Tab不会触发keydown或keypress事件 [英] Tab will not fire keydown or keypress event

问题描述

我在一个网络表单中工作，并有一个带有标签栏的表单。每个标签都有多个文本框。我有选项卡索引增量，从每个选项卡的1开始。如果用户点击表单的末尾和击中选项卡，我想从选项卡到选项卡。

I am working in a webform and have a form with a tab bar on it. Each tab has multiple text boxes in it. I have the tab indexes incremented, starting with 1 for each tab. I want to tab from tab to tab if the user hits the end of the form and hits tab.

我使用leave方法并更改了标签控件的选项卡，唯一的问题是如果我没有打标签，并说我点击到该选项卡上的另一个控件仍将拍摄到新标签页。

I used the leave method and changed the tabs for my tab control the only problem is if I didn't hit tab and say I click to another control on that tab it will still shoot over to the new tab.

我想方法来解决这个问题是听tab键按下，如果按键是tab离开然后改变窗体的其他选项卡，我只是不能似乎得到它的工作，但。我已经尝试与按键和键下降，但都不会拿起那个标签作为键。

I figure a way to solve this would be to listen for the tab key press and if the key press is tab on leave then change the form to the other tab, I just can't seem to get it to work though. I have tried with keypress and keydown but neither will pick up that tab as a key. If I was to say click or hit start typing it will trigger the events but tab will not.

有任何建议吗？

我已经尝试过这些事件，甚至没有一个事件会触发。

I have tried these and none of these event would even trigger.

private void afsiTxtDaysForTempOEpriceOverrides_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == 11)
        {
            afsiTxtDaysForTempOEpriceOverrides_Leave(sender, e);
        }
    }

private void afsiTxtDaysForTempOEpriceOverrides_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == "11")
    {
        afsiTxtDaysForTempOEpriceOverrides_Leave(sender, e);
    }
}

private void afsiChkSalesBaseCostUpdate_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == 11)
    {
        afsiChkSalesBaseCostUpdate_Leave(sender, e);
    }
}

private void afsiChkSalesBaseCostUpdate_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == 11)
    {
        afsiChkSalesBaseCostUpdate_Leave(sender, e);
    }
}

编辑：发现页面使用UltraWinTabControl

Found out that the page is using UltraWinTabControl from Infragistics so maybe this is causing some issues with the tabbing.

推荐答案

我最终需要重写ProcessCmdKey现在我面对一个新的问题这是一种相关但不是特别的，所以我会添加它作为评论，如果我得到我的答案。

I ended up needing to override ProcessCmdKey now I face a new problem that is kind of related but not particular to this so I will add it as a comment if I get my answer.

    private bool isTab = false;
    private bool isShiftTab = false;

  protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {

        if (keyData == Keys.Tab)
        {
            isTab = true;
            ShiftTab.Append("Tab");
        }
        else
        {
            isTab = false;
        }

        return base.ProcessCmdKey(ref msg, keyData);
    }
