"Item 3, column 1",
"Item 4, column 1",
"Item 5, column 1",
"Item 1, column 2",
"Item 2, column 2",
"Item 3, column 2"});
this.listBox1.Location = new System.Drawing.Point(0, 0);
this.listBox1.MultiColumn = true;
this.listBox1.Name = "listBox1";
this.listBox1.ScrollAlwaysVisible = true;
this.listBox1.Size = new System.Drawing.Size(120, 95);

Remarks
If you set the value to zero (0), a default width is assigned to each column. If the ListBox is a multicolumn ListBox, this property returns the current width of each column in the list. You can use this property to ensure that each column in a multicolumn ListBox can properly display its items.
