This is a very first time I am going to share entire project
instead of Code Snippet.
During my last project, I face a requirement in which I have
to display grouped data into grid, after referring various possible solutions,
I decided to go with Gridview and Repeater as a Column of the grid. Thus I can get benefits of Gridview like
sorting, paging etc. easily and benefits of Repeater to show data with full
flexibility.
I think this would be a useful reference for all who are going
with similar kind of requirements. So please, if you like this post please share
and comment.
Step 1 : I
have one aspx web page and one data table as below. (In real life we can get
this from database as a datatable or entity). Here I am referring through List<Entity>.|
