Switching Datasources
posted

Hi,

on application startup a xamDataGrid is bound to static resource:

<Grid.Resources>
    <XmlDataProvider x:Key="Data" XPath="/Ntn">
        <x:XData>
            <Ntn xmlns="">
                <Note GridHeaderSA="SA" GridHeaderKA="KA" GridHeaderEx="Ex" GridHeaderM="M" />
            </Ntn>
        </x:XData>
    </XmlDataProvider>
</Grid.Resources>

This xmlDataProvider is bound as datasource:

<igDP:XamDataGrid DataSource="{Binding Source={StaticResource Data},XPath=Ntn}" />

At runtime data is gathered and loaded into an ObservableCollection and this collection is bound to the xamDataGrid:

Me.gridNtn.DataSource = myDataCollection

Now would like to create the following behaviour:

If data is loaded correctly, i would like to view this in the grid. If loading fails, the grid should "fallback" to the static resource. But how to do this in Code?

In short terms: is it possible to bind a xamDataGrid to static resource in code?

thanks in advance

    Hello Stephan,

     

    Thank you for your post. I have been looking into it and I suggest you use the following code in order to bind the XamDataGrid to the static resource:

    XmlDataProvider data = grid1.Resources["Data"] as XmlDataProvider;
Binding b = new Binding();
b.Source = data;
b.XPath = "Note";
xamDataGrid1.SetBinding(XamDataGrid.DataSourceProperty,b);

     

    Where grid1 is the name of the Grid where you define the XmlDataProvider and the xamDataGrid1 is the name of the XamDataGrid.Please let me know if this helps you or you need further clarifications on this matter.

     

    Looking forward for your reply.
