I have a datagridview that gets populated with some data from an excel file.
I want to be able to populate a textbox with the cell that I have currently selected when I click the button.
I have tried the following but have been unsuccessful in finding a way to do this.

private void btnGetValue_Click(object sender, EventArgs e)
       {

           txtField1.Text = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
       }

What I have tried:

txtField1.Text = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();

If you are only working with single selection make sure that you set the mode on the DataGridView:

C#

dataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect;

Now, you can work with the SelectedCells property of the dataGridView control:

C#

private void btnGetValue_Click(object sender, System.EventArgs e)
{
    var selectedcell = dataGridView1.SelectedCells?.Count == 1
                           ? dataGridView1.SelectedCells[0]
                           : null;

    if (selectedcell != null)
    {
        // do something with the selected cell...
    }
}
