Silverlight Reporting

New Post: PageHeaderTemplate

Psychlist1972 — Fri, 05 Apr 2013 17:55:50 GMT

I've generally moved on from this sample, but couldn't find anyone in the community willing to take it on for any future updates.

The beauty is, for this sample, all the source is 100% available and you are free to do with it whatever you'd like. If you want to add in a feature urgently, the best person to do it will be you. If you want to contribute back to the sample, let me know and I'll add you to codeplex here.

Is there any event handler for report header like BeginBuildReportHeader.
It is very much required.
In my report in header i want to print report period and report for Department like...
Summary report for : Accounts
Summary Report From : 1/April/2013 To : 4/April/2013
etc.
Its very urgent.
Thanks in advance

New Post: Wpf version?

Psychlist1972 — Tue, 05 Mar 2013 16:53:17 GMT

The WPF printing model is quite different, so I didn't even attempt to do that. Plus, there are lots of report writing solutions for the desktop.

Commented Issue: Report Footer Totals [6]

Psychlist1972 — Tue, 14 Feb 2012 20:24:39 GMT

The data is pulled from Sql Server using stored procedute and the report printed all totals correctly, but without changing the page, if the report printed again, the totals are doubled, and when printed 3rd time, totals became 3 times and so on.
How to overcome this behaviour? I tried to re-create the object in BeginBuildReport method, but no luck.
Any solution?
Dega
Comments: Reset the totals to zero when the report has finished printing. The totals aren't anything magical, they're created in event handlers using variables. See the _totals variable. I'll update the source to do that as well.

Hi,

I'm using this and it works for me. One question, is it possible to add more binded data to PageHeader? I see you have an eventhandler for Footer.

Report.BeginBuildReportFooter += (s, e) =>
{
// set the running total as the context for the report footer
e.DataContext = _totals;
};

New Post: FYI on SL5 Printing issue

Psychlist1972 — Mon, 09 Jan 2012 21:55:56 GMT

Brought to my attention by @serbrech

https://connect.microsoft.com/VisualStudio/feedback/details/698140/printing-images-skips-pages-when-image-source-is-null

If the Source of an Image is null, the page that contains the image will not be printed (fails silently).
This happens when the runtime is Silverlight 5 (Vector printing). When the runtime is Silverlight 4, the page are rasterized as bitmap and all is fine.
Compiling with SL4 or SL5 RC tools produce the same behaviour.

A possible workaround is to wrap the Image control into another control that will swap a null Image source with a blank image.

I may make some changes to the sample in response to this.

New Post: Bound Grids -- not creating the right DesiredSize: Fail to page properly

mbcooper — Mon, 09 Jan 2012 21:40:06 GMT

Datagrid was easy because it was bound. This construct created the columns (up to 8) and rows (up to 30) .. so it really doesn't get that big.

Anyway, I modified the approach by creating an interface for the datacontext called "Clues", and put SuggestedHeight on the context if I feel it can't figure it out.

Also -- would be useful to do a scale transform if a single object could not fit.

I like your basic approach !

New Post: Bound Grids -- not creating the right DesiredSize: Fail to page properly

Psychlist1972 — Mon, 09 Jan 2012 21:36:26 GMT

Is there a specific reason you're using a DataGrid for this? The DataGrid is a pretty heavy control meant for interactivity.

I haven't tested the report with datagrids. Although there has been a request to be able to build a report based on one, using the grid itself for report display is not on my list.

Also, it looks like you're creating a separate datagrid for each row in the report. I'm not sure how big the report will be, but that could be a LOT of datagrids. Memory for the app would likely go a bit nuts.

New Post: Bound Grids -- not creating the right DesiredSize: Fail to page properly

mbcooper — Mon, 09 Jan 2012 20:17:58 GMT

I am building a fairly sophisticated (but not wildly so) report that has a variable number of rows and columns.

Unfortunately, as I walk through the "BuildReport" method, the DesiredSize of each row of information (which is bound to a datagrid) comes out at a measly 64 pixels (vs the 28 or so lines of data I have bound to it.

Is there a way to get the actual size sooner, so that the size is properly estimated and we trip teh "next page" concerpt.

Is this implementation such that any "unknown" binding size will not work ?

Here is my XAML for the report template:

          <!--Item template -->
                <reporting:Report.ItemTemplate>
                    <DataTemplate>
                        <!-- The Grid -->
                        <Grid >
                            <Grid.RowDefinitions>

                            </Grid.RowDefinitions>
                            <Grid   Grid.Row="0"
                                HorizontalAlignment="Stretch">

Closed Issue: NullReferenceException if some Templates are not set [2]

Psychlist1972 — Mon, 09 Jan 2012 04:45:29 GMT

The application/library throws an unhandled exception of type NullReferenceException whenever one of the following Templates are not set for a given Report instance: ReportFooterTemplate, PageHeaderTemplate, PageFooterTemplate.

This occurs at least in Report.BuildReport(Size) - e.g. if ReportFooterTemplate is not provided, it's thrown here:

FrameworkElement reportFooter = ReportFooterTemplate.LoadContent() as FrameworkElement;

The issue can be easily avoided by using empty templates though, thus I don't think this issue is important.

*Fixed issue with not being able to re-print the report. (and fixed leaky event handlers)
*Added null check on templates
