Commands in datatemplate

[Dom]

Hi,

I have a list of tabs (binding on a collection)
in each tab I have a control with a command.
Problem is command doesn't seem to work, it never launches.

Here's a simple examble that works :


       <telerik:RadTabControl >
                                <telerik:RadTabItem Header="Test">
                                    <Button Content="Test" Command="{Binding CharacteristicMenu}" CommandParameter="Add" />
                                </telerik:RadTabItem>
                            </telerik:RadTabControl>

and here's one close to what I want to do that doesn't work :

  <telerik:RadTabControl ItemsSource="{Binding Tabs}">
                                <telerik:RadTabControl.ItemTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Path=Name.Text, Mode=TwoWay}" />
                                        </StackPanel>
                                    </DataTemplate>
                                </telerik:RadTabControl.ItemTemplate>
                                <telerik:RadTabControl.ContentTemplate>
                                    <DataTemplate>
                                        <Grid>
                                            <StackPanel>
                                                <Button Content="Test" Command="{Binding CharacteristicMenu}" CommandParameter="Add" />
                                            </StackPanel>
                                        </Grid>
                                    </DataTemplate>
                                </telerik:RadTabControl.ContentTemplate>
    </telerik:RadTabControl>

I can't seem to make the commands works inside a datatemplate. I need to get commands to work with a button and with your contextuelmenu.
Is it a limitation of the tabcontrol or something? I tried a radbutton instead of button with no success (which wouldn't of fixed the problem with a contextuelmenu anyway).

Thanks
Dom

Hi Dom,

I wasn't able to reproduce this issue on our side. It might be related to the structure of your view models and the business data. I prepared a sample project - please have a look at it and let me know if it works for you or if I'm missing something.

Tried your project, seems to be what I want, i added the docking around it, and it still works.

I compared yours to mine, and problem seems to be that I put the command/Delegate in the mainviewmodel (didn't have a view model for each tabs, just had the data for each to bind).

It seems to be the problem so I'll try changing that.
