Add Rows/Columns to a Grid dynamically
提问by WAQ
I have a child UserControlcomprising of multiple textboxes, labels, image etc. I need to populate this user control in a Parent User control which has a Grid.
我有一个UserControl由多个文本框、标签、图像等组成的子项。我需要在具有网格的父用户控件中填充此用户控件。
The number of child user controls that need to be populated in the parent user control are determined at run time and can change. Basically the number depends on the search result. So it can be from 0 to n.
需要在父用户控件中填充的子用户控件的数量在运行时确定并且可以更改。基本上数量取决于搜索结果。所以它可以是从 0 到 n。
How can I populate my child user control in parent control? Or is there a better alternate to using a Grid control for this?
如何在父控件中填充我的子用户控件？或者是否有更好的替代方法来为此使用 Grid 控件？
Note: I have to do this in my ViewModel.
注意：我必须在我的 ViewModel 中执行此操作。

I'd prefer to go with an ItemsControl(Example). Use the ItemTemplateto link to your child UserControl's. If needed you can also tweak the ItemsPanelto control layout as you see fit.
我更喜欢使用ItemsControl( Example)。使用ItemTemplate链接到您孩子UserControl的 。如果需要，您还可以根据需要调整ItemsPanel以控制布局。
