Hi All,

I have a reporting page with a crosstab on it. Toggle Visibility action has been assigned to the Category field to drillthrough the Subcategory fields. Everything works well at this point. However, the report refreshes everytime the Category toggle mark is clicked.
I would like to ask if there is any option to store all retreived data by the first report generation to prevent the report being refreshed everytime the toggle mark is clicked.

Thank you.

Report not displaying data in Application

I created a POC report in the designer and it is working properly. I am now trying to implement this in a WPF application and have the report opening, just showing no data. (I am up to date using the Q3 2012) assemblies.

The ReportContent is being retrieved from a database. I am replacing the ConnectionString at runtime and have verified that it is being updated appropriately. At runtime ConnectionString="" is being updated to a valid connection string.

Also, I am not sure why, but if I do not remove "xmlns="http://schemas.telerik.com/reporting/2012/2" from the XML it will not even display the report and tell me that I have an invalid connection. Simply removing this at least allows the report to display, just with no data.

Here is a sample of the XML being pulled from the database:

<?xml version="1.0" encoding="utf-8"?>

<Report DataSourceName="TestConn" Width="6.45833333333333in" Name="Parent">

<DataSources>

<SqlDataSource ConnectionString="" SelectCommand="SELECT ID, CreateDate FROM tblTest WHERE ID= 1234" Name="TestConn" />

QR Barcodes

Does Telerik have any plans to add Qr-codes to the list of available bar codes? They seem to be gaining a lot of popularity (especially for scanning with phones) and are included in some of the competitors products.

Division always returns zero

I have an expression that uses division but it always returns zero. Here some examples of what I have tried:

=RunningValue('group1',Count(Fields.[Short Description])) / Exec('Report1', Count(Fields.[Short Description]))
Returns 0

=RunningValue('group1',Count(Fields.[Short Description])) / 64
Returns 0

=Count(Fields.[Short Description]) / Exec('DuplicateCARs', Count(Fields.[Short Description]))
Returns 0

=(3 /15)
Returns 0

The cell is formatted as a number with 2 decimal places assigned.

The running value does in fact return an int every time, I have tested it. So, why does this expression always return a zero? All other math opperators work fine; addition, multiplication and subtraction.

Instantiate Report Class Library from ASP.NET RadGrid

Hiya,

I been running through the Telerik RadGrid forum several times trying to find a scenario similar to no avail, therefore I'm hoping to seek some wisdom here. In my situation I'm using Telerik ASP.NET AJAX Q2 and Telerik Reporting Q3. I've created a test report class (Test.cs) which I intended to be used as report template for my RadGrid. The problem arises when I've finshed my Grid and my Reporting Class. I've yet to find a way to make RadGrid to pass over the data into the Reporting Class which should appear as PDF embedded in ReportViewer inside browser.

Basically I would like the grid to send the primary key value of the selected row to the reporting class library when a user clicked the ClientGridSelectColumn and clicked a "Print Selected" asp:LinkButton. I've gon through a couple of forum posts here such as here:
http://www.telerik.com/community/forums/reporting/telerik-reporting/radgrid-telerikreporting-interaction.aspx
and
http://www.telerik.com/help/aspnet-ajax/grid-retrieve-primary-key-field-values-for-items.html they did solve part of the problem however due to my lack of in depth understanding of telerik products the solution provided were not working as expected.

I hope someone could shed a little light to accomplish this task. Thanks in advance.

entitydatasource object context is empty

Hi!

I have a class library with my reports in it. I have another project where my entitymodel is in. In my reports project I've added a reference to the project where my entitymodel is in. I've also added the connection string to the reports project and rebuild the project. In my project I try to use an entitydatasource. I can select the connectionstring from the web.config, but if I click next, the Object Context is empty and I can't select anything.

Why is this happening and how can I fix it?

Multiple Page Excel Report

Hi. I'm currently using ActiveReports and considering switching to Telerik Reporting. One of the issues I am having is the ability to create an Excel report with multiple pages (sheets). The number of pages is unknown until the dataset is created. ActiveReports handles this, but with a restriction, when you export to XLS you cannot name the workbook sheets. Would Telerik Reporting allow me to do everything I can do already plus what I am missing?

1) Multiple reports combined inside a single export (workbook), XLS only
2) Each report has its own unique name and should be used as the sheet name

Thanks.
