Get DataKey values in GridView RowCommand

由 不想你离开。 提交于 2019-12-17 08:29:12
问题 I have a GridView with an associated DataKey , which is the item ID. How do I retrieve that value inside the RowCommand event? This seems to work, but I don't like the cast to LinkButton (what if some other command is firing the event?), and I'm not too confident about the NamingContainer bit. LinkButton lb = (LinkButton)e.CommandSource; GridViewRow gvr = (GridViewRow)lb.NamingContainer; int id = (int)grid.DataKeys[gvr.RowIndex].Value; I'm aware that I could instead pass that ID as the

I'm new to MVC, and am not following how you'd do paging and sorting on a grid. I'm used to using the asp.Net GridView control with an ObjectDataSource pointed at objects in our business layer - and in that case the ODS handles all of the paging & sorting using the methods that our ORM generates on

GridView编辑删除操作

由 雨燕双飞 提交于 2019-12-17 05:15:36
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()+"

Making GridView items square

问题 I would like the items of my GridView to be square. There are 2 columns and the items width is fill_parent (e.g. they take as much horizontal space as possible. The items are custom views. How do I make the items height to be equal to their variable width? 回答1: There is a simpler solution when GridView columns are stretched. Just override the onMeasure of the GridView item layout with... @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure
