Hi all,

Changing the name of the file with the following code:

<GridExcelExport FileName="@FileName" OnBeforeExport="@(()=> { FileName="test"; } )"/>

is not something that was intended to work (thus it worked by chance). The reason for this is that in order for the modified variable to be applied, a render cycle in the Blazor framework should happen while the "OnBeforeExport" event is happening, which is something that is not recommended.

Instead of making a "fix" for the workaround, we will probably consider exposing a "FileName" argument in the "OnBeforeExport" event, so that it can be overridden just like you can change the data or the columns.

This workaround no longer works. The filename remains the same as it was before the OnBeforeExport event is triggered. Just the same as changing the data and the columns seems pretty simple to expose the Filename attribute to allow the user to change the name. In my usecase, I have part of the name that needs to come back from the database as it calls the request to get that data (not same format as grid data). So I would need to call to get data in OnBeforeExport to get the part of the filename I need. Then move into setting the filename before the file is finally built.  OnAfterExport allows you to change and manipulate the file as well but does not allow you to update the filename either.

Hello Ted,

Indeed, the link was broken. Thank you for bringing this to our attention!

I have edited the Bug report description, and now the link should work correctly.

As of R2 2023, the default icon type will be SVG instead of Font. See this blogpost for more information.
