自定义DataGridView重复列
我通过从DataGridView继承创建了一个自定义Winforms控件。
自定义数据网格视图定义了它自己的列和映射。
然而，每当我将它从工具箱拖到表单的设计图面上时，表单都会为自定义控件中的每一列重新创建一个列控件（DataGridViewTextBoxColumn），这样我最终会得到双倍的列数。有
整个想法是控制已经“自我意识”，所以我不需要表格做任何事情。很明显，我忽略了一些简单的东西，但我的网络比Windows更多，没有什么能立刻成为原因。

不知道它在哪里阅读这些“要求”来自......但这是错误的。它们已存在于自定义控件中。我想也许可以做一些AccessModifiers，但似乎无法解决它。

答案 0 :(得分：3)
您似乎尚未在这些列中指定了列DataPropertyName。如果您已手动创建列并将DataSrouce分配给数据网格，则将自动生成不匹配的列。在MSDN
DataPropertyName的更多信息和示例
答案 1 :(得分：1)
转到 gridview 属性或F4 - ＆gt;取消选中自动生成的Coloumns =＆＃34; False＆＃34;
答案 2 :(得分：0)
如果你有这样的代码;
for (int i = 0; i < columnNames.Length; i++)
{
GridName.Columns.Add(columnNames[i], columnNames[i]);
}
只添加一列。我用了一面旗帜
if (AddColumnFlag)
{
for (int i = 0; i < columnNames.Length; i++)
{
GridName.Columns.Add(columnNames[i], columnNames[i]);
}
}
当我在除构造函数之外的任何地方调用函数时，将flag设置为false。 它解决了我的问题。
