Forms Data Controls :: Can't Clear Items Repeater Control?
May 7, 2010
I've read that you should write repeaterControl.DataSource = null to clear the items in the control, but it doesn't work. Does anyone have any tips or links to articles about this problem?
I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions. I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater.
I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there would be a big problem with memory.
I have an xml repeater deployed on two different pages. On the "News" page, I'd like to show all the items (which works fine), but on the "Home" page I'd only like to display the three most recent items.The code I'm using is below.
Here is the situation I have, I have a repeater inside a Usercontrol. The datasource is a IEnumerable<Investor> Exposed through a UserControl's Property. I have overridden the UserControl's databind event to set the Repeater Datasource before databinding the repeater. When it's not a postback, it databinds find and the events on the repeater item's controls fires up fine. But there is one event on repeater items (Delete Investor) which call back the DataBind of the UserControl after removing the Investor from de datasource. When this Event is called, it does all the work (deleting the investor and so on...) calls back the usercontrol's databind but when (within the usercontrol databind) the repeater is databinded again, the repeater items doesn't update (repeater items for investor not on the DataSource anymore still appears). My ItemDataBind doesn't even fire by then.

I Tried with both the Repeater Item Command and each LinkButton Event to see if it would make any difference, but none worked
This should give me the friends of the user currently logged in in the Repeater, but gives me an exception on the runtime that an instance needs to be initialized, can you please suggest a solution...
Also, what should be the value of the NavigateUrl property of a Hyperlink in an ItemTemplate if the url is:
"http://domain.com/viewprofile.aspx?id=" + 'THE UserID property of the current element in the list'

I am trying to experiment with things as a beginner and want to use paging in Repeater Control. Since Repeater control is light weight, I want to use that. I have heard of two methods: PagedDataSource class and the other that I dont remember. I wanted to attempt both of them. How do I proceed?
