Introduction

This article describes how to get and set the parameter value from the report:

Example

This example is composed of:

  1. A sample report 

  2. A form that loads the report automatically and shows the preview report

  3. A button that retrieves the parameter's actual value using the method:

    private string GetParamValue (string paramName)
    {
        string tmpValue="";
        for(int i=0;i<ReportDoc.DataDefinition.FormulaFields.Count; i++)
        {
            if(ReportDoc.DataDefinition.FormulaFields[i].FormulaName==
    						"{" + paramName + "}")
            tmpValue= ReportDoc.DataDefinition.FormulaFields[i].Text ;
        }
        return tmpValue;
    }
  4. Another button that changes the values of the report using the textbox text:

    private void SetParamValue (string paramName, string paramValue)
    {
        for(int i=0;i<ReportDoc.DataDefinition.FormulaFields.Count; i++)
        if(ReportDoc.DataDefinition.FormulaFields[i].FormulaName==
    					"{" + paramName + "}")
        ReportDoc.DataDefinition.FormulaFields[i].Text = "\"" +paramValue +"\"";
    }
