Question

I have a datagridview where I select a selection of cells, then order them ready for processing.

var q = Dat.SelectedCells.OfType<DataGridViewCell>()
       .OrderBy(x => x.RowIndex);//order selectedCells by row-index

var p = q.OfType<DataGridViewCell>().OrderBy(x => x.ColumnIndex);

var p is now a list of IOrderedEnumerable filled with datagridviewCells.

My question is: How can i get the first and last DataGridViewColumn out of p?

Answer 1

You can extract the index of the first and last columns from the initial cells collection:

var firstColumnIndex = q.Min(c => c.ColumnIndex);
var lastColumnIndex = q.Max(c => c.ColumnIndex);
