I have a dashboard in PowerBI that gets refreshed every day through our Data Gateway. I also have an Excel pointing to that dashboard. I'd like this Excel to be already refreshed when I open the Excel. This is why I'm doing a little C# program that does that for me after the Data Gateway refreshes the dashboard. But I'm unable to do this... Here's my code:
Excel.Application excelApp = new Excel.Application();
excelApp.DisplayAlerts = false;
Excel.workbook workbook;
// ...
workbook.RefreshAll(); // this doesn't refresh the connection
// ...
foreach(Excel.WorkbookConnection wc in workbook.Connections){
// I've also tried wc.OLEDBConnection.Reconnect()
// Also I've tried to manually enable refresh file on open and then from here just switch that off
// so when it opens it refreshes by default
wc.OLEDBConnection.Refresh()
}
// ...Through wc.OLEDBConnection I'm able to successfully access its properties (type, OLAP, RefreshDate,etc.) and add them to my logs, so I don't understand why it's not able to refresh it.
PD: this workbook.RefreshAll() code works for non-OLAP-connected spreadsheets.
Any help is appreciated!
