gridview

问题 I'm working on replacing an existing web grid in an ASP.NET web application, with a new implementation. The existing grid is powerful, but not flexible enough. It also brings with it all kind of frameworks we don't like to have on our web pages. While looking into existing options I noticed I can break the available solutions into two main approaches. The older approach is represented best by the ASP.NET GridView. This is a classic ASP.NET control that generates the needed HTML on the server,

问题 In a activity i need two GridView each of them take as much as it needs as height. No gridview has separate scrollbar but they have only one scrollbar. I tried something like this. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <GridView android:id="@+id/gridView1" android:layout_width="fill_parent" android:layout_height="wrap_content" //as much height as it needs

问题 I have a List of complex objects containing other objects within that I give as the data source to a gridview.(currently I'm using BoundFields for the columns). I need to bind data to the columns from the objects within at run time. How can this be done? 回答1: Use a LINQ projection to flatten (denormalise) the entity graph. You can either create a new ViewModel type class, or alternatively bind to an anonymous class, something like this: var viewList = ( from entity in entityList select new {

问题 I have a GridView with a custom adapter that wont refresh. In the debugger I can see that getView is not being called after notifyDataSetChanged . I have no idea why... I can see that the underlying data is being changed but nothing is happening to the GridView. I tried several solutions which didn't work, so I'm posting what I think should be the right one (even though it clearly isn't...) This is in my main activity private GridView grid; private TileGridAdapter gridAdapter; private

问题 I'm building a GridView control which encapsulates a child gridview. The child gridview holds a div tag which is displayed when the user selects a row in the parent gridview. However, even though the contents is hidden i.e. the div tag, an extra column is added - how do I get rid of the extra column. In the tutorial it states that by adding a </td></td> and starting a new row <tr> this should happen but it does (I also noticed that the author turned off gridlines so my assumption is that he

问题 I have approximate 50000 row gridview.and i set the pagesize 20 grid view.so how we can find the last row gridview.If we do next then it takes more time. 回答1: If I get your question right, you want to shift to last page from first page. What you can do is when you are binding the gridview save number of rows in your data source in viewstate : viewstate["rowCount"]=number; Then use a seperate link for navigating to last page which fires pageindexchanging event. On that event you can calculate

问题 I am attempting to reorder a ListView in my UWP project. <ListView Grid.Row="1" Name="List" Margin="12, 0, 12, 0" ItemTemplate="{StaticResource ListDataTemplate}" SelectionMode="None" IsItemClickEnabled="True" ItemClick="List_ItemClick" AllowDrop="True" CanReorderItems="True" ReorderMode="Enabled" DropCompleted="List_DropCompleted" /> In Code behind: private void List_DropCompleted(UIElement sender,DropCompletedEventArgs args) { UseManualOrder = true; } The UI Works great.
