SSRS下拉菜单和输入参数

Question

I am creating an SSRS report in Visual Studio 2008 and I was wondering if it is possible to have a drop down parameter that also allows user input. I have done a lot of research and haven't found anything that talks about this issue.

I have a multi-value drop down parameter that is populated through a query. I would like my user to be able to input a new value and use that along with the other values that are already populated in the drop down menu.

Any help and/or suggestions are appreciated!

Answer 1

I would create a new Parameter before the existing multi-value parameter. This would be a single-value with no associated dataset.

Then in the current query driving the multi-value parameter, I would add a UNION ALL clause to add a single row for the input value.
