It would be very handy, if the value property of the PictureBox would resolve images from base64 strings besides the Image, Image byte[], relative or absolute URI.
It should be fairly simple to implement. I wrote my own user function for this. It would be beneficial to have this out of the box.

[Function(Category = "Image", Namespace = "ImageFunctions", Description = "Converts a base64 string to an image byte array")]
public static byte[] ConvertFromBase64(string imageString)
{
    if (imageString != null)
    {
        // Convert base 64 string to byte[]
        byte[] imageBytes = Convert.FromBase64String(imageString);
        return imageBytes;
    }
    else
    {
        return null;
    }
}

It would be good if the table headers can be frozen.  This can  be really useful in case of a big report which is displayed on a single page.

When generating a report with multiple tables provide the ability to send these tables to different workbook tabs when exporting to Excel

Hello,

I have been working on some reports that require multiple tables on a single page. This limits the space columns have for data being bound to fit and results in text wrapping. I made a support ticket asking if there was a way to have dynamic column widths. I hoped to find a way to get table columns to change their widths depending on the data being bound to the table, while still maintaining the overall width of the table. My idea was to have it distribute the space (change the column width) to best display data and avoid text wrapping if possible. 

Attached to this request are some PDFs. One of them ("Current Report") shows that some data is either cut off or uses text wrapping. The other attached PDF shows the closest I could get to an acceptable layout, given our clients requirements and what our design team wants the reports to look like.

Thank you!

The Telerik Reporting only support fixed size page now.
But sometimes we need continues-roll paper mode.(like: receipt paper)

Some reporter tools: ActiveReports, it has 3 mode:(Page Reports,  RDL Reports,  Section Reports)

On "Telerik Forums / Reporting Forum" there is already some people asked it before 2 years ago. But until now the basic feature not release....

It would be great if you could introduce the ability to create custom reusable color palettes in Telerik Report Designer, so I don't have to declare the same set of colors for each chart I need them.

If you have a lot of graphs in your report then it is more convenient to change the color palette one place.

Asking to enable typing into the font combo box in standalone Telerik Report Designer.

The concept would be to click on the font drop down and just start to type the name of the font and have the list shift to that position for you.

We display data inside an HtmlTextBox that was entered using the RadEditor.  It would be great if the Reporting HtmlTextBox could be brought much closer or even in line with tag support as the editor.  We are frequently running into issues with uncommon tags (that we strip out for the HtmlTextBox) and also with spacing being different.  We work around the issues we have, but continuing increased tag support or auto stripping of unsupported tags would be very appreciated.

We create many legal forms, which use nested ordered lists. In htmlTextBox for reporting, we'd like to apply styles like upper-alpha, lower-alpha, etc to the ol tag. Currently, the only numbering for an ol is 1, 2, 3. CSS ability to set the style at depth (like ol ol) would be best.
<ol>
<li>1. text</li>
<li>2. text
  <ol>
  <li>a. text
     <ol>
          <li>i. text</li>
          <li>ii. text</li>
      </ol>
  </li>
  <li>b. text</li>
  </ol>
</li>
</ol>

If you do a Excel export, it renders the headers value, which we set with an expression (customer specific localised text), but as CSV the header names/IDs are used.
It would be nice to have a 'Export Settings' category on the page properties, see attachment for example. Also shows another useful feature of disabling export option easily per report.

Our clients enter information using the radeditor and in many cases want to embedded tables and graphics into their text.  Using your reporting tool there is no way to print this information.  I know you have suggested using your table and image tools, but that doesn't work when you are dealing with freely formatted text so the existance and location of the tables and images cannot be predicted.

To have a better performance would be nice to cancel report rendering automatically or manually. 
If I am asking for a big report and after I change parameters and request new report, the previous request is still in progress and it is not going to be cancelled. Therefore I see high memory consumption on continuously refreshing a reports with a big data and after some time I see complete slow down of the Reporting Service and of course slow down of the server itself. The memory in this case is not released and Reporting Service crashes sometimes.

Feature Request - Show email sent / error notification using the report viewers built-in notification system. 

It would be nice to have an option to have a message shown when the email with the report is sent or if there was an error sending.
Right now when you hit email and send the user does not know if it was successful or not. Being async is nice but I have noticed that it could take a few seconds to complete and if the user navigates away from the report viewer during this time the report has the possibility of not sending. Either way right now the user has no definitive method of knowing if the email was sent or not.

 

Reporting environment:                                                                                      

• UWP using the web viewer
• Odata web service to retrieve data (Web service data source)

The problem: I have a table that has several million records. I have a report with parameters to query those records. Example on a sales report: Customer (All or specific customer) and Product (All or specific product) and date range.  If by mistake the user selects all customers, all products, and a date range of 10 years, he may get millions of records for the report.  After several seconds he realizes that he entered the wrong parameters and wants to cancel the report.  There is no way to cancel. The solution was to run this in another thread and kill the process. That seems like a hack and doesn’t stop the web request so the web service keeps working even after the report has been killed.

Change request: Allow canceling in two ways:

1. The report viewer (we are using the web viewer) should have a cancel button
2. We should be able to cancel a report programmatically. 

The web data source should implement the “Cancellation Token” and cancel the web request when the report is canceled.  Postman, browsers, and other tools use this technique so that the web service understands that the data is no longer needed and it can stop the request.
