Problem with x-axis when exporting to PDF

I have a report that uses a line chart to show a trend of data across a date range. Code has been put in place to compensate for how the x-axis labels are rendered so that a large date range is readable. On the NeedDataSource event for the chart, I fetch the data then use the following code to adjust the x-axis label.

int labelStep = (dataList.Count / 10);

chartTrendByDay.DataSource = dataList;

if (labelStep == 0)

labelStep = 1;

chartTrendByDay.PlotArea.XAxis.LabelStep = labelStep;

When viewing the report in the ReportViewer, the above code results from 1..10 points on the x-axis. The problem is, when exporting to PDF I end up with 1 point for each day (i.e. a report for the trend across the year results in 365 data points), which is unreadable in most circumstances. See attached for the viewer-vs-PDF screenshots.

Question: How to I fix the export to PDF so that the x-axis is readable?

Asp.net Rendering

Hey Guys,
Thanks for optimizing the image rendering in the control, it appears much more responsive on image intensive reports even in debug mode here :)

So just for you internal stats to know HOW much better it is:

Q2 2010: 128 Http Requests, finish rendering in 17 seconds
Q2 2011: 105 Requests @ 7 Seconds

...very impressive performance boost.

Now I am seeing it request the header images on the viewer twice, so that's bloating the http requests, but they appear to be loading cached versions at least the second time...so while they're still processed there's no extra downloads. I can get this on Jing video if you want.

When can we expect to see spriting of the actual viewer control bar itself?

I cut the example below from your website, bur I am getting an error with 

the "Reports1.Filters.add("filter1") line. The error I get is:



<< Reference to a non-shared member requires an object reference. >>



What object requires referencing?



Thanks,

styling the <select all> text in the Silverlight ReportViewer

Hi,

I have created a custom style to change the look of the ReportViewer in my application. I am trying to see if I can change the text on the <select all> combo box item for a report parameter. From what I can tell, I need to apply a style to the Telerik.ReportViewer.Silverlight.MultivalueAvailableValuesParameterModel.SelectAllItem class, but I can't figure out how to get to it from Blend. It definitely isn't exposed by the ReportViewer class that I am currently styling. Is there a way to change this text at this point in time?

Thanks,

Rob

Conditional Formatting Rules

Hi,
I created a conditional formatting rules for subreport
where
expression = Fields.Item1
Operator = In
Value = 1,2,3
style.visisble = false

But the subreport still visible. If i create multiple rules using operator "=" then it works.
How can I use operator "In"?

Using EF DataSource for one entity plus children

I need to create a report that displays the details (including all children) for a single entity. I've got a method on my Object context that returns a single entity and I'm setting my entity datasource to that method. At runtime, I'd like to set the datasource in code to the current entity (which should already have all the navigation properties loaded, reducing the # of trips to the database).

I have a few questions:

1. Is it okay that I'm setting the datasource at designtime to a method that requires a parameter, but at runtime I set it to the entity (hence, no parameters needed)?

2. How do I show the details for the child collections? I'm guessing I will need subreports, but I'm not sure how to pass the child collection over. Will I need to use the NeedDataSource event? and if so, how do I use that and will I still be able to design the report using the designer?

3. How do I show/hide data? For example, one of my fields is a boolean value. Based on true or false of this field, I would like to show/hide (collapse) a certain area that displays several other fields. I read on another thread about setting the height of the details, but my data is in a panel (which I couldn't find a height property for).

Silverlight Report - Parameters not loading at first time or "Report is unavailable or session has expired." error

Hello,

Parameters are not loading at first time or ReportViewer presents a "Report is unavailable or session has expired." error message. After pressing the "Refresh report" button report is always presented correctly.

It happens like once per several tries, but still and it is unacceptable in a business solution.

Raport is generated dynamically, and all parameters are passed from ViewModel in this way:

private void RenderReportMethod(RenderBeginEventArgs rbea)<br>

{

if (rbea != null)

{

rbea.ParameterValues["Number"] = Invoice.Number;

.....(other parameters).....

}

We've already changed the default HTTPBinding settings in the ReportViewer

ReportServiceClient IReportServiceClientFactory.Create(System.Uri remoteAddress)

{

var binding = new BasicHttpBinding()

{

MaxBufferSize = int.MaxValue,

MaxReceivedMessageSize = int.MaxValue,

ReceiveTimeout = new TimeSpan(0, 15, 0),

SendTimeout = new TimeSpan(0, 15, 0)

};

var endpointAddress = new EndpointAddress(remoteAddress);

return new ReportServiceClient(binding, endpointAddress);

}

and in the webconfig where the ReportService is placed as well:

<bindings>

<basicHttpBinding>

<binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">

<readerQuotas maxStringContentLength="2147483647"/>

</binding>

</basicHttpBinding>

</bindings>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

<services>

<service

name="Telerik.Reporting.Service.ReportService"

behaviorConfiguration="ReportServiceBehavior">

<endpoint

address=""

binding="basicHttpBinding"

contract="Telerik.Reporting.Service.IReportService">

<identity>

<dns value="localhost" />

</identity>

</endpoint>

<endpoint

address="resources"

binding="webHttpBinding"

behaviorConfiguration="WebBehavior"

contract="Telerik.Reporting.Service.IResourceService"/>

<endpoint

address="mex"

binding="mexHttpBinding"

contract="IMetadataExchange" />

</service>

</services>

however the problem still exists.

Any ideas?
