Export ASPxGridView with column with multiline text to excel - asp.net

Question

Is it possible to export ASPxGridView with column which contains multiline text to excel using ASPxGridViewExporter?
I have an ASPxGridView with column that contains a multiline text.
When I export a grid's data using ASPxGridViewExporter that multiline text is rendered as one line (without line breaks).
I tried both <br/> and "\n" (newline) as line separators.
btw value of property PropertiesTextEdit-EncodeHtml is false on that column.
Thanks

There are 2 ways to achieve what you're looking for:
Specify WYSIWYG export type in XlsxExportOptionsEx:
XlsxExportOptionsEx options = new XlsxExportOptionsEx()
{
ExportType = DevExpress.Export.ExportType.WYSIWYG
};
ASPxGridView1.ExportToXlsx("Test.xlsx", options);
Tell the exporter you want to have data aware export and handle CustomizeCell event to set cell wrapping to true:
XlsxExportOptionsEx options = new XlsxExportOptionsEx()
{
ExportType = DevExpress.Export.ExportType.DataAware
};
options.CustomizeCell += options_CustomizeCell;
void options_CustomizeCell(DevExpress.Export.CustomizeCellEventArgs e)
{
e.Formatting.Alignment = new XlCellAlignment() { WrapText = true };
e.Handled = true;
}
Then use the customized options object for export.
See: https://www.devexpress.com/Support/Center/Question/Details/T381176
There is also the RenderBrick event which sometimes may be helpful. You may handle it like:
gveExporter.RenderBrick += gveExporter_RenderBrick;
void gveExporter_RenderBrick(object sender, DevExpress.Web.ASPxGridViewExportRenderingEventArgs e)
{
...
StringFormat sFormat = new StringFormat(StringFormatFlags.NoWrap);
BrickStringFormat brickSFormat = new BrickStringFormat(sFormat);
e.BrickStyle.StringFormat = brickSFormat;
...
}
But I have not found how to actually force cell wrap there, because StringFormatFlags has only NoWrap among suitable items. In my experience I did have cell wrapping long text in the exported Excel doc, so I've used RenderBrick to switch that wrapping off.
Hope that helps.
