How to copy DataGridView contents to Dataset? - ado.net

Question

i'm not good with ADO.NET
so used the following code that i got from Internet
but i get the error "There is no row at position 0." # the marked line(*)
even though i can see a value is being passed using breakpoints
DataSet ds = new DataSet();
DataTable dt = new DataTable("ProdFromDGV");
ds.Tables.Add(dt);
foreach (DataGridViewColumn col in dataGridView1.Columns)
{
dt.Columns.Add(col.HeaderText, typeof(string));
}
foreach (DataGridViewRow row in dataGridView1.Rows)
{
foreach (DataGridViewCell cell in row.Cells)
{
*dt.Rows[row.Index][cell.ColumnIndex] = cell.Value.ToString();*
}
}
dt.WriteXml("table.xml");

Answer 1

You need to first create a DataRow type and add it into your DataTable before you can start assigning to it.
So your code will now be something like:
DataSet ds = new DataSet();
DataTable dt = new DataTable("ProdFromDGV");
ds.Tables.Add(dt);
foreach (DataGridViewColumn col in dataGridView1.Columns)
{
dt.Columns.Add(col.HeaderText, typeof(string));
}
foreach (DataGridViewRow row in dataGridView1.Rows)
{
foreach (DataGridViewCell cell in row.Cells)
{
// This will not work, but it's something similar to this that you need here...
DataRow row = new DataRow();
dt.RowCollecion.Add(row);
// Now you can assign to the row....
dt.Rows[row.Index][cell.ColumnIndex] = cell.Value.ToString();
}
}
dt.WriteXml("table.xml");
Hope this helps some..

// This will not work, but it's something similar to this that you need here...
Just change
DataRow row = new DataRow();
to:
DataRow row = dt.NewRow();
and it will work.
