问题 I have a menu-activity, in which I have several positioned buttons. It fits my phone screen perfectly when in portrait mode, but in landscape mode it's destroyed.

问题 I have setup a DataGrid with a number of columns and a checkbox and column at the end of the row. I am also changing the layout of the datagrid on the OnItemCreated event which changes the layout of the datagrid by expanding the rows with the "Rowspan" attribute and remove the extra columns and controls where they are no longer required. The original datagrid layout was setup like this: ___________________________________________ | 1 | Employee Name | 01/08/10 |[] |[SAVE]| | 1 | Employee Name

问题 I want to make an application where whenever I touch the screen, which should be blank at the start, a button will be created and pop up onto the screen. So what I tried here is to make a button in main.xml and call it by id.

That works fine, too, but I'd like to disable that button after the user clicked it so he/she can't click it multiple times before the PostBack succeeds, so here's what I did in Page_Load : btnSubmit

问题 My buttons seem stretched, especially in landscape orientation. I can't find a property to adjust either on the UITabBar, UITabBarViewController, or on the UITabBarItem's themselves. (Of course, one answer would be to get an iPad...but that doesn't solve the need for a phone.)
