The icons are stored in the res/drawable folder, are 629X629 and average about 5 KB in size.

GridView with CheckBox – Select All and Highlight Selected Row

阅读更多关于 GridView with CheckBox – Select All and Highlight Selected Row

Introduction To enable row selection in GridView, we can either include a Button control or CheckBox control. For example, selecting a row item to delete. Using CheckBox control will give a better user experience than a Button control and it is user friendly when we require multiple row selections.

阅读更多关于 AsyncFileUpload postback causes double upload

问题 I implemented the AsyncFileUpload control on a web page. This web page requires uploaded files to appear in a GridView .

GridView with horizontal scroll

问题 I currently have a GridView scrolling vertically, and everything works fine. But now that I want to change my layout and have the gridview grow on its width instead of height as it grows bigger I am lost. I have tried to simply change the column width each time an item is added to the gridview. But no vertical scroll appears, even though the items are added correctly.
