如何将数据从列表插入到数据网格视图的列

Question

I have a data grid view (dataGridViewPorosity) with 2 columns and I want to insert data from a list (Porosity) to one of this columns, but the exception is: Index was out of range. most be non-negative and less than the size of the collection.

here is my code:

        var source = new BindingSource
        {
        DataSource = Porosity
        };
        for (int i = 0; i < source.Count; i++)
        {
             dataGridViewPorosity[1,i].Value = source[i];
        }

I saw the similar questions but cannot fix the problem

Answer 1

The DataGridView control works differently from the other tables you might know (or arrays). You need to choose the row and cell. The cell is basically the column.

dataGridViewPorosity.Rows[rowNumber].Cells[cellNumber].Value = source[i];

I assume you want to use the second cell and the row with the i value. You can do it just like that:

dataGridViewPorosity.Rows[i].Cells[1].Value = source[i];

Good luck!

Try to create new rows, like so:

int rownum = dataGridViewPorosity.Rows.Add();

And then use the rownum as the row number you would like to insert your data to.

dataGridViewPorosity.Rows[rownum].Cells[1].Value = source[i];

Of course, these must be in the for loop.
