Hello,

I want to create a report viewer parameter combo box but can't seem to figure out a certain part of doing it.  When I'm creating the report parameter, how do I choose the values for the combo box?  I.e. I need a combo box where the user can choose between two values which are "Summary" and "Detailed".  I tried putting those values into an array and assigning it to the AvailableValues.DataSource but that didn't work because it then asks me to fill DisplayMember and ValueMember (which is a problem because an Array doesn't have column names, which is what DisplayMember and ValueMember want).  I also can't find a single example of how to do this.  Anyone know how to do this?

Hello ryan,

If you're using an array, clearly the ValueMember and DisplayMember would match, so the correct syntax is:

string[] myarray = new string[2] { "Summary", "Detailed" };
this.ReportParameters[0].AvailableValues.DataSource = myarray;
this.ReportParameters[0].AvailableValues.ValueMember = "=Fields.Item";
