reload the page with dyanamic content based on user link click

07Raghav · August 15th, 2013, 05:09 AM

I am having a listview on a page displaying title of articles[news].

I want to display by default the top news[along with full article] in the adjoining section.
Further i want to update the adjoining section[one with full description] based on user link click in the title only section.

I first thought of implementing the objective via the same method as described on page-464 [customizing the detailsview & handling its events] but it has the dropdownlist items bound to db whereas i am not having dropdownlist so cant bind.

Can any please guide me to relevant code or implementation or how shall i proceed.

Will be a great help. Thanks.

Hi ok are there any suggestions how can i open a new page based on link click and fetch data based on the link clicked previously ?? [Just like blogs] Thanks

Hi there,

Can you explain what it is you're trying to accomplish? I don't understand what you want which makes it impossible to suggest something. Also, why doesn't the example in the book work for you?

hello Imar actually i have gone through the book and am currently eperimenting/learning by making demo projects.

Here is what i have found to be a solution just now:

I want a link which is dynamically generated and points to another page where its[link's] value is used to retrieve data from db.

Quote:

<asp:Hyperlink runat= "server" Text='<%# DataBinder.Eval(Container.DataItem,"Results")%>' NavigateUrl='<%# "Testpage2.aspx?id=" + DataBinder.Eval (Container.DataItem,"ID")%>' ID="Link2" />

But also learnt that it's unsafe [subject to injections.]

Please please please, just spend few minutes of your precious time to point me any direction to go.

Would love to, if I knew what help you needed.

The example you posted should work. What;s wrong with it? Why doesn't it work or why would it be unsafe?

BTW: Is Exercise 3 of Chapter 14 what you're looking for?

sir at first i tried to base out mine problems solution on the try out in chapter 13 [page 464] customizing the details view and handling its events where you have shown how to bind db to dropdown list

but then i realised a better solution would be to load a new page with the id of the dynamic link.

1) mine page is having listview [for news titles/headings]
2) i want to open a new page based on the link click[for news details]
3) in the newly opened page i want to fill the listview item template with the news details

problem:

how to open a new page based on link click and use the id of the link to fetch data

-------------------
edit:

the other user probably more experienced says it's unsafe in comments here :http://stackoverflow.com/a/9606848/1936980

the answer i found : http://stackoverflow.com/a/9636024/1936980

if you have posted any blog or article to tackle any similiar issue would be very helpful

Did you see the exercise I referred to? It explains exactly how to do it.

That solution is safe as the ID is passed from page to page and then converted into an integer before it's used.

Cheers,

Thanks for your help sir, will look into it. Please also do consider writing books on more subjects.. like ajax, jquery or db.

If only there were 36 hours in a day ;-)

I hope to have addressed these topics with dedicated chapters in the book....

Cheers.
