Updating 事件都可以處理欄位檢查，在那個地方處理比較好呢？答案是由資料源頭的 Sql Data Source 控制項來處理會比較好，主要原因如下： 1.儘量不要在 UI 控制項處理資料驗證動作，因為一旦更換其他 UI 控制項(如更換其他廠商開發的 Grid View 控制項)，程式碼就又要改寫。 2.不同的 UI 控制項繫結 Sql Data Source 控制項，都可以適用相同方法。例如 Form View 及 Grid View 不同的 UI 控制項，都可以在 Sql Data Source. Update 方法去執行更新動作，不會引發 UI 控制項的相關事件，但是一樣會引發 Sql Data Source.
In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.
The Grid View does know the events that should be used to implement them, so the exceptions shown above are thrown when you try to perform one of these operations, but you have implemented the appropriate event handler.
The problem is, I’d very much like to do so, if ASP. But I can’t set a Data Source property or anything on the Sql Data Source!!! I probably have to read the cells on the Grid View of the selected row, find the controls, get the values from those and insert those into my Data Set.
NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.
Check out what I’m trying to do, maybe you can help?
First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.aspdotnet-suresh offers C#articles and tutorials,csharp dot net,articles and tutorials, VB.This article explains how to perform insert, update and delete operations in ASP. Let us take an example to perform CRUD operations using Entity Framework Database First approach.The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.
