VB.NET Datagrid

Question

我应该如何动态地在selectedindexedchanged上添加datagrid列？

Answer 1

I assume the Combobox contains datagrid-columns (or Datatable columns) ?

You can simply set the Visible property to false, when you have found the column.

In WinForms:

 Dim x as Integer = ...
 dataGridView1.Columns[x].Visible = False

But please take a look at your question, it contains virtually no useful information.

Answer 2

In side the selection change event paste this coding

Datagridview1.columncount += 1
