主题：关于ListView的显示问题

改成

Dim ggs = dt.GetValues("规格", "款号 = '" & dm.Text & "'and 合同号 like '%" & cj.Text & "%'","_sortkey desc")

不对，这样会变成“XS,XL,L,M,S,”,我需要的是XXS,XS,S,M,L,XL,XXL,....等等自己去设定的

那你改成

 

Dim ggs = {"XXS","XS","S","M","L","XL","XXL"}

改一下

 

Dim ggs() As String = {"XXS","XS","S","M","L","XL","XXL"}

  连没有数据的都显示出来了

具体实例发上来测试。
