I'm doing it in a CheckedChanged event of a RadioButton in a TemplateField of
MyGridView

protected void MyRadioButton_CheckedChanged(object sender, EventArgs e)
{
TextBox.Text = MyGridView.SelectedRow.Cells[1].ToString();
}

It doesn't mater because even if I do this:
string MyString = MyGridView.SelectedRow.Cells[1].ToString();
it will give me the same error!!! and it looks like in the click event of
the RadioButton the "SelectedRow" is not set or equal to null !!!?

Hi,

You need to make sure that the SelectedIndex property is not set to -1
when you try to access the SelectedRow.

There has to be a command type control somewhere in your template (e.g.
button or LinkButton) that generates a postback event and is assigned
the string value "Select" to its CommandName property (a RadioButton
control can't be used for this). That will raise a SelectIndexChanged
event and the SelectedRow property will then point to an actual row of
the grid.
