Dynamically Resize images In Code Behind

What would be the most optimized way to resize an image for a PictureBox in Itemdatabound or itemDatabinding for a report? I have quite a few images and am tying not to have to manually resize them.

I seem to be missing something

    
                    private void detail_ItemDataBound(object sender, EventArgs e)  
        
                    {  
        
                        Telerik.Reporting.Processing.DetailSection procDetail = sender as Telerik.Reporting.Processing.DetailSection;  
        
                        Telerik.Reporting.Processing.PictureBox procPictureBox = procDetail.Items["pictureBox1"] as Telerik.Reporting.Processing.PictureBox;  
        
                        DataRowView row = procDetail.DataItem as DataRowView;  
        
                        string strPath = HttpContext.Current.Server.MapPath(@"~\Img\Product\" + (string)row["ProdImgLRes"]);  
        
                        using (Bitmap bmpIn = new Bitmap(System.Drawing.Image.FromFile(strPath)))  
        
                        {  
        
                            int w = bmpIn.Width;  
        
                            int h = bmpIn.Height;  
        
                            int intWidth = 90;  
        
                            int intHeight = (int)(h * intWidth) / w;  
        
                            Bitmap bmpOut = new Bitmap(intWidth, intHeight);  
        
                            using (Graphics g = Graphics.FromImage(bmpIn))  
        
                            {        
        
                                g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;  
        
                                g.DrawImage(bmpOut, 0, 0, intWidth, intHeight);  
        
                            }  
        
                            MemoryStream ms = new MemoryStream();  
        
                            bmpOut.Save(ms, ImageFormat.Bmp);  
        
                            procPictureBox.Image = Image.FromStream(ms);  
        
                        }

Thanks,
Dave

Cannot open Examples installed with App

I recently took over a machine from the developer that was using the Telerik RadControls for Ajax and Telerik Reporting controls. I attempted to open the examples installed in this directory: C:\Program Files\Telerik\Reporting Q2 2008\Examples\VB\ by clicking on the solution file. I used both VS2005 professional and VS2008. Each attempt gave me the following errors.

The application for project 'C:\Program Files\Telerik\Reporting Q2 2008\Examples\VB\WinDemo\VB.WinDemo.vbproj' is not installed.
Make sure the application for the project type (.vbproj) is installed.

I also received the error for these projects:
WebDemo
VB.ReportLibrary.vbproj

So I uninstalled Telerik Reporting and downloaded it again, and re-installed. No errors or warnings were observed during the installation. I then attempted to open the same solution with VS2005 and VS2008 with the same results.
My OS is Windows XP with SP3.

Thanks!

Cannot print a Report in the Trial version

Is it a bug or a design limitation of the Trial version that I cannot either print or save a report in PDF format?

Defining chart values when binding information.

Hi

I have been working with charting for telerik reporting, and I have to render a chart for each row in the report. The chart should display values depending on the values of the row. Is there a way to know the value of the row when the NeedDataSoourcet event of the chart is called?? or can I change the datasource of the Chart in the ItemDataBound or ItemDataBinding events of the detail section?? or Can this be accomplished by any way?

Thanks in advance.

Sorting on text parameters

Hi,

I'm trying to add a UI element to my report allowing users to select columns in the report to use for sorting.

Following the documentation I have successfully enabled the Parameters area in the report and a drop-down box duly appears containing the expected values. However, on first rendering the report a red circle appears next to the drop-down saying "invalid value" and no data appears in the report. First question is: how can I ensure unsorted values appear by default in the report as it loads?

More confusingly, although the report will successfully "preview" once a sort field has been selected, no sorting actually seems to occur. I've been messing around with the sort property of the report and I can't seem to get the syntax right to enable sorting. What I want to happen is for the ValueMember of the drop-down box DataSource to become the field used for sorting the data (the strings are identical) .. how can I achieve this?

(It's probably worth mentioning that some of the field names contain spaces, and the syntax I need for this is also confusing me ... is it Fields.fieldname with space or "Fields.fieldname with space" or Fields.[fieldname with space] or something else?)

Is there any way of getting a parameter from an external object - say a querystring on the page containing the ReportViewer and the passing it down to the report that the viewer is loading?

Cheers,
Matt

n-Tier Parameterized Reporting Web Application

Requirements
RadControls version	Q3 2008
.NET version	3.5 SP1
Visual Studio version	2008 SP1
programming language	ASP.NET, C#
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION
I have created a project to demonstrate how to have a n-Tier hierarchy (data layer, class library, web app) and use the Telerik Reports. This demo allows the user to pass in a parameter to the constructor of the report, which can then be used to retrieve data from the backend database. Currently the dataset is created manually for demo purposes but this could be extended easily to bring back data from SQL server. Also this demo illustrates the use of a SQL Server Session state and a unique Machine key for your web app. To use this functionality you need to run aspnet_regsql.exe against your database to generate the necessary tables for asp.net to use a database backend for credentials and session state.

the 3 relevant lines of code to change in the web.config (excluding the addition of a connection string entry, are

    
            <sessionState mode="SQLServer" allowCustomSqlDatabase="true" sqlConnectionString="ADD YOUR SQL CONNECTIONSTRING HERE" cookieless="UseCookies" timeout="60" regenerateExpiredSessionId="true"/> 
        
            ... 
        
            <machineKey validationKey="ADD YOUR VALIDATION KEY HERE" decryptionKey="ADD YOUR DECRYPTION KEY HERE" validation="SHA1"/> 
        
            ... 
        
            <authentication mode="Forms"> 
        
            </authentication>

Hope this helps someone as it took me a while to get this working the way I wanted it to.

Aniket
