Just one note: The previous way to use ID and name was better. You should not use name as a unique key in your data. The name can change in time whereas the ID is unique and constant...<br />
<br />
IDictionary always requires two arguments - that's the way all dictionaries work. If you need just one argument use IList or ICollection.<br />

I thought the ID and Name were better also. &nbsp;I did get this to work by using the two arguments. &nbsp;I used the same parameter for both. &nbsp;I wasn't able to get the supervisor to add the ID to the table. &nbsp;So, will do it her way. &nbsp;Thank you for the response. &nbsp;Happy New Year.

The application I'm working on runs a report in SSRS. &nbsp;I'm adding the parameters for a dropdown list. &nbsp;The way that I'm pulling the list from the database has changed. &nbsp;I'm now pulling a list of instructors from a table that only has the instructor name and no id, as I used before. &nbsp;I was pulling and using the instructor ID and instructor Name for the key and value. &nbsp;I now have only the instructor name. &nbsp;So, I changed all of the entries in the application to have only a single string. and am using the <br />
CONSTANT_DROPDOWNLIST_VALU<wbr />E_NAME_Dro<wbr />pDownList_<wbr />Instructor<wbr />s. &nbsp;However, I do get the error that it using the generic IDictionary requires 2 arguments. &nbsp;It wants me to create a new class or type. &nbsp;I've done a search in the application to find all code for the dropdownlist and changed them all. &nbsp;Not sure what I need to do. &nbsp;I've tried creating the class and that does clear the error. &nbsp;But I'm not sure what to put in that class.

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.
