定义的DataGridView列类型编程 [英] Define DataGridView Column type Programmatically

问题描述

我需要一种方法中，我可以定义在运行时列类型

I need a way in which I can define the column type at run-time.

下面是我的代码：

foreach (DataGridViewColumn column in this.dataGrid.Columns)
{
???
//i.e. column.type  = checkbox
}

我怎么能在这个foreach循环定义列类型？

How can I define the column type in this foreach loop?

推荐答案

我不能肯定100％，我理解你的问题，但您可以指定，当您的列类型创建列：

I'm not 100% certain I understand you question, but you can specify the column type when you create the column:

foreach (var definition in columnDefinitions)  // Some list of what the column types are
{
    var columnSpec = new DataColumn
        {
            DataType = definition.Type, // This is of type System.Type
            ColumnName = defintion.Name // This is of type string
        };

    this.dataGrid.Columns.Add(columnSpec);
}

如果您需要更改类型一旦它被创造的 - 你不能去做。你能做的最好的就是删除列和新类型重新创建它们。

If you need to change the type once it's been created - you can't do that. The best you can do is delete the columns and recreate them with the new types.
