Arraylist as repeater datasource (how to access from .aspx)
I have an arraylist:
Dim downloadsarray As New ArrayList
downloadsarray.Add(iconlink)
downloadsarray.Add(imgpath)
downloadsarray.Add(filesize)
downloadsarray.Add(description)
Which is the datasource of my repeater:
DownloadsRepeater.DataSource = downloadsarray
DownloadsRepeater.DataBind()
Please can you tell me how I output the items in the array to the .aspx page. I usually use (when using sqldatareader as datasource):
<%#Container.DataItem("1stcolumnnamestring")%>
<%#Container.DataItem("2ndcolumnnamestring")%>
But this does not work when using the arraylist as datasource.
Thanks.
ps... I know how to use <%#Container.DataItem%> to dump everything but I need to get at the items in the array individually, not have them all ditched out to the page i开发者_运维百科n one go. For example, item 1 contains a link, item 2 contains an image path, item 3 contains a description. I need to have them kick out in the correct order to build the link and icon correctly.
In your example, you should be able to do this:
<%# Container.DataItem.ToString() %>
Typically, when binding to a repeater, each data item holds the same type of data. In your example, each item is different - one is the link, one is the image path, etc. This is fine if all you want to display are those exact items (though I would then question whether you need a repeater to do the job).
If your intent is to show multiple links, you should create a class for each link and add instance of the class to your ArrayList:
class LinkThing {
string link;
string imagePath;
etc... (do all the usual stuff with properties and constructors)
}
downloadsarray.Add(new LinkThing(link1, path1, size1, desc1));
downloadsarray.Add(new LinkThing(link2, path2, size2, desc2));
and in the aspx page:
<%# ((LinkThing)Container.DataItem).link %>
<%# ((LinkThing)Container.DataItem).path %>
Try and use Container.DataItem that should get you the individual elements of the array list.
Try
<%# Eval(Container.DataItem) #%>
