I have button on the Grid that does not detects PreviewMouseLeftDown click event.
After some testing I figured that the problem is in <Grid PreviewMouseMove="onMouseMove" >

If I remove PreviewMouseMove="onMouseMove" part, then MouseDown event is detected, but i need that line of code, since I also have to detect mouse position inside that grid only.

XAML:

<Grid PreviewMouseMove="onMouseMove" Background="Transparent">

    <ItemsControl Name="btnTableImageList">

        <ItemsControl.ItemTemplate>

            <DataTemplate>

                <Button Content="{Binding Content}"

                        Height="{Binding Height}"

                        Width="{Binding Width}"

                        Tag="{Binding Tag}"

                        Margin="{Binding Margin}"

                        Background="{Binding Background}" 

                        HorizontalAlignment="Center"

                        PreviewMouseLeftButtonDown ="tblButton_MouseDown"

                        PreviewMouseLeftButtonUp ="tblButton_MouseUp"

                        Click="ClickHandlerTableBtn"

                        TextBlock.TextAlignment="Center" />

            </DataTemplate>

        </ItemsControl.ItemTemplate>

    </ItemsControl>

</Grid>

Any idea is welcomed. Thanks!

I totally agree with themightylc, but also understand you... WPF and MVVM are not so "easy" to get used to, I do it for a year more or less, and still have a lot to learn.
In that kind of situation I only could advise you to read some tutorials about WPF, DataBinding and ObservableCollection and ViewModel (these are the keywords you need to know).
1) Create a ViewModel where you can define a ObservableCollection, ObservableCollection is kind of list, but using it you can update your View (almost) automaticaly.so when you launch your application, you will read the list of buttons you need to display, then add them to the ObservableCollection

for your tests will be something like that :

Button button1=new Button();

Button button2=new Button();



//define all dimensions/parameters of your button



MyObservableCollection.Add(button1);

MyObservableCollection.Add(button2);

Then in XAML you just need to specify the ItemsSource of ItemsControls(MyObservableCollection). doing like that you don't need anymore all description of buttons inside.

Then when you click to add a button(in your case), you just need to make in code behind something like

Button newButton=new Button(); 

newButton.Height=defaultHeight...//width, background etc...

MyObservableCollection.Add(newButton);

again, just for advise if WPF/MVVM is new to you, I would advise to begin with easier samples, make a small listview with simple objects inside, or a listbox.

Could also advise you these websites :
wpf-tutorial.com
www.wpftutorial.net

At the end this is actually working properly.

For test I have set up a label, and in MouseMove event i am sending Mouse Position to that label,lblCoord.Content = Mouse.GetPosition(Application.Current.MainWindow);

In case of MouseClick I am sending lblCoord.Content="MouseClick";

And in case of MouseDown I am sending lblCoord.Content="MouseDown";.

I can see mouse coordinates in lblCoord, I can see MouseClick, but it never displayed MouseDown.

However, if i call MessageBox inside MouseDown event, everything works. So i guess that XAML <Grid> PreviewMouseMove="onMouseMove" works even when I am not moving mouse so it is sending coords to a Label all the time and overwrites lblCoord.Content="MouseDown"; faster than I am able to see it.

The answer to this question is: Don't work with WPF and expect WinForms results...
Thanks to everybody for their time and effort!
