Just today I tried opening up a report to make edits, and I get the titular error in Visual Studio: "Error HRESULT E_FAIL has been returned from a call to a COM component"

I've attached a screenshot.

After I got this error, I upgraded to the latest release. Note that I can still view reports in my MVC application, but I can't edit them with Visual Studio.

What has gone wrong, and how do I correct it?

Thanks,

Matt

I have to say, I really like what I see with Telerik Reporting.  The accuracy of the export to Excel and PDF is what has led me to look at it deeper and deeper.  However the Chart Object in the reports simply sucks.  When I was using the RadChart in a standard ASP.NET page I could easily get in and change individual bar colors during the ItemDatabound event.

I've spent a considerable amount of time searching the documentation for an example and reading through other posts, but haven't found what I'm looking for, so forgive me if this is covered somewhere already, I just haven't seen it.

I'm trying to implement my first ReportViewer, and I'm getting this error:

But I have this in my Web.Config:

Any ideas?

I am using a chart within a telerik report. I've gotten it mostly under control, however one issue remains. 

the X axis could have 10, or 500 items. Is there any way to limit how many data points are labeled?   By default, telerik displays every one, and it's just one big gray blob.. 

is there a way to just tell telerik to show 5 labels across x-axis ? this could be every other item, or every 1000th item. whatever is necessary to make it look nice and spaced. Do i have to perform calculus in my sql select to figure this out and set labels that way?  because that seems to be the only way out of this mess..  this has to be a common problem. 

Hello,
I need to know which version if telerik reporting viewer is build on WPF 2013.2.724.40

I need it since with 2013 I've got WPF visualization problem with a radgrid and need to hotfix downgrading to 724 but with 724 I have reference problem when using 7.2.14.127

Thanks

Hi,

I am using out proc session state in our application and have done all necessary changes mentioned in Design Considerations for Out-proc Session State.
But while populating reports, ItemDataBinding and ItemDataBound never get called even after these changes.
Is there anything I missed out or need to add?

Hi!

I have 2 Questions for which I haven´t found a sufficent answer elsewhere.

I´m using Telerik Reporting Q2 / 2012 for a Silverlight 4 project, so upgrading is not an option. (Or do the newer Report Versions still work with SL 4?)
The datasource I use is an object datasource.

1. The Datasource contains arrays and lists. In my Report I want to have a dynamic part for each item in the List. I Understand, that you can´t access elements of the list directly, but have to use a seperate datasource for the array. I tried that but the only datafield I see in there ist one item.
How can I implement a report with a dynamic part (f.e. a row in a table) that repeats for every element in the array, without having the need to design them all myself?

2. Trying to solve 1. I have made a binding to the visibility of a row to the number of elements in the array. The row wasn´t visible if the count was less than a specific number, but there was still a white space for it reserved in the report. How can I not only make a part of the report invisible, but also prevent that there is some space reserved for it?

Kind regards

I am working with 2013 Q3 reporting and VS2013 when I design a drill down report the expand/collapse does not work in preview, but works fine when published to the intranet.

Is it possible to use a 'Filtered' Telerik Grid as a datasource for a report.?
I have a grid that has numerous columns that can be filtered on. Once a use is done applying their filters, I want to pass the results to a report. Not just export the grid. I can design the Report using the same sproc that the grid uses so in theory I would be applying the filter inside the sproc and the report would be none the wiser, all the columns would be the same. So if I design the report initially using a SQLDataSource can I swap it out at run time with the results of the filtered grid?It would not be feasible to create report parameters for all the fields that can be filtered in the grid, I just want to leverage what the grid can already do.
