如何将DataGridViewCell转换为控件 [英] How to convert a DataGridViewCell to a Control

问题描述

我正在尝试将DataGridView单元格转换为控件：

I am trying to convert a DataGridView cell to a control:

Control dat = new Control();
dat = Convert.ChangeType(dataGridView1[colIndex,rowIndex], typeof(Control));

我正在从索引代码中获取colIndex和rowIndes的值。问题是即使我尝试了许多代码转换，也无法正常工作。

I am fetching the values of colIndex and rowIndes from a index code. The problem is even though I tried many codes to convert, it does not work.

我得到的异常是：

不能隐式地将对象转换为控件。存在显式转换（是否缺少转换？）

Can not implicitly convert an object to a control. An explicit convertion exist(are u missing a cast?)

推荐答案

由 DataGridViewCell 托管，您使用当单元格处于编辑模式时，单元格的 EditingControl 属性。

此属性返回 System.Windows.Forms.Control 。

您也可以在 DataGridViewEditingControlShowing 事件中获得控件-的 Control 属性DataGridViewEditingControlShowingEventArgs 的类型为 System.Windows.Forms.Control 。

You can also get at the control within the DataGridViewEditingControlShowing event - the Control property of DataGridViewEditingControlShowingEventArgs is of type System.Windows.Forms.Control.

private void dataGridView1_EditingControlShowing(object sender, 
    DataGridViewEditingControlShowingEventArgs e)
{
    Control c = e.Control;
}

如果您想在其他时间访问控件，那么（我相信）您很不走运-我说这主要是基于 DataGridViewEditingControlShowing ：

If you want to access the control at other times then (I believe) you are out of luck - I say that based mainly on this quote from the MSDN docs on DataGridViewEditingControlShowing:

DataGridView控件一次托管一个编辑控件，并且只要单元格类型在两次编辑之间不更改
时，
就会重新使用该编辑控件。

The DataGridView control hosts one editing control at a time, and reuses the editing control whenever the cell type does not change between edits.
