ViewState Code

I have the following code in an aspx page and I'm not sure what it's doing.

if (ViewState["COOLEnabled"].ToString().ToUpper() == "YES")
            ddlSFCOOL.Enabled = bEnabled;
            ddlSFCOOL.Enabled = false;

any help will be appreciated.

Hello, somewhere your page must be setting that viewstate value:
ViewState["COOLEnabled"] = "yes";

Open in new window

Then in another place of your page that code (your example) check for that value to decide enable/disable your ddlSFCOOL control.

The ViewState object is like your Session object, but it values dont reside in the server, instead these values are saved in your page, this mean that they dont expires when your session does.
