Introduction:
In this article I will explain how to add checkboxes in asp.net gridview and get gridview selected rows data on button click in asp.net and then we can work with the data for further processing.
In this article I will explain how to add checkboxes in asp.net gridview and get gridview selected rows data on button click in asp.net and then we can work with the data for further processing.
Following
Steps we will cover in this article:
1.
Create Dynamic table in code behind in asp.net.
2.
Use that table as data source for gridview.
3.
Add check boxes in gridview.
4.
Get selected row value from gridview on button
click.
5.
Show selected value in Label Control in asp.net.
