus" );
}

But whenever the Textbox gets the Focus , it Loses the focus immediately and shows LostFocus message .

What's wrong with it ?
Thank you.

First, I would set the Visibility property on the TextBox BEFORE
calling Focus().

Second, make sure the Focusable and IsEnabled properties on the TextBox
are set to true.

You may want (or need) to make sure the Focusable property is set to false on
the Rectangle as well.

Thank you Mark .
I've done it, but my problem didn't solve .
This is the XAML code that I've used.

<Rectangle x:Name="hour01Rect" MouseLeftButtonDown="rect_MouseLeftButtonDown" 
	Fill="#FFF5F5F5" Stroke="#FF99AABD" HorizontalAlignment="Stretch" 
    Margin="0,0,30,0" Focusable="False" />
<TextBox FlowDirection="RightToLeft" Language="fa-ir" Text="نمونه" 
	FontSize="12" Margin="20,15,50,15"  Visibility="Hidden" 
    x:Name="hour01TextBox" LostFocus="textBox_LostFocus" 
    GotFocus="hour01TextBox_GotFocus" />

Your Rectangle has no size so I'm not sure how you're able to click on it.

I gave the Recangle a size...

<Rectangle x:Name="hour01Rect" Fill="#FFF5F5F5" Stroke="#FF99AABD" HorizontalAlignment="Stretch" Margin="0,0,30,0" Focusable="False" Height="23" Width="162" MouseLeftButtonDown="rect_MouseLeftButtonDown" />
<TextBox FlowDirection="RightToLeft" Language="fa-ir" Text="نمونه" FontSize="12" Margin="20,15,50,15"  Visibility="Hidden" x:Name="hour01TextBox" GotFocus="hour01TextBox_GotFocus" LostFocus="textBox_LostFocus" />

and simplified your code behind

private void hour01TextBox_GotFocus(object sender, RoutedEventArgs e)
{
}

private void textBox_LostFocus(object sender, RoutedEventArgs e)
{
    MessageBox.Show("LostFocus");
}

private void rect_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    <code>//Rectangle senderRectangle = sender as Rectangle;
    //string name = Regex.Replace(senderRectangle.Name, @"Rect", "", RegexOptions.IgnoreCase) + "TextBox";
    //TextBox destinationTextBox = this.FindName(name) as TextBox;</code>
    <code>hour01TextBox</code>.Visibility = Visibility.Visible;
    <code>hour01TextBox</code>.Focus();
    <code>hour01TextBox</code>.SelectAll();
}

...and it works fine for me.

For that, see this project http://www.mediafire.com/file/yzw2y2d20tz/WpfApplication1.rar[^]

At last my problem solved .
I've used this XAML code before textbox:

<ScrollViewer Grid.Row="1" Margin="10,0,10,10" >

we must use below XAML instead of above XAML :

<ScrollViewer Grid.Row="1" Margin="10,0,10,10"<code> Focusable="False"></code>

Thanks anyway Mark .

WPF save button

Hello,

I have two questions, the first is, I have a button that says "crop image" and I want it to change to "cancel" when the user clicks on "crop image" and vis versa, how can this be done, its easy in C# but WPF.... ??

second, the save dialog, its a little different than opendialog, i heard not much, the problem is, I have the code below, I want to save the image object which is the second object from my form, i have 2 image objects, one is the primary, the second is the crop image, I want to save the crop image, which we we call this object cropimage. anyways i want to save it but for some reason, i know I am missing something, again I have the code below, it will not save the crop image to a file extension jpg or bmp, what am i missing, here is the code below, thanks in advance:

private void _btnSave_Click(object sender, RoutedEventArgs e)
{
try
{
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = "Image1"; // Default file name
dlg.DefaultExt = ".jpg"; // Default file extensions
dlg.DefaultExt = ".bmp"; // Default file extensions
dlg.Filter = "Picture File (*.jpg)|*.jpg|*.bmp)|*.bmp"; // Filter files by extension

// Show save file dialog box
Nullable<bool> result = dlg.ShowDialog();

// Process save file dialog box results
if (result == true)
{
string selectedFileName = dlg.FileName;
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.UriSource = new Uri(selectedFileName);
bitmap.EndInit();
_imageCrop.Source = bitmap;

}
}
catch (Exception)
{
System.Windows.MessageBox.Show("Please save it to the appropriate file type.");
}

You're already writing your WPF code in C#, aren't you? Smile | :)

Just one of the many possibly ways...

In the click handler you could simply change the button's Content
(assuming the button Content is a String):

private void cropbutton_Click(object sender, RoutedEventArgs e)
{
  ...
    Button btn = sender as Button;
    if (cropmode == true}
    {
        btn.Content = "Cancel";
        cropmode = false;
    }
    else
    {
        btn.Content = "Crop Image";
        cropmode = true;
    }
  ...
}

There's some sample code for encoding to JPEG here: JpegBitmapEncoder Class[^]

What do you have so far that's not working? The link shows how to use the
encoders to save bitmap images.

Hello Mark,

I am looking at the link right now, under bitmap encoder method it shows me the code on how to encode an bitmap image:

[SecurityPermissionAttribute(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.UnmanagedCode)]
[SecurityPermissionAttribute(SecurityAction.InheritanceDemand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public virtual void Save(
Stream stream
)

but is there anything else I need to do? or am I looking in the wrong example?

I am looking at this link as my example, what do you think?

http://msdn.microsoft.com/en-us/library/aa969773.aspx[^]

and also I am looking at this too what do you think of this?

http://msdn.microsoft.com/en-us/library/system.windows.forms.savefiledialog.aspx[^]

just trying to figure out how to get the file to save my cropped image. thanks

I don't know about the sample code in the second link, but I imagine the stream
created there will work as well.

If you use the sample dialog code in your first link to get the pathname of the file to
save, you should be able to use that pathname in the code at this link:

JpegBitmapEncoder Class[^]

Scroll down to "This example demonstrates how to encode a BitmapSource
into a JPEG image using a JpegBitmapEncoder.".
