View 4 RepliesI'm working on a project where we're using Windows Desktop Search (WDS) to index files on a web share and then later allow the user to search via a website for documents in the share.
These documents are transferred to the share via FTP, however it would seem that either the computer never goes idle to index or at some point the indexing stops. Is there a way from the command line or within the program itself to force this to happen without having to re-invent the wheel? Using .NET 3.5 and C#.
why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
