The data source property in the designer properties window is set to (none). I set this.DataSource = null; in the constructor after intiializecomponent. I have a dataset/dataadapter in the component window on the report, and in need data source, I do:
void SeekTeachFundsPerSiteStaff_NeedDataSource(object sender, EventArgs e)
this.DataSource = this.testDataSet.TestReport;
There is data that comes back; the key value comes from a drop down list. That drop down gets populated in the constructor. I select a value from the drop down, enter a start and end date, hit the preview button, and I get a valid resultset back. Event fires and all. I change the value in the drop down and hit preview again, and it fires the same resultset in triplicate (which I don't know how that happens). So it doesn't fire the second preview click; it doesn't recognize the value change...
So is this correct or incorrect? Also I tried using the table adapter as the datasource, but no luck either.
