Change Values Of ListView Elements In Codebehind

Apr 4, 2010

I'm trying to create a table with Listview and one of the fields I'm using is supposed to show a hyperlink to a more detailed view of the data shown, how I want to do that is by using FindControl on the ID of that item and then changing the value into a hyperlink of the detailed view page with a querystring attached, the problem is that I have no idea how to re-insert that data back into the listview field, which looks something like this:

<asp:Label ID="ViewLinkLabel" runat="server"
Text='[insert Link Here]' />

I'm still an amateur in ASP.net, and if any of this seems too convoluted when there's a much easier to do this that I don't know about.

Sep 5, 2010

While running ItemDetabound upon load of a listivew, I am trying to access the text in a label of the LayoutTemplate of a different Listview. It works fine if I try access the same labels under the same names if they are in the same listview, but not if they are in a different one. It was working for a while, can't figure out what I changed, but now says that object doesn't exist.

DataSource Controls :: SqlDataSource Returning Nothing When A SelectParamter Value Is Passed To A StoredProcedure?

Jan 14, 2010

- When I execute my query within Enterprise Manager giving the "Country" parameter a value of US, it returns the expected records

I have this as a parameter in the sproc:

@Country char(2) = NULL

and the relevant WHERE clause entry is:

AND (@Country IS NULL OR a.CountryCode = @Country)

My SelectParameter is:

asp:Parameter Name="Country" />

I've tried adding the "DefaultValue" property set to "US" and also tried setting it as sds.SelectParameters[4].DefaultValue="US"

When I do either of these things I get no records returned...

way to change a ListView into Insert Mode when linkbutton is not part of the ListView?
