Hi I have the following data in datagridview in c# winforms:

---

 Column A | Column B | Column C | Group
---------------------------------------

```
 Register 1  |       10,00     |       15,00 | Group 1
 Register 2  |       10,00     |       15,00 | Group 1
 Register 3  |       10,00     |       15,00 | Group 2
 Register 4  |       10,00     |       15,00 | Group 2

```

I want to get this in the following form:

---

 Column A | Column B | Column C
-------------------------------

**Group 1**  

 Register 1 | 10,00 | 15,00  

 Register 2 | 10,00 | 15,00  

**Group 1**  

 Register 3 | 10,00 | 15,00  

 Register 4 | 10,00 | 15,00

I dont want to use multiple datagridviews
