When You do an export (in PRO) and pass the url with some additional query string, for example: /server/url/exports/exportFile.aspx?something=value, then export script in grid passes malformed query string: /server/url/exports/exportFile.aspx?something=value?filename=. Script does not check if another query string variables are passed before.
Example:
$grid.pqGrid("exportCsv", { url: "/server/url/exports/exportFile.aspx?something=value", sheetName: "pqGrid sheet" });
Gives ajax request to:
/server/url/exports/exportFile.aspx?something=value?filename=....
And should:
/server/url/exports/exportFile.aspx?something=value&filename=....
