same problem hi! i have the same problem as you do. if you find the solution, will you please email me at lala_23_ph@yahoo.com. i'll also post here if i find the answer. thanks!

Anybody here knows where i could download for free a book on crystal reports .net? I've downloaded Brian Bischof's ebook but it contains only 2 chapters. If i'm not mistaken, the whole book could be dowloaded for free before...so maybe somebody here has downloaded it. i really need a copy of the book. my email is lala_23_ph@yahoo.com. Thanks!

Found the answer to Parameter Passing Prob I learned this from Brian Bischof's ebook which you can download at his website: http://www.crystalreportsbook.com/ You should do all your runtime customization before you preview your report in the CR Viewer. My code is below... ParameterFields paramFields = new ParameterFields(); ParameterField paramField= new ParameterField(); ParameterDiscreteValue discValue = new ParameterDiscreteValue(); paramField.ParameterFieldName = "Product"; discValue.Value = textBox1.Text; paramField.CurrentValues.Add (discValue); paramFields.Add(paramField); viewer1.ParameterFieldInfo = paramFields; viewer1.ReportSource = new CrystalReport1();

I'm new to C# .Net and Crystal Reports for .Net. (1) I'm having problems in setting parameter fields at runtime. I used the code at the msdn documentation but it doesn't work for me. What I want to happen is to get the value of the parameter supplied by the user through a textbox, instead of having the parameter dialog box prompt the user for input. But the dialog box still pops up. What wrong with my code? (see below...) Another thing is that the ParameterFieldName property (and the other properties such as CurrentValues,MinimumValue,etc.) of the ParameterField Variable I declared is not available for selection in the intellisense...it's replaced by set_ParameterFieldName/get_ParameterFieldName...(set_CurrentValues, etc.). How can I correct this? (2) I published my report as a web service so I'm using the crystal report viewer in making runtime customizations. Is there a way that I could use the report engine object model instead, so I could have access to all the properties and methods needed to customize the report in code? I pasted my code below. Hope you can help me.
