How to databind control in GridViewDataColumn Data Template

[Art Kedzierski]

I'm having an issue getting a RadProgressBar to databind in a DataTemplate of a GridViewData Column. Here is my code:

<telerik:RadGridView Name="radGridView1"
                     Canvas.Left="48"
                     Canvas.Top="48"
                     telerik:StyleManager.Theme="Transparent"
                     ShowGroupPanel="False"
                     AutoGenerateColumns="False"
                     ItemsSource="{Binding}"
                     IsFilteringAllowed="False"
                     CanUserSelect="False"
                     RowIndicatorVisibility="Collapsed"
                     RowStyle="{DynamicResource GridViewRowStyle1}"
                     HeaderRowStyle="{DynamicResource GridViewHeaderRowStyle1}">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn Width="300"
                                    DataMemberBinding="{Binding Path=TSE, Converter={StaticResource TSEconverter}}"
                                    Header="TSE"
                                    CellStyle="{StaticResource GridViewCellStyle1}"
                                    HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}" />
        <telerik:GridViewDataColumn Width="100"
                                    DataMemberBinding="{Binding Path=My_Count}"
                                    Header="Count"
                                    CellStyle="{StaticResource GridViewCellStyle1}"
                                    HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}"
                                    TextAlignment="Center"
                                    HeaderTextAlignment="Center" />
        <telerik:GridViewDataColumn Width="150"
                                    DataMemberBinding="{Binding Path=My_Percent_Double, Mode=OneWay}"
                                    Header="Status"
                                    CellStyle="{StaticResource GridViewCellStyle1}"
                                    HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}"
                                    TextAlignment="Center"
                                    HeaderTextAlignment="Center">
                <telerik:GridViewDataColumn.CellTemplate>
                    <DataTemplate>
                            <telerik:RadProgressBar Name="PercentBar"
                                                    Orientation="Horizontal"
                                                    Margin="0"
                                                    Height="24"
                                                    Style="{StaticResource statusBar}"
                                                    Value="{Binding Path=My_Percent_Double, Mode=OneWay}" />
                    </DataTemplate>
                </telerik:GridViewDataColumn.CellTemplate>
            </telerik:GridViewDataColumn>
        <telerik:GridViewDataColumn Width="100"
                                    DataMemberBinding="{Binding Path=My_Status}"
                                    Header="2pd"
                                    CellStyle="{StaticResource GridViewCellStyle1}"
                                    HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}"
                                    TextAlignment="Center"
                                    HeaderTextAlignment="Center" />
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

I can see the progress bar on project run, but no values are present (zero bars). What am I doing wrong?

Hi Art Kedzierski,

The proper way would be to create a custom column as demonstrated in this blog post.
