C＃：ComboBox Enter to Tab [英] C#: ComboBox Enter to Tab

问题描述

我有一个带有添加项目的组合框，一旦按下comboBox中的enter，它应该转到下一个标签索引。我使用下面的代码用于textBox并且它正常工作，但是对于comboBox不工作，请指教。

Hi,

I have a combobox with added items, once I press the enter in the comboBox, it should go to the next tab index. I have using below code for the textBox and it's working, but for the comboBox not working, please advise.

private void textBox9_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == (char)Keys.Enter)
    {
        SendKeys.Send("{TAB}");
    }
}

推荐答案

使用 SendKeys 的UI开发是一件很脏的事情。所有你真的需要它来阅读适当的关注帮助。请参阅：

http：// msdn .microsoft.com / zh-cn / library / system.windows.forms.control.getnextcontrol.aspx [ ^ ]。



此外，请注意修改表格和控件的默认行为。







如果可以是这样的：

Using SendKeys of UI development is a dirty thing. All you really need it to read help with proper attention. Please see:
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.getnextcontrol.aspx[^].

Besides, be careful with modification of default behavior of forms and controls.



If can be something like:

Panel parent = //... // parent panel, form.., the parent of the controls to be focused
Form form = //... // the form containing controls in question

//...

// focus forward:
Control next = parent.GetNextControl(form.ActiveControl, true);
next.Focus();

尝试使用这个

try using this

private void comboBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                textBox1.Focus();//your control to focus
            }
        }

我尝试了同样的方法，它也适用于组合框。请检查是否有任何其他事件阻止此事件发生。

Hi,

I tried the same and it works fine with combo box also. Please check if there is any other event which stops this event from raising.
