显示页眉/页脚时的GridView是空VB.net [英] Show Header/Footer when Gridview is Blank VB.net

问题描述

我知道有一个解决方案，但我在努力得到它转换为正确VB：（

I realise there is a solution for this but I am struggling to get it to convert to VB correctly :(

我已经得到了一个级联组具有根据每个人的数据结果，我真的很高兴，下拉菜单的。

I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.

不过由于回发电网将消失，直到选择了第二个值，看起来可怕

However due to the post back the grid will disappear until the second value is selected and looks awful

反正是有内VB，让头部留下来，如果有网格视图中没有数据？

Is there anyway within VB to allow the header to stick around if there is no data within the grid view?

提前非常感谢。
