Adding rows on datagridview manually

Question

I've inserted a checkbox column and textbox column on the datagridview. how can add rows manually on the textbox column.

It should be like this:

checkbox | textbox
............................
checkbox | item1
checkbox | item2
checkbox | item3
checkbox | item4

Here is the code for checkbox and textbox on datagridview

public void loadgrid()
{
    DataGridViewCheckBoxColumn checkboxColumn = new DataGridViewCheckBoxColumn();
    CheckBox chk = new CheckBox();
    checkboxColumn.Width = 25;
    dataGridView1.Columns.Add(checkboxColumn);

    DataGridViewTextBoxColumn textboxcolumn = new DataGridViewTextBoxColumn();
    TextBox txt = new TextBox();
    textboxcolumn.Width = 150;
    dataGridView1.Columns.Add(textboxcolumn);     
}

Answer 1

You can use the Rows collection to manually populate a DataGridView control instead of binding it to a data source.

this.dataGridView1.Rows.Add("five", "six", "seven", "eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");

Take a look at the documentation

And you can do something like this too:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);
