I have the object property StockContract.Dictionary which is a dictionary
collection of <string, string> key/value pairs. I need to be able to
retreive the keys and their values and display them on a page. I want to use
something like a repeater or something like that. I don't know if this would
be code I will have to manually write myself, or if it can be done with
dataBinding of some sort. I am using vs2008 and c# 3.5. Any ideas on how to
do something like this?

I tried to put the StockContract.Dictionary property as a
listView.DataSource. The compiler isn't complaining about it yet, but there
is another question about this kind of databinding. Inside the item
template, What do I use for the Eval() method to get the values out of the
Dictionary collection? I tried Eval("Keys") as the text for a Label control,
but that is what I litterally end up with as the text instead of the text of
the key. Any ideas how to deal with something like this?

I am trying to databind to the collection like you normally would say to a
database table. I need to cycle through all of the keys and print out their
key text and value text on a page. The print out has to be formatted with
html markup...

There seems to be a problem with the KeyValuePair<string, string> part. I am
not getting intelisense for the local variable defined as a KeyValuePair.

foreach(KeyValuePair<string, string> values in StockContract.Dictionary) {
Label1.Text = Values.key; //cant get intelisense for this line...

....
}

Hi Andy,

I was just trying to do this myself, and had some luck using the
ItemDataBound event:

MyRepeater.DataSource = dicTest;
rptBusinessTypes.ItemDataBound += new
RepeaterItemEventHandler(MyRepeater_ItemDataBound) ;
MyRepeater.DataBind();


void MyRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e){
//in the repeater ItemTemplate, you'll have a control
//called foo. I made mine an asp:Hyperlink.

HyperLink foo = e.Item.FindControl("foo") as HyperLink;
if(null != foo)
{
DictionaryEntry de = (DictionaryEntry)(e.Item.DataItem);
foo.Text = Convert.ToString(de.Value);
}
