批量编辑使用复选框更新ASP.NET gridview中的多行 [英] Bulk edit update multiple rows in ASP.NET gridview using checkboxes
问题描述
在下面的HTML标记我有一个简单的ASP.Net GridView有3列。
第一列包含CheckBox，第二列包含显示ID的标签和文件夹的Access Path分别和第三列包含Label和DropDownList，分别用于显示和编辑文件夹的状态。
这里我使用GridView进行分页显示数据，数据大约是数百万行。 当我点击提交按钮更新复选框选中的行时，执行时间过长会更新表中的行。
For示例：对于5000行= 26分钟。
任何人都可以帮我解决此问题并缩短执行时间，以便在几秒钟内更新所有记录。
我尝试过：
请参阅代码：
在这里输入代码

端
In the below HTML Markup I have a simple ASP.Net GridView with 3 columns.
First column containing the CheckBox, second column containing a Label for display ID and Access Path of the folder respectively and the third column containing a Label and DropDownList for display and edit status of the folder respectively.
Here I am using GridView with paging to display the data, and the data is about millions of rows. When I click on submit button to update the checkbox selected rows, execution time is taking too much to update the rows in table.
For Example: for 5000 rows = 26 min.
Can anyone help me to resolve this issue and reduce the execution time to update all the records within few seconds.
What I have tried:
Please see the code:
