C# - Why does the program hang and crash when adding a new row to the DataGridView?

Question

.NET

I read XML and enter the read data into the DataGridView, after I count the first Node and enter it into the control line, the line should be executed this.dataGridView1.Rows.Add();
. But at this moment the program freezes and crashes after a few seconds.

Answer 1

Well, without seeing the code, it’s impossible to say for sure, try using the debugger

Answer 2

Using try-catch got an exception: "Rows cannot be programmatically added to the DataGridView's collection of rows if the control is data bound." So I understand when data is entered there, it is impossible to add a new line. But I tried to put the addition of a line at the very beginning of the Form_Load method, and the program still crashes at this place. Maybe I'm somehow adding lines incorrectly? Or is it necessary to initialize the type of each cell?
