IMPORTANT INFORMATION ON USING THE TELERIK REPORTING FORUMS

The goal of the Telerik Forum is to provide all registered users with a way to find answers to their questions before officially contacting Telerik. In case you need a faster and precise response, please start a new support ticket as it gets higher priority than Forum posts.

A post in the Forums doesn't guarantee you a response from the Telerik support team although 95% of all posts are eventually addressed. Additionally, a post is not assigned a response time as with the support ticketing system.

The Forums can be used to:

Discuss coding techniques with fellow Telerik users
Share your experience on the Telerik suite of controls
Contact Telerik with a question
Contact Telerik MVPs
Help other users

Telerik strives to constantly improve its support services but it is essential to have full information to supply precise replies. If we do not have enough details we will not be able to properly address your inquiry and we will ask for further info. The extra loop is sure to slow down the time it takes to resolve your problem, and subsequently the further development of your project.

It is vital that you follow these guidelines in order to receive an accurate response:

Change text at runtime?

Hello (again) -

On my report's page header, I have a text box and when the report is generated, the text value needs to change depending on the item from a drop-down list on the web page.

I have tried a few ways to get this to work but I have not been succesful. Does anyone know of a way to do this with the report control on a web page? I can save the drop-down list selected value as a Session variable if necessary.

Thanks
- will

Preview and HTML Preview

Hello
    I am having a number of problems with the preview and html preview.

    Initially I was getting "reporting the source of the report definition has not been specified"

    I removed all my data fields and my odbcdataadapter and it started to display a preview. I then add a number of additional textboxes and an picture box (with image set) and the preview no longer updates.

    I have tried rebuild solution but the preview no longer changes.

    Any ideas would be appreciated.

Cannot generate Quick Start tutorial report

I'm trying out the Telerik Reporting software. Everytime I try to display a report that I've created I get the same error...

System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.Reporting.ImageRendering.CanvasBase.MeasureString(...)

...and the error message goes on much longer than that.

I even get this error when following the Quick Start tutorial.

Can someone help me out so I can evaluate whether or not Telerik Reporting is suitable for my project.

Thanks, Bryan

Help urgently needed

I need help figuring out why the following code does not work:

I eventually get an out of memory exception on this:

    private void ShowReport(DataTable mydt1)  

    {  

        try 

        {  

            Report report = new Report();  

            DetailSection detail = new DetailSection();  

            Telerik.Reporting.ReportItemBase[] mylist = new ReportItemBase[mydt1.Columns.Count];  

            int icol = 0;  

            foreach (DataColumn col in mydt1.Columns)  

            {  

                mylist[icol] = createtextbox(col.ColumnName.ToString());  

                icol++;  

                //detail.ColumnCount++;  

            }  

            detail.Items.AddRange(mylist);  

            report.DataMember = "HIPAAlog";  

            report.DataSource = mydt1;  

            report.Items.Add((ReportItemBase)detail);  

            detail.KeepTogether = false;              

            ReportViewer1.Report = report;  

            ReportViewer1.Visible = true;  

        }  

        catch (Exception ex)  

        {  

            throw (ex);  

        }  

    }

But if I use:

    private void ShowReport(DataTable mydt1)  

    {  

        try 

        {  

            Report report = new Report();  

            //DetailSection detail = new DetailSection();  

            //Telerik.Reporting.ReportItemBase[] mylist = new ReportItemBase[mydt1.Columns.Count];  

            //int icol = 0;  

            //foreach (DataColumn col in mydt1.Columns)  

            //{  

            //    mylist[icol] = createtextbox(col.ColumnName.ToString());  

            //    icol++;  

            //    //detail.ColumnCount++;  

            //}  

            //detail.Items.AddRange(mylist);  

            report.DataMember = "HIPAAlog";  

            report.DataSource = mydt1;  

            //report.Items.Add((ReportItemBase)detail);  

            detail.KeepTogether = false;              

            ReportViewer1.Report = report;  

            ReportViewer1.Visible = true;  

        }  

        catch (Exception ex)  

        {  

            throw (ex);  

        }  

    }

It works, except nothing is displayed! I get no data in the report (should be over 3,00 hits...) So what the heck am I missing? It should be a fairly straight forward deal. I take a bunch of data, put it in a datatable, and then try to greate a dynamic multi-column report out of it...

OH!
Here is a function I missed posting..

    private Telerik.Reporting.TextBox createtextbox(string FieldName)  

    {  

        Telerik.Reporting.TextBox textBox2 = new Telerik.Reporting.TextBox();  

        textBox2.Value = "=[" + FieldName + "]";  

        textBox2.TextWrap = false;  

        textBox2.CanGrow = true;  

        textBox2.CanShrink = true;  

        return textBox2;  

    }

Image Quality / DPI

Hi,
I want to generate maps that fit perfect into the PictureBox. Therefore I need the pixel size of the Picture Box. The size of Picture Boxes are typically given in inch or cm. Do you have any ideas how to calculate the pixel size? Is there a way to configure the image quality (DPI) ?
Sincerely,
Alexander Brütt

Strange issue with building PDF programmatically

Hello! I'm attempting to build a simple set of reports against a development project that is currently using SQL Reporting 2005, which has some shortcomings I think your product may handily overcome.... if I can only figure out what I'm doing wrong here.

My web app needs to generate PDF reports and display them to the user. Here's the code I'm trying to use against the telerik Reporting. Note that I'm trying to pull the rendered PDF into a byte array and pass that array directly to the context.Response object. (This is very similar to what I do with SSRS, which is working.) Unfortunately, with the telerik report in the code below, when the Adobe Reader opens on the client's system, an error message pops up that reads "there was an error opening this document. The file is damaged and could not be repaired." (This was with Adobe Reader 7.0.8 by the way.)

Note that there's some lines in the code below that are commented out - these are pulling the PDF into a FileStream and writing it to a file - if I try to open the file thus created, it works like a charm!! (same version of the reader.)

I'd like to avoid all that sloppy file writing... any ideas what in the world I'm doing wrong here????

Oh, and thanks for letting us use the beta of what looks to be a fabulous product... I was sold as soon as I realized the codebehind was C# and not some horrible VBA like what SSRS uses!

JobList report = new JobList();  

string mimeType = string.Empty;  

string extension = string.Empty;  

Encoding encoding = null;  

byte[] RenderedRptArr = Telerik.Reporting.Processing.ReportProcessor.Render("PDF", report, null, out mimeType, out extension, out encoding);  

//FileStream sOut = new FileStream("c:\\dev\\joblist.pdf", FileMode.CreateNew, FileAccess.Write);  

//sOut.Write(RenderedRptArr, 0, RenderedRptArr.Length);  

//sOut.Close();  

System.Web.HttpContext context = System.Web.HttpContext.Current;  

string strPath = context.Request.ApplicationPath;  

Response.AppendHeader("content-disposition", "attachment; filename=JobList.pdf");  

Response.Clear();  

Response.ContentType = "application/pdf";  

context.Response.BinaryWrite(RenderedRptArr);  

Response.Flush();
