This tip is the C# translate version of Master Detail Datagridview. Review the original article for further details.

Introduction

Many of us developers come across a problem on how to display Master-Detail views within a single Datagridview control like the third party applications Devexpress.

The native Windows Forms control datagridview doesn’t support Master-Detail views within a single control. By majority approach, this should be done through two separate datagridview controls.

In this tip, I will discuss with you my kind of approach on how to display Master-Detail data views inside a single datagridview control. Although an alternate Datagrid control supports master detail datagridview, expanding a child datagridview will occupy the whole control which will give you not a good layout datagridviews to your data as needed for data validation. The typical layout we need is what we could see in the attached screenshot.

Improvements

• The grids are populated with List<> objects.
• The grids are fully editable.
• The grids show a tooltip based on description attribute of every property of the class.
• Fixed an issue that prevents moving through the child grid with arrow keys.

Using the Code

In this sample demo, I used a single List<> collection of objects.

Follow these very simple steps:

1. Declare a variable referenced to MasterControl:

   MasterGridView masterGridView1
   

2. Load data:

   private void Form1_Load(object sender, EventArgs e)
   {            
         masterGridView1.DataSource = Persona.getPersonas();
   }

3. Set child TabControl on the same hierarchy than parent datagridview:

   masterGridView1.SetChildTabcontrol();

            masterGridView1.SetChildTabcontrol();
        }

        private void Form1_Load(object sender, EventArgs e)
        {            
            masterGridView1.DataSource = Persona.getPersonas();

        }
