How to Pass a value to rdlc TextBox from codebehind

Hi and sorry for my english.

You can use a ReportParameter Like this :

List<ReportParameter> ListParameters = new List<ReportParameter>();
ReportParameter parameter = new ReportParameter();
parameter .Name = "name";
parameter.Values.Add("Value");
reportViewer1.LocalReport.SetParameters(ListParameters);

In the report.rdlc, you will just add a new parameter with name "name".

1.Go to the rdlc Design view
2.on the report data view (On the left) select parameters
3.Right click Add
4.set the name (best you Check Allow blank and allow null value)click OK

5.add the textfiled value OR select one from your tablix,right click and select Expression
6.set the expression e.g

=Parameters!title.Value

7.In your form that contains your report view add the following lines for a single parameter

ReportParameter rp = new ReportParameter("title", title);

          this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rp });
         });



          reportViewer1.RefreshReport();

8.for multiple parameters

ReportParameter rp = new ReportParameter("title", title);
          ReportParameter rps  = new ReportParameter("expense", totalExpense.ToString());
          this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rp });
          this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rps });



          reportViewer1.RefreshReport();
