在按下Enter键时单击按钮，而不是单击控件

Question

I'm trying to make a button called btnSubmit submit my customer's information if they hit enter on the keyboard. I know in VS2012 if I'm coding strictly C#, I can change the properties very easily and set up a button to be activated when enter is pressed.

Because I am coding in .net with C#, I do not have that option for my control. Any advice with coding? Can't find anything.

I am working with a web form.

Answer 1

I think this will do the trick.

Don't attempt to trigger a button click. Essentially what you should do is refactor your code so that the event handlers are separated from the actual implementation. eg

void Form_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        CheckAnswer();
    }
}

public void button1_Click(object sender, EventArgs e)
{
    CheckAnswer();
}

private void CheckAnswer()
{
    // do your stuffs on button click 
}

Answer 2

您应该将UseSubmitBehavior属性用于按钮控件，并将其设置为TRUE例如

UseSubmitBehavior="true"

Answer 3

Create a Panel and set its DefaultButton property with the name of the submit button. Every time you hit 'enter' in any TextBox inside the panel, it will call button's OnClick event. Like this:

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">

    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click"  />

</asp:Panel>
