I'm a bid fed up with WPF databounding and is trying out the non-databound road :)

Probably me thats doing something wrong, But I get this error:
"Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead."

I modified your FirstLook example by adding this method to the codebehind:
        private void LB() 
        { 
            System.Data.DataTable dv = ExamplesDB.GetCustomers(); 
 
            foreach (System.Data.DataRow dr in dv.Rows) 
            { 
                radGridViewFirstLook.Items.Add(dr); 
            } 
        } 

And removing the DataContext and ItemSource setters in the XAML file:
<QuickStart:ExampleControl x:Class="Telerik.Windows.Examples.GridView.FirstLook.Example" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:QuickStart="clr-namespace:Telerik.Windows.QuickStart;assembly=Telerik.Windows.QuickStart" 
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 
    xmlns:e="clr-namespace:Telerik.Windows.Examples"
    <Grid> 
        <telerik:RadGridView Name="radGridViewFirstLook" ColumnsWidthMode="Fill" AutoGenerateColumns="False" Margin="0,0,-1,0"
            <telerik:RadGridView.Columns> 
                <telerik:GridViewDataColumn Width="100" IsReadOnly="False" DataType="{x:Null}"  HeaderText="Customer ID" UniqueName="CustomerID" /> 
                <telerik:GridViewDataColumn Width="100" DataType="{x:Null}" HeaderText="Company Name" UniqueName="CompanyName" /> 
                <telerik:GridViewDataColumn Width="100" DataType="{x:Null}" HeaderText="Country" UniqueName="Country" /> 
                <telerik:GridViewDataColumn Width="100" IsReadOnly="False" DataType="{x:Null}" HeaderText="City"  UniqueName="City" /> 
                <telerik:GridViewDataColumn Width="100" DataType="{x:Null}" HeaderText="Contact Name"  UniqueName="ContactName" /> 
                <telerik:GridViewDataColumn Width="100" DataType="{x:Null}" HeaderText="Bool" UniqueName="Bool" /> 
            </telerik:RadGridView.Columns> 
        </telerik:RadGridView> 
        <telerik:RadPanelBar Height="6" Margin="232,0,284,-330" Name="radPanelBar1" VerticalAlignment="Bottom" /> 
    </Grid> 
</QuickStart:ExampleControl> 

Why isn't this working - I'm not using ItemsSource?

Hi Lars Berg,

You are not doing anything wrong but currently the RadGridView control does not support unbound mode and the only way to feed data into the grid is to use its ItemsSource property. That feature could not make it in the official release. Luckily we don't have much work left to implement the feature, and we will ship it with a future service pack release.

Kind regards,

Hello,

Does RadGridView now support unbound mode?

Hello Brian Matuska,

Unfortunately this mode is still unsupported. Is this feature a must-have for your scenario?

All the best,

With the Q1 2010 release will the grid support unbound data?  If not, do you still plan on adding this at a later date?

Hello David Cecil,

You can add items to the Items property of the grid. I have attached a sample project. I hope this helps.
