向datagridview添加新列

Question

我想在现有的datagridview中添加新列,以便:

DataColumn col = new DataColumn(( dataGridView1.ColumnCount+1).ToString());
dataGridView1.Columns.Add(col);

但它不起作用..如何做到这一点？

Answer 1

这很容易..

 dataGridView1.Columns.Add("Column","Test");

Answer 2

我认为您需要指定列将包含的单元格类型.

例如:

DataGridViewColumn  newCol = new DataGridViewColumn(); // add a column to the grid
DataGridViewCell cell = new DataGridViewCell(); //Specify which type of cell in this column
newCol.CellTemplate = cell;

newCol.HeaderText = "test2";
newCol.Name = "test2";
newCol.Visible = true;
newCol.Width = 40;

gridColors.Columns.Add(newCol);
