DataBinding with XamNumericEditor not working
posted

Hy all.

I have a sample where I use databinding between a XamDataGrid and XamNumericEditor, but I think I miss something because it's not working.

In the xaml file I have a simple XamDataGrid with some fields and I fill the grid in the code behind:

<my:XamDataGrid Name="xamDataGrid1" GroupByAreaLocation="None" Theme="Office2k7Blue" Style="{StaticResource GridWithButtons}">

<my:XamDataGrid.FieldLayouts>

<my:FieldLayout>

<my:FieldLayout.Fields>

<my:Field Name="Title" Label="{Binding Path=headerTitle, Source={StaticResource resStaticData}, Mode=OneWay}" />

<my:Field Name="Running" Label="{Binding Path=headerRunning, Source={StaticResource resStaticData}, Mode=OneWay}"/>

<my:Field Name="MPAA" Label="{Binding Path=headerMPAA, Source={StaticResource resStaticData}, Mode=OneWay}"/>

<my:Field Name="Critics" Label="{Binding Path=headerCritics, Source={StaticResource resStaticData}, Mode=OneWay}"/>

<my:Field Name="Valid" Label="{Binding Path=headerValid, Source={StaticResource resStaticData}, Mode=OneWay}"/>

<my:Field Name="Load" Label="Load"/>

<my:Field Name="Date" Label="Date"

DataType="{x:Type sys:DateTime}"

Converter="{x:Static local:DateTimeConverter.Instance}">

<my:Field.Settings>

<my:FieldSettings EditAsType="{x:Type sys:String}"/>

</my:Field.Settings>

</my:Field>

</my:FieldLayout.Fields>

</my:FieldLayout>

</my:XamDataGrid.FieldLayouts>

</my:XamDataGrid>

private void Window_Loaded(object sender, RoutedEventArgs e)

{

DataTable t = GenerateData().Tables[0];

xamDataGrid1.DataSource = t.DefaultView;

}

public DataSet GenerateData()

{

DataSet ds = new DataSet();

DataTable dt = ds.Tables.Add("TopMovies");

dt.Columns.Add("Selected", typeof(bool));

dt.Columns.Add("Title", typeof(string));

dt.Columns.Add("Running", typeof(string));

dt.Columns.Add("MPAA", typeof(string));

dt.Columns.Add("Critics", typeof(string));

dt.Columns.Add("Valid", typeof(bool));

dt.Columns.Add("Load", typeof(float));

dt.Columns.Add("Date", typeof(DateTime));

dt.Rows.Add(new object[ { false, "Open Season", "1 hr. 40 min.", "PG", "C", true, 4.7, DateTime.Now });

dt.Rows.Add(new object[ { false, "Gridiron Gang", "120 min.", "PG-13", "C+", true, 7.2, DateTime.Now });

dt.Rows.Add(new object[ { false, "The Illusionist", "1 hr. 49 min.", "PG-13", "B", false, 78.3, DateTime.Now });

dt.Rows.Add(new object[ { false, "Pirates of the Caribbean: Dead Man's Chest", "145 min.", "PG-13", "B-", true, 78, DateTime.Now });

dt.Rows.Add(new object[ { false, "Open Season", "1 hr. 40 min.", "PG", "C", true, 34, DateTime.Now });

dt.Rows.Add(new object[ { false, "Gridiron Gang", "120 min.", "PG-13", "C+", true, 676, DateTime.Now });

dt.Rows.Add(new object[ { true, "The Illusionist", "1 hr. 49 min.", "PG-13", "B", false, 46, DateTime.Now });

dt.Rows.Add(new object[ { false, "Pirates of the Caribbean: Dead Man's Chest", "145 min.", "PG-13", "B-", true, 345, DateTime.Now });

dt.Rows.Add(new object[ { false, "Open Season", "1 hr. 40 min.", "PG", "C", true, 23, DateTime.Now });

dt.Rows.Add(new object[ { false, "Gridiron Gang", "120 min.", "PG-13", "C+", true, 53, DateTime.Now });

dt.Rows.Add(new object[ { true, "The Illusionist", "1 hr. 49 min.", "PG-13", "B", false, 67, DateTime.Now });

return ds;

}

I have a XamNumericEditor and I bound the Value propetry to the Load property of the items of the grid. But when I change the value in the XamNumericEditor, the value from the grid is not changed. Here is the XamNumericEditor.

<igEditors:XamNumericEditor Value="{Binding Path=Load, Mode=TwoWay}"/>

Thanks very much for any idea.

    Hy again.

    I found the problem. For the XamNumericEditor I was using a format like this: double:{0}.{1} but the type of the field Load was float and it didn't see it.

    Thanks very much any way.
