Question

In a WP7.5 application, i have a listbox containing a grid.
This grid contain two row, and two columns (2×2)

In grid, i display textbox, my problem is thar the alignement is bad ! I don’t know why, i set horizontalAligement=true, but no change !

Here is my code :

<ListBox x:Name="ListBoxTiers"  HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0">
<ListBox.ItemTemplate>
    <DataTemplate>

        <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" VerticalAlignment="Top" >
            <Grid Margin="20" VerticalAlignment="Top" HorizontalAlignment="Left">
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition />
                </Grid.RowDefinitions>

                <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <TextBlock  HorizontalAlignment="Left" TextWrapping="Wrap" Grid.Row="0" Grid.Column="0" Margin="0,0,10,0" x:Name="TxtBox_cCodeTiers" Text="{Binding m_strCode}" FontWeight="Bold" FontSize="22" />
                <TextBlock  HorizontalAlignment="Left" TextWrapping="Wrap" Grid.Row="0" Grid.Column="1" Margin="0,0,10,0" x:Name="TxtBox_cNomTiers" Text="{Binding m_strNom}"   FontWeight="Bold" FontSize="22" />
                <TextBlock  HorizontalAlignment="Left" TextWrapping="Wrap" Grid.Row="1" Grid.ColumnSpan="2" Grid.Column="0" Margin="0,0,10,0" x:Name="TxtBox_cCPostal" Text="{Binding m_strFonction}" />                                   
            </Grid>

        </StackPanel>

    </DataTemplate>
</ListBox.ItemTemplate>

Here is my result :

Here is my Class :

public class CTiers
{
    public enum TypeTiers { Client, Fournisseur, Contact, Collaborateur, Commercial, Prospect};

    TypeTiers m_TypeTiers { set; get; }

    public string m_strTypeTiers { get; set; }
    public string m_strCode    { set; get; }
    public string m_strNom { set; get; }
    public string m_strPrenom { set; get; }
    public string m_strTel { set; get; }
    public string m_strGsm { set; get; }
    public string m_strFax { set; get; }
    public string m_strMail { set; get; }
    public string m_strWebSite { set; get; }
    public string m_strVille { set; get; }
    public string m_strCpostal { set; get; }
    public string m_strRue { set; get; }
    public string m_strFonction { set; get; }

    public CTiers()
    {

    }

    public CTiers(TypeTiers oTypeTiers, string strCode, string strNom, string strPrenom, string strTel, string strGsm, string strFax, string strRue,string strVille,string strCPostal,string strMail,string strWebSite,string strFonction)
    {
        m_TypeTiers = oTypeTiers;
        m_strCode = strCode.Trim();
        m_strNom = strNom.Trim();
        m_strPrenom = strPrenom.Trim();
        m_strVille = strVille.Trim();
        m_strTel = strTel.Trim();
        m_strGsm = strGsm.Trim();
        m_strFax = strFax.Trim();
        m_strWebSite = strWebSite.Trim();
        m_strRue = strRue.Trim();
        m_strMail = strMail.Trim();
        m_strCpostal = strCPostal.Trim();
        m_strTypeTiers = oTypeTiers.ToString().Trim();
        m_strFonction = strFonction.Trim();
    }

}

Anyone could help me please ?

Thanks a lot 🙂

Answer 1

Your code is ok, problem is with the text trimming only.

I used the same xaml in your question and did a sample.

Case 1: First I took all the strings trimmed

List<Myclass> list = new List<Myclass>();
list.Add(new Myclass() { m_strCode = "001", m_strNom = "sample1", m_strFonction = "Fonction1" });
list.Add(new Myclass() { m_strCode = "002", m_strNom = "sample2", m_strFonction = "Fonction2" });
list.Add(new Myclass() { m_strCode = "003", m_strNom = "sample3 ", m_strFonction = "Fonction3" });
list.Add(new Myclass() { m_strCode = "004", m_strNom = "sample4", m_strFonction = "Fonction4" });
list.Add(new Myclass() { m_strCode = "005", m_strNom = "sample5", m_strFonction = "Fonction5" });
ListBoxTiers.ItemsSource = list;

And the result is : (Formated clearly as you expect)

Case 2: In this case, I took some strings with extraa spaces (observe sample1 and 004)

List<Myclass> list = new List<Myclass>();
list.Add(new Myclass() { m_strCode = "001", m_strNom = "    sample1", m_strFonction = "Fonction1" });
list.Add(new Myclass() { m_strCode = "002", m_strNom = "sample2", m_strFonction = "Fonction2" });
list.Add(new Myclass() { m_strCode = "003", m_strNom = "sample3 ", m_strFonction = "Fonction3" });
list.Add(new Myclass() { m_strCode = "004    ", m_strNom = "sample4", m_strFonction = "Fonction4" });
list.Add(new Myclass() { m_strCode = "005", m_strNom = "sample5", m_strFonction = "Fonction5" });
ListBoxTiers.ItemsSource = list;

And now the result is :

Hence, the problem is you are not properly trimming the text. Take care about that.

Update:

There you go. You don’t always call the constructor for instantiating the object. So, the better way is this.

    private string _m_strFonction;
    private string _m_strNom;
    private string _m_strCode;

    public string m_strCode
    {
        get { return _m_strCode; }
        set { _m_strCode = value.Trim(); }
    }
    public string m_strNom
    {
        get { return _m_strNom; }
        set { _m_strNom = value.Trim(); }
    }
    public string m_strFonction 
    { 
        get { return _m_strFonction; }
        set { _m_strFonction = value.Trim(); }
    }
