Q: RadDropDownTree as Parameter

[Michael]

I have a Web Application that populates various controls that are used as parameters, i.e., 3 RadDropDownTrees, 4 RadComboBoxes with check boxes, and RadComboBox without check boxes.
I know I can use the data sources that populate the combo boxes, but I do not know if I can use the datasources for the RadDropDownTrees.

My question is can a RadDropDownTree be used as a parameter in reportViewer? And if so, how?

Hello Michael,

Using the RadDropDownTree.OnentryAdded you can send the entered value to a report parameter using the report source object Parameters collection.

i hope this helps.

Thank you for your response. I may have to use your suggestion and pass in the parameters to the reportViewer.

My real question is can a ReportViewer contain a dataSource that is formatted to populate a TreeView or DropDownTree and use it in the parameter section of the reportViewer?

Hello Michael,

If you imply using ASP.NET DataSource components in Telerik Reporting, they are not supported.

We provide our own data source components. If you create a data access layer or other custom logic for data retrieval, we can recommend you to use Telerik Reporting ObjectDataSource component to wrap your data and use it as required in the report definition, e.g. for report's DataSource, items'  DataSource and parameter's AvailableValues.DataSource. The same business objects can be reused to create an ASP.NET ObjectDataSource for the TreeView/DropDownTree control.

If you need further help, please elaborate on the scenario, so we can provide you more accurate suggestions.
