c＃datagridview键处理

本文介绍了c＃datagridview键处理的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用DataGridView，在某些地方，我添加控制（例如textbox，combobox）

dataGridView1.Controls。添加（comboBox）; comboBox.Focus（）;问题是，使用这个控件，并且使用ENTER命令提交选项会导致DataGridView处理键 - >之后单击进入，而不是从组合框中选择sth，datagridview中的选择更改（移动到下一个单元格）。

我使用sth：

public class MyDataGridView：DataGridView { protected override bool ProcessCmdKey（ref Message msg，Keys keyData） { if（keyData == Keys.Enter） { return true; } return base.ProcessCmdKey（ref msg，keyData）; } }

但是它导致datagridview和combobox不回答到ENTER和其他键...

其他信息：我必须使用ComboBox类，而不是DataGridViewCombobox。

解决方案

尝试：

if（（keyData == Keys.Enter）&&（MyComboBox.Focused））

所以DataGridView响应ENTER，除非你的控件集中。

我不确定下面的代码是否适合你的情况，但也许你可以尝试类似：

public class MyDataGridView：DataGridView { public ComboBox MyComboBox {得到;组; } //如果你没有其他方法来引用它 protected override bool ProcessCmdKey（ref Message msg，Keys keyData） { if（（keyData == Keys .Enter）&&（MyComboBox.Focused）） { //提交选择逻辑 return true; } return base.ProcessCmdKey（ref msg，keyData）; } }

，如果需要，对您的ComboBox的引用：

dataGridView1.Controls.Add（comboBox）; dataGridView1.MyComboBox = comboBox; comboBox.Focus（）;

I use DataGridView, and in some places I add control to it (e.g. textbox, combobox)

dataGridView1.Controls.Add(comboBox); comboBox.Focus();

The problem is that using this control, and than commiting choice by using ENTER cause the DataGridView to "handle" the key -> after clickng enter instead of choosing sth from combobox, the selection in datagridview changes( moves to next cell).

I use sth like :

public class MyDataGridView:DataGridView { protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if(keyData == Keys.Enter) { return true; } return base.ProcessCmdKey(ref msg, keyData); } }

But it cause that datagridview and combobox doesn't answer to ENTER, and other keys...

Additional infromation: I must use ComboBox class, instead of DataGridViewCombobox. Can anyone help me how to handle ENTER in my comobox?

解决方案

Try:

if((keyData == Keys.Enter) && (MyComboBox.Focused))

so DataGridView responds to ENTER except when your control is focused.

I am not sure the following code fits your situation, but maybe you could try something like:

public class MyDataGridView:DataGridView { public ComboBox MyComboBox { get; set; } //in case you had no other way to refer to it protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if((keyData == Keys.Enter) && (MyComboBox.Focused)) { //commit choice logic return true; } return base.ProcessCmdKey(ref msg, keyData); } }

and from your form, if it needs, set the reference to your ComboBox:

dataGridView1.Controls.Add(comboBox); dataGridView1.MyComboBox = comboBox; comboBox.Focus();
