You don't have to send value to dropdown,
You have to make cascading dropdowns in the asp.net C# first, And get the values from there, and then pass to report parameter as:

//get 'selected value' or 'text' as per your need
var market = ddMarket.SelectedItem.Text; 
var customer = ddCustomer.SelectedItem.Text; 
List<ReportParameter> params = new List<ReportParameter>();
reportParams.Add(new ReportParameter("rptParamMarket", market));
reportParams.Add(new ReportParameter("rptParamCust", customer));
ReportViewer1.ShowParameterPrompts = false;
ReportViewer1.ServerReport.SetParameters(params);
ReportViewer1.ServerReport.Refresh();

Make sure "rptParamMarket" and "rptParamCust" matches that of the names of parameters in report.

That, in essence, means your report will be displayed based on the values you pass to it from the code behind.
