DataGrid：同一列中的不同单元格类型 [英] DataGrid: Different Cell Types in Same Column

问题描述

我有一个ViewModel，其中包含以下属性（未显示任何与MVVM相关的代码）：

I have a ViewModel that has among others the following properties (not showing any MVVM related code):

class MyVM {

    string Name {get;组; }¥b $ b   类型类型{get;组; }¥b $ b    object Value {get;组; } b $ b}

class MyVM {
   string Name { get; set; }
   Type Type { get; set; }
   object Value { get; set; }
}

基本上，它就像"属性"一样。 Visual Studio中的窗口。我有名称或属性，它可以接受的类型（int，float，string或list）和实际值。我想在DataGrid中显示它们。 Value列应该基于Type属性创建
单元格，即如果类型为字符串则为文本字段，如果类型为int则仅接受int的文本字段等。我只看到类型更改为的解决方案整个列，但不是逐个单元格。我该怎么做？

Basically, it's like the "Properties" window in Visual Studio. I have the name or the property, the type it can accept (either int, float, string or list) and the actual value. I want to show those in a DataGrid. The Value column should create cells based on the Type property, i.e. a text field if the type is string, a text field only accepting int if the type is int, etc. I only see solutions where the type is changed for an entire column but not on a cell-by-cell basis. How do I do this?

喜欢hulamula，



>>"值"列应根据"类型"属性创建单元格，即文本字段（如果类型为字符串，文本）如果类型为int，则仅接受int的字段等。我只看到解决方案，其中类型
针对整个列而不是逐个单元地更改。我该怎么做？



在你的MVVM模式中，你可以为单元格创建一个ViewModel并绑定它作为ItemSource。在您的ViewModel中，您可以设置所需的元素。  



然后，您可以使用
CellTemplateSelector
根据类型和值值为其他列中的单元格选择模板。 



如需更详细，请参阅：

Hi hulamula,

>>The Value column should create cells based on the Type property, i.e. a text field if the type is string, a text field only accepting int if the type is int, etc. I only see solutions where the type is changed for an entire column but not on a cell-by-cell basis. How do I do this?

In your MVVM-Pattern, you can create a ViewModel for cells and bind it as ItemSource. In your ViewModel you can set the Elements that you need.  

Then, you can use the CellTemplateSelector to select a template for the cells in another column based on the Type and Value value. 

For more detailed, please see:
