Convert images/pdfs to report.

Hi guys,

I have a business request of being able to generate reports from images or pdfs and add watermarking or custom texts to the reports that will finally be printable/exportable in pdf on the web.

I was wondering if it's possible to do so and would like some input from the forums on whether the reporting tool is a good solution for such a request. ( This is because I would like to use of the wonderful reporting viewer control for preview/printing/exporting to pdf)

A typical scenario would have probably a list of image files or mutliple pdf files ( with many pages inside) where I would like to add to the report which would definitely have a header/footer custom text and needs to have a watermark imprint on the report itself. The size of the image is not fixed and will need to be resized to fill up 1 typical report page

If its possible to do so, can someone direct me with some form of pseudo code or code samples especially in the part where I iterate through the pages in the pdf to add to the report.

If its not possible to do so, can someone direct me to any good telerik control from the asp.net ajax suite that might be able to perform what I just listed above. - or any other 3rd party tool.

I have been using Telerik reporting for all our business requirements and would prefer to continue doing so and would like some help with how I can include all the pages in the pdfs or a List<image> into the report as well as defining the size of the image to fit nicely in a portrait A4 size when being printed.

Regards

Jonathan

List data source parameter

It is userObjectDataSource (IList<User> GetUsers()) as report DataSource. Also it is a List in details report section and it is an ObjectDataSource (IList<string> GetPrivileges(int userId)) as DataSource for this List. How can I set UserId from userObjectDataSource as value for parameter of ObjectDataSource? I tried ObjectDataSource->Parameters->Value-><Expression>->Fields, but - No Data Source found. It should be one list of privileges for each user. Implementation through SubReport incorrect displayed after export in to PDF or TIFF. Can you help me?

Chart data labels and legend

I'm trying to create test report with chart and here what I have:

this.chart3.BitmapResolution = 96F;

this.chart3.ChartTitle.Appearance.Visible = false;

this.chart3.ChartTitle.Visible = false;

this.chart3.DataSource = this.sqlDataSource2;

this.chart3.DefaultType = Telerik.Reporting.Charting.ChartSeriesType.Pie;

this.chart3.ImageFormat = System.Drawing.Imaging.ImageFormat.Emf;

this.chart3.Location = new Telerik.Reporting.Drawing.PointU(new Telerik.Reporting.Drawing.Unit(0D, Telerik.Reporting.Drawing.UnitType.Inch), new Telerik.Reporting.Drawing.Unit(7.800079345703125D, Telerik.Reporting.Drawing.UnitType.Inch));

this.chart3.Name = "chart3";

chartMargins5.Bottom = new Telerik.Reporting.Charting.Styles.Unit(1D, Telerik.Reporting.Charting.Styles.UnitType.Percentage);

chartMargins5.Left = new Telerik.Reporting.Charting.Styles.Unit(1D, Telerik.Reporting.Charting.Styles.UnitType.Percentage);

chartMargins5.Right = new Telerik.Reporting.Charting.Styles.Unit(24D, Telerik.Reporting.Charting.Styles.UnitType.Percentage);

chartMargins5.Top = new Telerik.Reporting.Charting.Styles.Unit(1D, Telerik.Reporting.Charting.Styles.UnitType.Percentage);

this.chart3.PlotArea.Appearance.Dimensions.Margins = chartMargins5;

this.chart3.PlotArea.XAxis.MinValue = 1D;

chartSeries1.Appearance.LegendDisplayMode = Telerik.Reporting.Charting.ChartSeriesLegendDisplayMode.ItemLabels;

chartSeries1.Appearance.ShowLabelConnectors = true;

chartSeries1.DataLabelsColumn = "Department";

chartSeries1.DataYColumn = "TotalJobs";

chartSeries1.Name = "Jobs";

chartSeries1.Type = Telerik.Reporting.Charting.ChartSeriesType.Pie;

this.chart3.Series.AddRange(new Telerik.Reporting.Charting.ChartSeries[] {

chartSeries1});

this.chart3.Size = new Telerik.Reporting.Drawing.SizeU(new Telerik.Reporting.Drawing.Unit(5.7999601364135742D, Telerik.Reporting.Drawing.UnitType.Inch), new Telerik.Reporting.Drawing.Unit(2.8998820781707764D, Telerik.Reporting.Drawing.UnitType.Inch));

Result attached in TelerikReports-chart file.

My questions:
1) How I can fix data labels? Right now some of them overlay other. See "Human Resources" and "Healthcare" at the bottom of img.
2) I want to display numbers in data labels and text in legend. For example "Sales/Marketing" should be replaced to 60, but legend should be the same.

Thanks

Running report prevents callbacks

Hi All,
I am using telerik webform report viewer version 5.1.11.713 and the corresponding Reporting dll's.
I am having issues with enabling a user to close down a report and continue using the ajaxified web application.
I use the radwindow to load an aspx page that contains the web viewer. In the Page_Load event, I assign my report document to it.
Some reports may take a couple of minutes to run, and the user may close the radwindow in order to do another task. It would be expected that the user not receive the report.
The thing is, if the user clicks a button that uses a callback, that callback waits until the Report has completed.
This is unexpected.
Is this the intent of the Report mechanism? Elsewhere, if a callback is triggered while another callback is being processed, the new callback takes precedence.
Can you please advise as to what can be done to alleviate this issue?
Thanks,
Steele.
