Hello,

I am fairly new to using Telerik Reports and was wondering if it is at all possible to use LINQ as a DataSource for these reports. My end goal is to call an IQueryable Function, while passing in a Username and Time Period to generate the Report for that User.


I have tried using SQL DataSources in my Reports, but would prefer to use LINQ if at all possible. Do Telerik Reports support the use of LINQ, or am I spinning my wheels on this one?

EDIT: Note, I am currently using what I believe is the newest version:
Telerik Reports: 2010.3 1110
RadControls for ASP.NET + AJAX:  2010.3 1109

Best Regards,

Landon

Hi,

we're still evaluating Telerik Reporting, especially the Silverlight components.

One problem we've found so far is, that it seems the image export does not obviously support transparent background colors.
Currently we tried the TIFF-Export using the Silverlight Report Viewer and the API of the rendering engine itself, both without luck.

What did we miss to get transparent background images (preferrably in PNG format) using the server side API ? Examples would be very appreciated ;)

Thank you so far and kind regards

The barcode throws an error if the data returned starts with a letter it works if the data starts with a number.  I am using Codabar symbology.  I have included a screenshot.

I'd like to find a simpler(and better) way of initializing an element.

Let me take an example of TextBox.
Because of Type conversion and etc. It is quite messy.

The following code is what I have as a solution. I used extension method.

Is Telerik going to provide something similar to this?

Hi,
   I am new to Telerik reporting. I have one report which has a text box control. I need to display this report for two text box values. I can hardcode these values but I don't know how to display a single report as two reports based on the value.

Textbox1.value = "ACTIVE COPY";
textbox1.value = "File Copy";

I want to display same report for these two values.

I appreciate your help.

Thanks
Raj

I am getting an error
"The name already exists in the tree: _10_035".
on one of my reports in the Silverlight Viewer only.
The report has Document Map and Bookmarks set.
This error does not come up with other reports or in the Designer Preview
Any tips as why this error would only come up in the silverlight viewer?

Hi,

    Is it possible to set the possition of a bar chart series Label based on the value of the bar.

    for example i have a bar chat that is used to display a percentage that can be posative or negative value. it is Horizontal and the 0 possition starts in the middle. so what i want to do is if the value is negative have the label on the right and if posative have the label on the left so it is not overlapping the bar.

Hello Telerik Team,

I have a requirement where I need to show a rad window on a telerik report.In this rad window I will have three paramaters with their own values.When the user selects a paramater and its value from the rad window ..how do you pass these values to the report.

I have the rad window working with combo boxes and i am storing the value from the rad combo box in a view state variable.I have added the report parameters programatically.But how do i pass these values to my report which consists of many formulae computed based on these parameter values.
I greatly appreciate your help.

Please provide me a sample report which has this functionality.

Thank You,
Smith

Hi,

I've got a master-detail report much like you're invoice example.
The subreport has a reportparameter which I then set to a field in the mainreport. So far so good.
But if I then add a filter to the mainreport the report doesn't work anymore, the parts in main are displayed correctly but in the subreport area I get a red text saying:

An error has occurred while processing Report ":
Method GetRowsByStringGuid(System.RuntimeType strGuid) not found.

I use entitydatasource as my datasource and the parameter is actually a guid so I have todo some manual conversion as guid's are not supported.

The strange thing I've noticed however is that if I specify a value for the parameter in the subreport in the ReportParameter Collection Editor like 0 which is not guid but still a valid string. The report works as expected again.

Is this by design or am I missing something or maybe I found a bug?

I'm looking forward to hearing from you.
