Asp net detailsview itemupdating tahmoh penikett dating
Here is my detailsview: I tried adding a label to my page and then once updated Name had been assigned the value of the textbox I tried assigning that value to the label and it printed out the old product name not the one in the textbox.I can't see anything wrong with the code and it's driving me mad. hi, i think you miss something, try to see the table where you save the value of the fields you entered if it change anything, if it change anything, then you have put some code on your SP that retrieves data after the UPDATE code that you have.
Before we write any code, let’s see what this edit mode looks like. The events that end in “ing” are fired just before their past-tense counterparts, and should be handled only if you want to implement some logic to determine whether the action in question should be performed.
The difference is that now you can easily refer to these inner controls from your code, you can easily change their appearance using custom HTML code, and, if you wish, you can replace them with totally different controls. For example, you can widen the controls that are used to edit the fields, as well as performing other kinds of customizations.
You can also give specific IDs to the inner template controls, rather than using their default generic names, so that you can find them easily when you need to. Adding the code to update the rest of the fields is easy, so we’ve left it as a task for you to complete on your own. ), don’t forget to update the stored procedure in the database as well as the code-behind file.
方法：用到控件中的Hyperlink Field--作用是将某一列设置为超链接状态 Data Text Field--要绑定的列名或属性名 Data Navigate Url Field--超链接要传的值，一般绑定主键 Data Navigate Url Format String--超链接传值的格式--要连接的地址?
id= --是占位符，，占的是Data Navigate Url Field的值 注：在Grid View配合Details View使用中 Grid View只实现删除的方法，Details View实现增、改的方法 Grid View跳转到Details View是要将设置好的Data Navigate Url Field中的主键值传递给Details View， Details View配置数据源时定义来源是Query String 键的名字--要连接的地址?
Hi While working with Details View control I have come up with few resources when you want to perform update to the data within Details View using buttons out side of Details View control.
