    Unhappy Filtering a datagridview on two fields

    I am hoping someone can help me. I am converting a Winform app to WPF. Sounded simple when my boss told me that's what I was going to do. But I have already ran into a problem. On the window below I have a DataGridview. The user selects a Category and the datagridview shows all the Campaigns for that Category. There are four types of entries Standard\Test\Control\Notes also Campaigns begin and end so the user only wants to see campaigns the were active for the date they enter. So what I need to do is figure out how to get the Datagridview to only show them what they want. I have included what code I have. I have read a lot about CollectionViewSource filtering but am fussy on how I apply it. I hope someone can help. Thanks

    Re: Filtering a datagridview on to fields

    For the record, the DataGridView is a WinForms control. You're using a DataGrid in a WPF app, so not the same thing. I thought you might have posted the right control name in the wrong forum but you actually posted the wrong control name in the right forum.

    I'm sorry the last thing I want to do is get someone else confused, I'm confused enough as it is. Is that because they removed the View source.

    DataGrid is the preferred name and WinForms does have a control with that name, released with the very first edition. It's a bit dodgy though and Microsoft realised that, so they created a new control that was released with .NET 2.0 and VS 2005. They could just replace the old control though, because there were plenty of apps already using it, so the new control had to be added alongside it with a different name. The documentation for the old DataGrid control is here. That's for .NET Framework 4.8. Everything had to be reimplemented for .NET Core and, as that page says, the DataGrid control was not included in that because it's not intended to be used in any new development.
