For the purpose of this tutorial, I have created two methods in custom business object.

The first method returns a Data Set object filled with Categories to display in Drop Down List control for user selection and the second method returns records from the Products table which are matching with the category user has selected from the Drop Down List control.

not when you have a dataset with 50 tables in it with relations on them….

The solution lies in the Get Errors method of the Data Table class: System Data Data Table Class Get Errors Essentially, when I see the message above, I check the Has Errors property for each Data Table in the data set and then invoke the Get Errors method on the tables reporting errors.

We made over 1,700 improvements and still have some work to do, but if you are using Visual Studio 2017 in a low-vision or no-vision mode, a lot has improved. NET Core as well as the tools for building, debugging and running . NET Core SDK, while also developing with the latest public releases. We’ve made strides in decreased memory usage, better performance, and decreased crashes.

Dante has a blog post on everything we’ve done and what’s more to come, but here I’ll call out a couple of the more major things we’ve improved. NET Core and this release focuses on performance improvements and expanding the set of APIs available via . Many of these fixes have been made possibly by your feedback, so please keep that coming through the Developer Community. For issues, let us know via the Report a Problem tool in Visual Studio.

Even when you cycle through rows in error, there’s nothing to point back to the original row index or field values???

I hope you have basic idea how to call methods by passing input parameters to them by using Object Data Source control.

The second Object Data Source control is configured to call Get Products By Category method from the business object but as you noticed in the method implementation above, this method accept one input parameter of int type and to pass this input parameter value we need to use Select Parameters collection of Object Data Source control as shown below In Select Parameters collection I am using Control Parameter which is setup to get the value of the input parameter from the Drop Down List automatically by using its Selected Value property.
