HI

My problem is to show in a column of my ListView of pictures after conversion ConvertImage (byteBLOBData); I also think that problem comes can be of my source code XAML.
If you can look at my code please

private void RemplirListeUtilisateur()
{
dt_ListeUtilisateur.Clear();
cmd.CommandText = "SELECT U.IDUTILISATEUR,U.MyImage, U.NOMUTILISATEUR,U.PRENOMUTILISATEUR,U.ADRESSE,U.CODEPOSTALE,U.TELEPHONE,P.NOMPAYS AS PAYS,D.NOMDEPARTEMENT AS DEPARTEMENT FROM UTILISATEUR U INNER JOIN PAYS P ON U.IDPAYS = P.IDPAYS INNER JOIN DEPARTEMENT D ON U.IDDPEPARTEMENT = D.IDDEPARTEMENT";
sqlDa = new SqlDataAdapter();
sqlDa.SelectCommand = cmd;

try
{
sqlDa.Fill(dt_ListeUtilisateur);
DataTable Temp = new DataTable();

Temp.Columns.Add("IDUTILISATEUR");
Temp.Columns.Add("NOMUTILISATEUR");
Temp.Columns.Add("PRENOMUTILISATEUR");
Temp.Columns.Add("ADRESSE");
Temp.Columns.Add("CODEPOSTALE");
Temp.Columns.Add("TELEPHONE");
Temp.Columns.Add("PAYS");
Temp.Columns.Add("DEPARTEMENT");
Temp.Columns.Add("MyIMAGE");

for (int Index = 0; Index < dt_ListeUtilisateur.Rows.Count; Index++)
{
DataRow MyDataRow = Temp.NewRow();

MyDataRow["IDUTILISATEUR"] = dt_ListeUtilisateur.Rows[Index] ["IDUTILISATEUR"].ToString();
MyDataRow["NOMUTILISATEUR"] = dt_ListeUtilisateur.Rows[Index]["NOMUTILISATEUR"].ToString();
MyDataRow["PRENOMUTILISATEUR"] = dt_ListeUtilisateur.Rows[Index]["PRENOMUTILISATEUR"].ToString();
MyDataRow["ADRESSE"] = dt_ListeUtilisateur.Rows[Index]["ADRESSE"].ToString();
MyDataRow["CODEPOSTALE"] = dt_ListeUtilisateur.Rows[Index]["CODEPOSTALE"].ToString();
MyDataRow["TELEPHONE"] = dt_ListeUtilisateur.Rows[Index]["TELEPHONE"].ToString();
MyDataRow["PAYS"] = dt_ListeUtilisateur.Rows[Index]["PAYS"].ToString();
MyDataRow["DEPARTEMENT"] = dt_ListeUtilisateur.Rows[Index]["DEPARTEMENT"].ToString();
int c = dt_ListeUtilisateur.Rows.Count;
if ((dt_ListeUtilisateur.Rows[Index]["MyImage"].ToString() != String.Empty) || (dt_ListeUtilisateur.Rows[Index]["MyImage"].ToString().Equals("null")))
{
Byte[] byteBLOBData = new Byte[0];
byteBLOBData = (Byte[])(dt_ListeUtilisateur.Rows[c - 1]["MyImage"]);
MemoryStream stmBLOBData = new MemoryStream(byteBLOBData);
ConvertImage(byteBLOBData);
MyDataRow["MyImage"] = images;

}

Temp.Rows.Add(MyDataRow);
}

lstUtilisateur.ItemsSource = Temp.DefaultView;

Code XAML :
<gridviewcolumn header="Image" displaymemberbinding="{Binding Path=MyImage}">

How to access silverlight control properties from aspx page

Hi,

I am building a silverlight control for uploading files. that has some user defined properties like file filter etc.
I want to assign values to those from the aspx page in which i am hosting that control.
Please tell me how to do that.

Thanks in advance..

You can use param tags or the InitParameters property in the page that hosts the silver light control.

Take a look at the code of the html or aspx page that gets created as part of your silver light project.

This link gives a few details on how to use InitParameters.

Thanks for the reply.

I want to know if i can use the ID of the control to directly access the properties.
example: if the the silverlight control Id is Xaml1 and one of the property is FolderName

can i use Xaml1.FolderName="value"?

