Created my first CR for Window Application, the problems is when i create a parameter i.e 'ClientName' and then run the report in Report Viewer the parameter dialog box appears however the Input field is displayed as dropdown and not textbox. 

 

Does anyone know why it displays as dropdown and not textbox, i have selected 'discreet value' when you create the parameter.

 

Also is there a way to populate a parameter dropdown dynamically in CR?

 

Thanks In Advance
