Cannot set parameter values from UI before viewing report.

Hi, this is a question about the default behavior of the report viewer.  When I programmatically set the parameter values in code, the report renders, and then I can change the parameters values on the UI inside the report viewer control.

Is it possible for me to load the report definition, and then, before the report renders, have the user set the parameter values within the report viewer control on the UI?  We have several scenarios where we want the user to enter parameters manually before the report is rendered.  I do not want to have to build additional controls to capture the parameter values when the report viewer already displays the parameters.

So far I am have not figured out a way to enter the parameters in the report viewer control, unless the report is already rendered.

Thank you.

Hi Ryan, 

Thanks for your interest in Syncfusion Components. 

If your requirement is to change parameters in the parameter UI before the report renders, then we suggest you not to set any default values to the parameter from code behind/report. If we have parameters without default value then a Parameter block has been shown to enter the values for the parameter before the report renders. We have prepared a simple sample based on this and it can be downloaded from the below location. 

Regards, 
Vinoth S.
