I have utilized a TableControl and it works fine.

 

<editing:TableControl AutomationProperties.AutomationId="_tableControl" x:Name="tableControl" 
     Grid.Row="1" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" 
     SelectedRowsChanged="tableControl_SelectedRowsChanged"
     TableContent="{Binding Path=TableContent}" 
     RowContextMenu="{StaticResource MyRowContextMenu}"
     SelectedRowContextMenu="{StaticResource MyRowContextMenu}">
</editing:TableControl>

 

Is there way to detect user left mouse click on a row in the table? I tried PreviewMouseLeftButton but that event is valid for whole table not specifically for a row.

I will make the developer of this control aware of this issue.  However, there is a solution to get the selected row for a TableControl by using the ActiveRowIndex attribute of the TableControl.  In order to illustrate this i update this sample: Map-Exploration - TableControlsDockpane sample 

I updated the XAML in Map-Exploration\TableControlsDockpane\AttributeTable.xaml by adding the ActiveRowIndex attribute to my TableControl:

<TabControl.ContentTemplate>
 <DataTemplate>
  <editing:TableControl TableContent="{Binding TableContent}"
                        RowContextMenu="{Binding RowContextMenu}"
                        ActiveRowIndex="{Binding ActiveRowIdx, Mode=TwoWay}" 
                        SelectedRowContextMenu="{Binding RowContextMenu}" />
 </DataTemplate>
</TabControl.ContentTemplate>

And then i added the following code snippet to Map-Exploration\TableControlsDockpane\TabItemViewModel.cs:

private int _lastRowIdx = -1;
private int _ActiveRowIdx;
public int ActiveRowIdx
{
	get { return _ActiveRowIdx; }
	set
	{
		_ActiveRowIdx = value;
		NotifyPropertyChanged(nameof(ActiveRowIdx));
		var tableControl = VisualTreeRoot.GetChildOfType<TableControl>();
		if (tableControl != null)
		{
			var rowIdx = tableControl.ActiveRowIndex;
			if (rowIdx == _lastRowIdx) return;
			_lastRowIdx = rowIdx;
			System.Diagnostics.Debug.WriteLine($@"row: {rowIdx}");
			_ = GetObjectIdAsync(tableControl, rowIdx);
		}
	}
}

public async Task<long> GetObjectIdAsync (TableControl tableControl, int rowIdx)
{
	var oid = await tableControl.GetObjectIdAsync(rowIdx);
	ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show ($@"rowIdx:  {rowIdx} has OID: {oid}");
	return oid;
}

 The trick is to add "Mode=TwoWay" to the ActiveRowIndex attribute in XAML and that ActiveRowIndex is also set when the row is unselected.  Running the code is get this:

It would be nice if Esri added ItemContainerStyle to TableControl so something like this could be done.

My original idea was using DataGrid but I have about 50K rows. In my case, TableControl is better to handle that many rows in addition coming with some nice ESRI controls. However, I could not find any event such as  row click or mouse left  click on row. I don't know how to implement one either.

Thanks a lot for detailed explanation. I did not think about two way binding. Let me try it.
