Hello, 


I'm trying the transition from TelerikReporting Q3 2009 to Q1 SP1 2011 version. In my code I'm creating a Table Dynamically and Databinding it. 

Which results in the following exception:

[NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.Reporting.Processing.Table.MeasureColumns(Graphics graphics) +299

Thanks in advance.

I have a report that I created using the wizard. I set everything up to display the report in Landscape mode. When I preview the report, it always displays in Portrait mode. When I click on the page settings, it tells me that no printers are installed ( I have many printers installed). When I click on page settings again, it allows me to change to Landscape mode. If I export the report to Adobe, it exports in portrait mode also.

How can I set the report to preview and export in the correct orientation?

Hi,
Can I adjust this so the text doesn't wrap on the page size like it does in the image?

Hi,

Can anyone tell how to implement Group By on datatables using linq in telerik (C# Application).
I have written query as follows:

var query = from 

 

 

dataitem in combinedDataTable.AsEnumerable()  

 

 

 

group dataitem by dataitem.Field<string>("IONumber") into r

select new  

 

 

 

{

IONumber = r.Field<

 

string>("IONumber"),
IOName = r.Field<string>("IOName")
}

I am getting error on 'group' saying:
'Telerik.Web.UI.GridDynamicQueryable.GroupBy(System.Linq.IQueryable, string, string, params object[])' is inaccessible due to its protection level

Can anyone suggest how to update this query to work fine? (I am using telerik 2009)

 

 

 

 

 

 

Hi,
about this subject i have read some trhead in this forum but  could'nt find a solution for my problem.

Here the problem:
i manage the parameter by the build in Ui for parameter, My parameter is setted as multivalues.
Now i would like to get  the values  choosen by the user.

Documetation and intellisense, about ReportParameter.value property, says :
"Gets or sets the value of the parameter. Can be an Expression that evaluates to an object, value of the allowed types, or [!:IEnumerable] containing values of the allowed types. "

But ReportParameter.value  is an object and does'nt expose an enumerator. In same place i read it is an ArrayList so i tried something like that:

and i get the above error:
Unable to cast object of type 'System.Object[]' to type 'System.Collections.ArrayList'.

No matter what typ of collection i tried with( Ilist,List). I get always a casting error.

So i can retrieve the list of values of a multivalues parameter?

Thanks

I have a very simple report, that pulls from a sample database with no NULL values. I have the report working fine, and have added a parameter and a filter to filter by user name.

I would like the option of running the report for all names. I changed the "AllowNull" value to true. When I try to run the report, I get the following error:

An error has occurred while processing Report 'talksafe1':
Object cannot be cast from DBNull to other types

How do I run both filtered and unfiltered data? Again, I have no NULL values in my database, it only contains 4 records.

=Fields.Manager =  =Parameters.ManagerPrm.Value

AllowBlank = True
AllowNull = True
DataSource = SQLDatasource1
DisplayMember = Fields.Manager
ValueMember = Fields.Manager
Name = ManagerPrm
Text = Select Manager
Type = String
Visible = True

Hi everyone,

I am trying to make arithmetic operation with two fields from two different datasources in a textbox. One of the datasources (A) is datasource of the report and show the fields in the detail section. Another one (B) returns just one row.
In the footer section, I have to make addition with B and sum of A.

Any suggestions ?

How can i render new report, on a click command. Like a refresh button.

Which function in the Silverlight ReportViewer can be used to request new report, I was not able to find any render Function.

Hi,

I'm evaluating your reporting library with some test samples. One of these is a report with serveral charts and tables (in the pageFooter section there is a textbox with the PageNumber object). When I preview in reportviewer, the report is shown without paging, and the page number value is always 1 (even if the rendered report size has two or more pages). When exporting to pdf the number of pages is correct (and also the page number field in the footer section).

Is it possible to hide the PageNumber field when previewing with Reportviewer (and show it when export to pdf or print)? I've seen your Invoice Report sample works in this way, but I don't know how to get that.

How can I display the correct pages and its numbers when previewing in Reportviewer (like the Preview tab in design mode in VS)? Is it possible?

Regards,
John.
