GridView编辑删除操作

阅读更多关于 GridView编辑删除操作

第一种：使用DataSource数据源中自带的编辑删除方法，这样的不经常使用，在这里就不加说明了。另外一种：使用GridView的三种事件：GridView1_RowEditing（编辑）、GridView1_RowUpdating（更新）、GridView1_RowCancelingEdit（取消编辑）。 GridView1属性中将DataKeyNames的值设置为主键名，否则找不到索引，这个非常重要哦。该方法有2种操作，一种是不正确绑定列转换为模板列，第二种是转换为模板列。这里先说不转换为模板列的情况；首先;先对GridView进行数据绑定，无论用代码绑定还是DataSource绑定都能够。绑定好后，对GridView加入绑定列和编辑列（注意这里，加入好后不做不论什么修改，千万不要将它们转换为模板列），加入好后，将所要绑定的数据库表字段填入属性中。然后，分别激活上述提到的三种事件，然后加入代码： protected void GridView1_RowDeleting (object sender, GridViewDeleteEventArgs e) { //运行删除 string str = "delete from tb_hby where id='"+GridView1.DataKeys[e.RowIndex].Value.ToString()+"

阅读更多关于 How do I calculate the required height of a GridView that is inside of a ScrollView on Android?

问题 I have a GridView inside of a LinearLayout inside of a ScrollView that pages in data from the server. Beneath the GridView is a button to load more data. My GridView will have an ultimate height that is larger than the screen. If I set the height of my GridView to either wrap_content or parent_fill, it sizes itself to the exact available on-screen height and does not scroll at all, cropping out the extra rows. If I explicitly set the layout_height to something large, like 1000dip, scrolling
