Question

How to add a row in datagridview in winform application.

Scenario is:

• I’ve one grid on windows form.
• Grid’s columns are pre-definded. (Here, I mean column index, name ,
  header text and order is not changeable at runtime.)
• I need to add new row in that grid.

Anyone, help me in this regard. How can I do this task ?

Answer 1

Just try like this –

dataGridView1.Rows.Add(<col1 value>,<col2 value>,...)

The parameters will be values you intended for your each columns.

EDIT :

Taking your code from other comments, you can simply use it like this-

myMainApplication.dgvBooksDetails.Rows.Add(objBook.ID, objBook.Title, objBook.Author, 
            objBook.Genre, objBook.Price, objBook.PublishDate, objBook.Description);

EDIT

In Sub Form, store instance of Main Form –

public MainForm _mainForm;

In Main Form :

SubForm frm = new SubForm();
frm.MainForm = this;
frm.Show();

Then to fill up datagrid, do like this –

_mainForm.dgvBookDetails.Rows.Add(.....

Hope it helps!
