datasource

问题 I've got a report running the data I want - from the Preview tab, that is, or when run using F5 in VS 2010. But when I upload the report (.rdl file) to SQL Server Reporting Services, and run the updated report from there, it still shows the old bunch of (restricted) data. Am I missing a step - does something need to be done other than uploading the .rdl file from the project?

问题 I have a FormView control with a custom PagerTemplate with my own paging LinkButtons. All works great until the dataset that I load only contains one record/item and hides the PagerTemplate completely. I've searched online and found several answers to simply add: protected void fvAppHMDA_PreRender(object sender, EventArgs e) { if (fvAppHMDA.TopPagerRow != null) fvAppHMDA.TopPagerRow.Visible = true; } However, this is not making one bit of difference. It seems that when there is only one

问题 I´m using a DetailsView but when updating, I cannot get the OldValues because the DetailsViewUpdateEventArgs.OldValues of ItemUpdating event is always empty. The NewValues has the values ok.
