推荐答案

您可以编写的所有内容都可以编辑，删除，但cmd行中唯一的变化

在页面加载中，您必须从表中提取数据.

you can write everything is same to edit,delete but the only changes in cmd line

In page load you have to reterive the data''s from table.

SqlCommand cmd=new SqlCommand("select * from UserCreation");

为了进行编辑，您需要使用cmd as
更新数据库.

and for edit something you need to update your database with cmd as

SqlCommand cmd=new SqlCommand("update UserCreation set columnname2= '"textbox2.Text'",columnname3='"textbox3.Text'" where columnname1= '"textbox1.Text'" ");

同样，要删除某些内容，您还需要使用cmd as
从数据库中删除.

similarly for delete something you also need to delete from database with cmd as

SqlCommand cmd=new SqlCommand("delete from UserCreation where columnname1= '"textbox1.Text'" ");

我认为这是一个简单的模型，您可能会有所想法.

This is simple model I think you may get some ideas.

单击编辑"按钮时，它的显示形式为空，因为页面已回发.因此，单击编辑"按钮时，您应将数据绑定到控件.

On click of Edit button its displyainng empthy form because page is post back .so on click of Edit button u should bind your data with controls .
