Extend Hidden Row

Screen1.png (58.1 KB)

I have a workbook with grouped lines.
You can see a screen as an attachment.
How can I extend the hidden lines?

Thank you for your help


Thanks for using Aspose APIs.

It seems, you want to ungroup the grouped lines. In your screenshots, there are + buttons. Please press them and they should ungroup the hidden lines and change into - buttons.

I press the + buttons and nothing happens.

You can find a sample of our code in the link below


use DYN-W010 - Conso pack Mazars WEB_11.xls -> C5


Thanks for your sample project. We will look into this issue and help you asap.

This issue has been logged as

  • CELLSNET-45692 - GridWeb does not ungroup rows on clicking the + button

Here is the screenshot for a reference.


In order to render worksheet that has hidden rows and to enable the row/column group features, please set



<acw:GridWeb ID="GridWeb1" runat="server" XhtmlMode="True" Height="804px" Width="1119px" RenderHiddenRow="true" >


My RenderHiddenRow is already set to “true”.
This doesn’t work for me.

You try this option with our sample ?


Does your solution/project need Microsoft Visual Studio 2017? When I open it in VS 2015, project does not load.

However, product team has tested this issue and found, you must use latest acwmain.js and Aspose.Cells.GridWeb.dll. It will fix your issue.

Please download them from this link.
