Datalist and container.dataitem problem

[Chumley the Walrus]

I have a datalist, and I need to display the appropriate weekday
contigent upon the date that exists in my 'showdate' record (which is
a datetime datatype):

<%
if weekday(Container.dataItem("showdate")) = 2 then
response.write "monday"
end if %>

.....gives me a "Container is not declared" error

?????

you have to use DataBinding syntax ( <%#%> )

you have to use DataBinding syntax ( <%#%> )

no, that doesnt work in this context. Error will state : Statement end
expected. I Need to find a way to use Container.dataItem("showdate")
in a way to manipulate the data and do something with it besides
display it in a datalist.

 

[Konrad Rotuski]

<%#DataBinder.Eval(Container.DataItem, "showdate")%>

DataBinding expression has to return value, not response.write

just return as string what response.write was writing, it should work that
way

for Container.DataItem as DataRowView :

Protected Function ReturnString(drv as DataRowView) As String
if weekday(drv("showdate")) = 2 then
return "monday"
else
return String.Empty
end if
End Function

and in aspx :

<%#ReturnString(Container.DataItem)%>

it worked for me always

HTH

How do you declare "drv" with this function?
I'm getting an error : Specified cast is not valid

you can put here byval, i was writing this by hand, so vs.net didn't put it
there

I'm getting an error : Specified cast is not valid

thats because Container.DataItem is not DataRowView, if you are binding
datatable then you will get DataRowView, what do you bind to datalist ?

look here for more Container.DataItem info :
