To get Node from row 10:
[c#]NodeBase node = flyGrid.Rows.GetNodeFromRow(10);
or (if flyGrid has plain (list, not hierarchical) structure) or has hidden nodes:
[c#]NodeBase node = flyGrid.Rows.Items[10];
To get column at index 5:
[c#]Column col = flyGrid.Columns.Items[5];
or (if flyGrid has unvisible columns):
[c#]Column col = flyGrid.Columns.VisibleColumns[5];
To get value from certain node at index 5:
[c#]
NodeBase node = flyGrid.Rows.GetNodeFromRow(10);
return node[5];
or (if need to get value relate to certain Column, especially in cases when column can be unvisible):
[c#]
Column col = flyGrid.Columns.Items[5];
NodeBase node = flyGrid.Rows.GetNodeFromRow(10);
return node[col];
