Hi Mohammad,
Thank you for interesting in Syncfusion products.
We have checked your query “Is there a way to sufficiently export a GridDataBoundGrid(Classic) to a delimited text file” at our end. We regret to know that as per the implementation of GridDataBoundGrid don’t have the direct support to export the GridDataBoundGrid to text format file. However this can be achieved by copying the grid to the clipboard and then loading the data into a text file format. You can refer the following sample to achieve your scenario.
Please let us know if you would require any other assistance. we will be happy to assist you.
