推荐答案

关于文本框的文本更改事件

On text change event of textbox

txtbox.text = StrConv(txtbox.Text, vbProperCase)

Private Sub TextBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
        TextBox1.Text = StrConv(TextBox1.Text, vbProperCase)
    End Sub

您可以使用以下javascript功能:

you can use following javascript function :

function initCap(str) {
    /* First letter as uppercase, rest lower */
    var str = str.substring(0, 1).toUpperCase() + str.substring(1, str.length).toLowerCase();
    document.getElementById('TextBox1').value = str;    
}

然后在文本框的 onblur 事件上调用该函数，如下所示:

and call that function on onblur event of text box as shown below :

<asp:TextBox ID="TextBox1" onblur="return initCap(this.value)" runat="server"></asp:TextBox>
