how do I pass a parameter from web.config AppSettings to a SqlDataSource?

Define your app settings normally, then you can access them from your codebehind like this

string strVal = system.Configuration.ConfigurationManager.AppSettings("STATUS_ID")

Select allOpen in new window

I want to do it from the .aspx, is that possible?

see if you can:

 <asp:Parameter DefaultValue="<%# system.Configuration.ConfigurationManager.AppSettings("STATUS_ID") %>"  Type="int32" Name="StatusID" />

if not, then i would say stick with code-behind.

Yes, you can, but you will still need to code some codebehind.

First declare a property like this, in your codebehind, this will get the appsettings val

          public string StatusId
          {
              get
              {
                  return system.Configuration.ConfigurationManager.AppSettings("STATUS_ID");
              }
          }

Now you can access the StatusId property in your aspx (markup page)

<%# StatusId()%>

for example if you want to set the text of a label

text='<%# TypeCode()%>'

can I put that codebehind in the a file in the App_Code directory so I don't have to modify every file?

The best thing would be to put it in a common class

thanks, I was getting an unrelated error and after going back through it it's working. thanks!
