问题 I'm trying to implement Infinite Scrolling on a gridview to speed up my web application, since the gridview is being bound to a sql query that returns thousands of records at start (it's the client's wish, and I can't change that.) So I've been following the directions for adding Infinite Scrolling to a gridview found here, and it does work -- the first time the user scrolls to the bottom of the div. The second time, nothing. Here's the code I'm using to track the div's scroll event. The

问题 In reference to my question, How to get boundfield value, or am I totally wrong?

问题 I love Eclipse's hierarchy view which quickly shows all the subtypes and supertypes of my Java classes and interfaces. However, the results I am looking for are made confusing by the fact they also show all the types from my unit tests. While I find this helpful at time, I mostly find it annoying. Any way to filter this? 回答1: In the Hierarchy View, select the menu, and then choose "Select a Working Set". Create a new Working Set that includes everything except the Test classes. Use the new

问题 I'm using a GridView in Android. I need to register as many clicks as possible, but gridview reacts to clicks very slow, even if there is no acutal code to execute... is there a possibility to speed this up? 回答1: Depending on the application, you might want to code up a custom component. I had a similar problem and replaced the old gridview with a component based on TableLayout. It was more work, but was worth it in the end (faster and more flexible). Here's a handy article to get you started

问题 I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.

So for that's why grid is not binding. Here is my code $.ajax({ type: "POST", url: "schoolregistration.aspx/GetGridData", contentType: "application/json; charset=utf-8", datatype: "json", success:

问题 How do I define grid-lines for a GridView? Is there an attribute or do I have to draw my own background with them in it? 回答1: There is no such attribute. The easiest thing is to create a subclass of GridView and override dispatchDraw() or onDraw() to do it yourself. 回答2: set the background to the view(inflate layout) inside the GridView so that gridview display the line automatically. 回答3: You can just set a padding for each cell of the grid view so that that looks like the grid line. Each

问题 I have a list of product quantity and a grid view. The grid view is already bind to some data. But I wanted to display the list of product quantity at the third column of grid view. Here is the code behind on how I bind the data to grid view: gvProduct.DataSource = distSPUItem; gvProduct.DataBind(); BoundField column = new BoundField(); column = new BoundField(); column.HeaderText = "Unit Quantity"; for (int index = 0; index < productQuantityList.Count; index++) { column.DataField = index
