The button for REFRESH in crystalReportViewer does NOT work by default. How to make it work?

I am a rookie at C#, so please don`t be mad if my questions gonna sound stupid...

Hi Mitja,

I think that button redraws the report based on the current data source. If you're using a DataSet then it'll just use the same data. The refresh won't automatically go and get fresh data for the DataSet you've created.

It should work if the report itself contains a connection to the database and the query, rather than specifying the data source at runtime. Although I've never tried this myself.

So it is not possible to refresh the data in the report using DataSet?

I`m not a rookie anymore, but I`m still learning.

and one more thing, in my report I have a post number (its an integer from a database). Its written like (for example) 4.3432. It`s a dot after the 1st number. It shouldn`t be there. It should be 43432. I can`t get rid of that dot. Anyone knows how to get rid of?

Ok, I understand that refresh button can not refresh data which are previously entered into dataSet.

I suspect that the "." being displayed in your integer is caused by the number format. The default is to include the thousands separator. Right click on the field and select "Format Object" and change the style to something more suitable.

You can create a database connection and SQL query directly in the report, but I've never used it. I think it makes it difficult to target the report to different servers. Here we have development, test and live servers so we need to be able to get the report data from whatever server the application is currently using. Sorry, I can't be more help. I just know enough Crystal to get my reports done....

The CrystalReportViewer has a ReportRefresh event that fires before the report is refreshed. Maybe you can reload your DataSet there and it will update the data in the report.
