Reportviewer parameters disabled dating, report parameters in local mode
In local mode the host application must handle parameter prompting, as seen in the example below. We know the code is called because we put some debugging output to make sure. Note that this textbox, checkbox, the url dropdown and the load button are all implemented by the host application. Report parameters can be used for other purposes too.
After further investigation, we isolated the problem further. Object, ByVal e As System.
Any ideas what could be wrong? Using report parameters in local mode What are report parameters used for?

But unlike the Report Server, best podcast dating the ReportViewer control does not execute queries itself.
Report parameters in local mode
The ability to turn descriptions on or off, and the ability to filter news items are implemented using report parameters. Everything works fine in our development environment. It's just the code that should cause certain parameters to show up again doesn't work.
Rather, queries are executed by the host application, and the result is passed to the ReportViewer control. The code to hide parameters is working fine.
The most common use of report parameters is to specify a criterion for subsetting data. Depending on a certain parameter of the report, we only need to have the user prompted for a subset of the rest of the report parameters. The value of the parameter may be set programmatically by the host application, or one report may pass a parameter to another report. Value where Foo is the name of the parameter.

Not only does it not show up the parameter prompts, but the Visible property of the parameter does not get set to true checked by using ReportViewer.
