Asp net razor pages application using ExportGridToPdf(GridParams g...)

Title:

BI{code} ?

I want to know how to determine in the razor code file the visible columns in the Grid. public IActionResult OnPostExportGridToPdf(GridParams g,....) returns an empty g.Columns property. I want to fill g.Columns with the grid columns and add code to process only the Visible columns for export.

  ok, here's a solution a bit meta/hackish, will get improved in future version; given our export to pdf demo ( https://demo.aspnetawesome.com/GridExportToExcelDemo ), use this `getFile` method instead function getFile(url) { var $form = $('<form method="post"/>').attr('action', url).appendTo('body'); // add request paramters (sorting, grouping, any parent parameters) var req = $('#@(grid)').data('api').getRequest(); var columns = $('#@(grid)').data('o').columns; for (var i = 0; i < columns.length; i++) { var col = columns[i]; if (!col.Hid) { $form.append("<input type='hidden' name='viscol' value='" + col.P + "'/>"); } } for (var i = 0; i < req.length; i++) { $form.append("<input type='hidden' name='" + req[i].name + "' value='" + req[i].value + "'/>"); } $form.append($('#allPages').clone()); $form.submit(); $form.remove(); } and add the `viscol` parameter to the action the form is posted to, in our demo this is: public ActionResult ExportGridToPdf(GridParams g, bool? allPages, string[] viscol) if not all columns have a `Bind` set you could use `col.I` for column id, which you can set ( `Column{ Id = "abc"` )

  • Thanks again for everything. the new code with viscol has worked great and I'm happy. The export coding is done. On to my next challenge. This is all very new to me so i'm sure I'll have another question soon.
