RadGrid Content(data) not appearing during runtime.

[Sang]

Hi,

I have used RadControls for WPF, and created a RadWindow and a RadGrid view, and entered some sample data into the RadGrid as per the following code:

<telerik:RadWindow
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        x:Class="WpfApplication6.MainWindow"
        HorizontalAlignment="Stretch" 
        VerticalAlignment="Stretch">
            <telerik:RadWindow.Resources>
                <XmlDataProvider x:Key="GridEntries" XPath="/Categories/Details">
                <x:XData>
                    <Categories>
                        <Details>
                            <Source>ABC</Source>
                            <Title>DEF</Title>
                            <Date>12/11/10</Date>
                            <Location></Location>
                            <Type></Type>
                            <Category></Category>
                            <Severity></Severity>
                            <ScenarioActivated></ScenarioActivated>
                            <Videowall></Videowall>
                        </Details>
                        <Details>
                            <Source>DEF</Source>
                            <Title>XYZ</Title>
                            <Date>22/05/10</Date>
                            <Location></Location>
                            <Type></Type>
                            <Category></Category>
                            <Severity></Severity>
                            <ScenarioActivated></ScenarioActivated>
                            <Videowall></Videowall>
                        </Details>
                        <Details>
                            <Source>PQR</Source>
                            <Title>XYZ</Title>
                            <Date>30/09/10</Date>
                            <Location></Location>
                            <Type></Type>
                            <Category></Category>
                            <Severity></Severity>
                            <ScenarioActivated></ScenarioActivated>
                            <Videowall></Videowall>
                        </Details>
                    </Categories>
            </x:XData>
        </XmlDataProvider>
    </telerik:RadWindow.Resources>
    <telerik:RadGridView 
        HorizontalAlignment="Center" 
        VerticalAlignment="Center" 
        Height="200" Width="876" AutoGenerateColumns="True"
        ItemsSource="{Binding Source={StaticResource GridEntries}}"/>
    </telerik:RadWindow>
The code is functioning fine during design time and the sample data i have written in the RadGrid is appearing during design time. but, when i run this XAML in Expression Blend, the RadWindow and radgrid appears, with no fields and no sample data in it. Just an empty Radgrid with no data appears in a radWindow. Please help me solve this problem i am facing. Thanx.

Hi Sang,

 
Looking at your code snippet I noticed that you did not specified an xmlns attribute that should be set to an empty string, as shown:

<Categories xmlns="">
                        <Details>
                            <Source>ABC</Source>
                            <Title>DEF</Title>
                            <Date>12/11/10</Date>
                            <Location></Location>
                            <Type></Type>
                            <Category></Category>
                            <Severity></Severity>
                            <ScenarioActivated></ScenarioActivated>
                            <Videowall></Videowall>
                        </Details>

 

And you will be able to see the data in RadGridView at runtime mantaining the same way you are setting its ItemsSource. You should do that if you want t be able to apply queries to a data island that is inline within the XAML file. 

All the best,
