No Datasource in DataExplorer

[Gustavo]

I have a SqlDataSource that shows results, but not shown DataExplorer fields, the query is done through a stored procedure that contains dynamic SQL.

Hello Gustavo,

We evaluate expressions in runtime only thus in design time for DataSource parameter value we pass a null value. If your stored procedure doesn't return records when parameter values are null, we can't retrieve the schema. This is a known issue we have already fixed and we will introduce the fix with the next release.

In the meantime our suggestion is to check for null parameter values in the stored procedure and use default value or return some dummy data for the SqlDataSource to retrieve design time data schema.
