WinForms DataGridView - databind to an object with a list property (variable number of columns)

由 夙愿已清 提交于 2020-01-18 22:40:50
问题 I have a .NET class I'd like to show in a DataGridView, and the default databinding - setting the DGV's DataSource to the object - produces 90% of my requirements (i.e. it's outputting the public properties correctly and I can add sorting easily). However, one of the properties I need to bind is a List which contains data which needs to be in separate columns after the other databound items. I'm stuck on how best to implement this. My class looks something like this: public class BookDetails

问题 I have a DataGridViewRow that I add to a DataGridView "table" programatically. I want one of the cells to be a DataGridViewButtonCell so I can click on it. (I realize I can have a handler on the datagridview for on_click but I'd like to keep this way for simplicity of code). I want to be able to set the forecolor/backcolor of a DataGridViewButtonCell. DataGridViewRow dgvRow = new DataGridViewRow(); dgvRow = (DataGridViewRow)dgv.Rows[0].Clone(); dgvRow.Cells[0].Value = filename; dgvRow.Cells[0

Why can't I bind a list of custom objects to datagridview?

问题 I have looked through your questions as well as elsewhere on the internet for the past two hours and cannot find a solution for my problem anywhere, or at least I didn't understand it if I did.
