Asp.Net GridView - Need to add next and previous button in p

Question

Hi, I have account audit search page that display list of records in grid view. for example - name,Id,action etc. When I click on any row in grid view the details of that row I am displaying in another aspx page as popup.I have my grid view in audit search page and showing details in detailsModal page. When I am clicking on row in grid view I am passing rowId to detailsmodal page and in details modal page based on rowId I am fetching the data and showing it. for example - window.showModalDialog("DetailsModal.aspx?RowId=" + rowId, '', modalSize); Now I want to add next and previous button on detailsModal page so when I click on next button the next row of gridview should be displayed in detailsModal page and when I click on previous button the previous row of gridview should be displayed. What I have tried: Please suggest. It will be nice if I can get some sample code as example in solution.

Hi, There could be many solutions here but more appropriate one will be using PreviousPage.FindControl(). How this works: Using PreviousPage.FindControl() one can access PreviousPage data when someone navigates from Page A —> Transfer Data —> Page B. If one request a page directly, then PreviousPage renders null reference. Now use this:(e.g. if you have a datatable on previous page) previouspage.findcontrol( "testdatatable" ) as datatable; And once you have datatable you can easily move back and forth with the values. I hope this helps! Thanks!

Thanks Rajneesh. I can try this but how the Gridview pagination will work in this scenario.

Sorry for late reply. Have you visited this below link? https://www.aspsnippets.com/Articles/Access-Previous-Page-controls-in-ASPNet-using-C-and-VBNet.aspx This could be solution to your problem I think. But you can try this way too: so you have to do only task more particularly here and that is to send the data from one page another. You can send that all particular rowid to another page using Session or Cookies . You can send it as a object also. Like this: MyClass c1 = new MyClass(); Session[ "MyClass" ] = c1; //Next page MyClass c1 = Session[ "MyClass" ] as MyClass; if (c1 != null ) { ... } Let me know if you have any query. Thanks!

Thanks Rajneesh, I don’t have data table in my previous page. I am binding my grid view with ienumerable collection of audit class. I created a audit class with few properties. So I don’t think this will work. Can you please suggest me some other solution. I am passing grid view rowId Present in audit search page to audit detail page and in audit details page based on rowId I am again pulling data from collection and displaying it. My concern is in audit details page how will I get the rowId of next or previous row present in grid view present in audit search page.