Another thing i want to know how the control is getting called.
Please let me know if i can access the properties without using query string or InitParameters.

Thanks in advance.

WPF RichTextBox - Appending Colored text

Harvey Saayman4-May-09 22:08

Hey guys

I need to append text to a WPF RichTextBox, but specific colors.

After much googling i put together the following method

private void AppendRtfText(string Text, Brush Color)
{
    TextRange range = new TextRange(txtChat.Document.ContentEnd, txtChat.Document.ContentEnd);
    range.Text = Text;
    range.ApplyPropertyValue(TextElement.ForegroundProperty, Color);
}

Now this works just fine, but I need to be able to specify RGB values.

The TextElement.ForegroundProperty only accepts a Brush and as far as I can see I cant specify RGB for a brush like i would with the Color class.

Any ideas? Cause I'm running out

Hi..
I am new to this concept.How to add a message or text in the ellipse of xmal element at run time of windows application.Is in a xmal ellipse control we can put text box to write text? if yes how, if not please suggest me the other way if possible...
the code :
Ellipse x:Name="C2" Height="353" Width="440" Stroke="LightPink" StrokeThickness="05" Visibility="Hidden" Fill="blue" Canvas.Top="63" Canvas.Left="80">

You're looking at the problem from the wrong end: An ellipse does not have the opportunity to display text, but a Label can take whatever look you want through a control template Smile | :)

<Grid>  
  
  <Grid.Resources>
  
    <Style x:Key="EllipseLabel" TargetType="{x:Type Label}">
    
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="{x:Type Label}">
            <Grid >
              <Ellipse  Width="{TemplateBinding Width}"
                        Height="{TemplateBinding Height}"
                        Stroke="LightPink"
                        StrokeThickness="05"
                        Fill="blue" />
              <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
            </Grid>
          </ControlTemplate>
        </Setter.Value>
      </Setter>
    
    </Style>   
  </Grid.Resources>

  
    <Label Width="200" Height="100" Style="{StaticResource EllipseLabel}" Content="hello world" />
  
</Grid>

...accordingly, if you change your label's content, the text changes.

There's no problem doing that - you can change a label's content at runtime through a binding expression or code. It's a label, after all. even though it looks like an ellipse.

This is regular WPF 101 - just give the label in my sample a name like this:

...and in code, set the text:

myLabel.Content = "this is easy";

If you want to enter text, you need to style another control, e.g. textbox:

<Grid>  
  
  <Grid.Resources>
  
    <Style x:Key="EllipseLabel" TargetType="{x:Type TextBox}">
    
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="{x:Type TextBox}">
            <Grid >
              <Ellipse  Width="{TemplateBinding Width}"
                        Height="{TemplateBinding Height}"
                        Stroke="LightPink"
                        StrokeThickness="05"
                        Fill="blue" />
              <ScrollViewer HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0" x:Name="PART_ContentHost"/>
            </Grid>
          </ControlTemplate>
        </Setter.Value>
      </Setter>
    
    </Style>   
  </Grid.Resources>

  
    <TextBox Width="200" Height="100" Style="{StaticResource EllipseLabel}" Text="hello world" />
  
</Grid>

UserControl Databinding

mikla5213-May-09 3:14

3-May-09 3:14

I give up, can't find any good information about this anywhere Frown | :(

I have a UserControl with 6 textboxes. I have a quite complex datastructure from where I want to fill these textboxes. The datastructure contains several sets of "String[6]" but I can't figure out how to bind it Frown | :(

public partial class MyAttBox : UserControl
{
        // 6 of these with different names
        public static DependencyProperty LowChRXProperty = DependencyProperty.Register("LowChRX", typeof(String), typeof(MyAttBox));
        public String LowChRX
        {
            get { return (String)GetValue(LowChRXProperty); }
            set { SetValue(LowChRXProperty, value); }
        }
}

"main" XAML:

<AttBox:MyAttBox Header="GSM 850" x:Name="AttBox_GSM850" />

my data is stored like:

public class ABC
    {
        private Dictionary<String, List<String>> m_values = new Dictionary<String, List<String>>();

        public Dictionary<String, List<String>> Values
        {
            get { return m_values; }
            set { m_values = value; }
        }

What I want to is to select a Key in my code and connect the Values to the texboxes in my UC. How?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
