View 14 RepliesI have a DataGridView bound to a binding source. I have also, however, added an unbound column in which I plan on putting numbers calculated from the bound columns. The problem is, Any time I edit my unbound column (on any row), the value doesn't stay. If I programmatically edit the values, they never show up. If I type in the cell, then upon hitting enter or clicking outside of the cell, whatever I typed disappears.

This is provided within the LOAD event of the SecondaryForm.When SecondaryForm.Load events finishes, the program goes back to MainForm right after the line "SecondaryForm.Show" and here the values of the column SUM disappear.When i write those values runtime, they never disappear.
View 6 RepliesAt runtime, I have a collection of rows (Row class). Each of them consist of column values, represented by instances of a ColumnValue class. The name of the columns are determined at runtime, and are in a separate columns descriptor collection (Column class).I want to create a DataGridView that displays all Row instances. Of course, the DataGridView's columns shall be exactly those specified by the Column instances in the containing collection.But since DataGridView's columns can fetch their values from a list item's public properties only, and I cannot easily define such a property at runtime, I cannot use DataGridView to display the tabular data.
