我应该编写什么代码来更新Asp.Net中的Gridview控件中的数据？ [英] What Is The Code Should I Write To Update Data In A Gridview Control In Asp.Net?

问题描述

在我的程序中

i编写了用于插入，更新，删除操作和将数据显示到gridview控件的代码，但这里我的问题是当我同时更新/删除/插入记录gridview时应该更新它的细节。我应该编写什么代码？

提前谢谢

解决方案

你必须添加Gridview详细信息方法..



例如。



DataTable dt = new DataTable（）;

dt = ObjBAL。 methodname（）;

GV.DataSource = dt;

GV.Databind（）;



此类型Gridmethod，你应该在插入，更新，删除编码后调用..

这是一些通用代码：

< asp：GridView ID =   GridView1 
 runat =  < span class =code-string> server 
 DataSourceID =   SqlDataSource1 
 AutoGenerateColumns =   true 
 allowpaging =   true 
 PageSize =   50 
 AllowSorting =   true 
 DataKeyNames =   id 
 AutoGenerateEditButton =   true 
 AutoGenerateDeleteButton =   true 
 /> 
< asp：SqlDataSource 
 id =   SqlDataSource1 
 ConnectionString =  <％

in my program
i wrote the code for inserting,updating,deleting operations and displaying data into a gridview control but here my problem is when i update/delete/insert records at the same time the gridview should be update the details on it. what is the code i should write?
Thanks in advance

解决方案

You must add the Gridview details Method..

For example.

DataTable dt = new DataTable();
dt = ObjBAL.methodname();
GV.DataSource = dt;
GV.Databind();

This type of Gridmethod ,You should call after insertion,updation ,deletion coding..

Here is some general code:

<asp:GridView ID="GridView1"
        runat="server"
        DataSourceID="SqlDataSource1"
        AutoGenerateColumns="true"
        allowpaging="true"
        PageSize="50"
        AllowSorting="true"
        DataKeyNames="id"
