Error when setting datasource

[Chris Thompson]

I get the error "no value at index -1" when I set the datasource to a dataset with no rows int it at run time.

If I set the datasource at design time and the dataset has no rows I get no error.

What gives? How do I get around this?

I don''t see a dropping a GridDataBoundGrid on a Form and using this formload to populate it with a datatable with no rows using 2.1.0.9.

private void Form1_Load(object sender, System.EventArgs e)
{
	DataTable dt = new DataTable("MyTable");
	int nCols = 4;
	for(int i = 0; i < nCols; i++)
	this.gridDataBoundGrid1.EnableAddNew = false;
	this.gridDataBoundGrid1.DataSource = dt;
}

Now if you are trying to reset data into an existing grid, then you may want to try calling:

grid.CurrentCell.EndEdit();
grid.Binder.EndEdit();

You can also try this code to make sure there is no currentcell when you reset the data.

grid.CurrentCell.MoveTo(-1, -1);
grid.Binder.CurrentPosition = -1;

If you can post a sample showing the problem, we can try to suggest something.
