Hello All,
I use a repeater control to display data, here is line I use to output
data

<%# ((DataRowView)Container.DataItem)["sItemDesc"]%>

now the issue is that this is a description field and I only want to display
the first twenty words of the description, how can I do that ? can I alter
the above command to do that, or do I need to do that in SQL ?

Change:

<%# ((DataRowView)Container.DataItem)["sItemDesc"]%>

To:

<%# Get20WordDescription(((DataRowView)Container.DataItem)["sItemDesc"])%>

and add a method in your page:

protected string Get20WordDescription(string val)
{
string[] parts = val.Split(' ');
if (parts.Length > 20)
{
string[] subParts = new string[20];
parts.CopyTo(subParts);
return String.Concat(subParts);
}
return val;
}

My Get20WordDescription is very much a hack, so if you spend some time I'm
sure you can come up with something much better.

Thank you so very much Brock for coming back to me again
I tried this one out, and get this error for some strange reason, any tips
as to why this is happening and how to sort it out?

Error 2 The best overloaded method match for
'showitems.Get20WordDescription(string)' has some invalid arguments

Oh yea -- do this instead (I'm assuming the column is a string and is never
DB null):

Get20WordDescription((((DataRowView)Container.DataItem)["sItemDesc"]).ToString())%>
