Trelerik Report Designer version is - 10.2.16.1025

https://www.telerik.com/support/whats-new/reporting/release-history/telerik-reporting-r3-2016-sp1-(version-10-2-16-1025)

See sample report content below as proof of concept for the error we are encountering. Follow these steps:

1) Go to Preview

2) Try export to Powerpoint Presentation

3) Encounter exception when exporting to .pptx - seems like the Angle=270 attribute on the textbox is the culprit. This was working in Telerik Reporting 10.1.16.615.

Report content:

<?xml version="1.0" encoding="utf-8"?>
<Report Width="16cm" Name="Report1" SnapGridSize="0.1cm" xmlns="http://schemas.telerik.com/reporting/2012/4.1">

    <PageHeaderSection Height="2cm" Name="pageHeaderSection1" />
    <DetailSection Height="5cm" Name="detailSection1">
      <Items>
        <TextBox Width="3.00000010093053cm" Height="1.99999939441683cm" Left="6.49999954581262cm" Top="2.19999989906947cm" Value="textBox1" Angle="270" Name="textBox1">

Hello Thomas,

Indeed, there was a problem when trying to render an item with angle set to, for example, 270 to .pptx format.
However, the issue has been already fixed in R1 2018 version 12.0.18.117. You can check the Release history for a reference. In order to export the report correctly, you would need to upgrade to the newer version of the product.

Regards,
Silviya
