2. Add this sub to your page:


Public Sub DefaultButton(ByRef Page As System.Web.UI.Page, ByRef objTextControl As TextBox, ByRef objDefaultButton As Button)

' Sets default buttons.

' Created by Janus Kamp Hansen - http://www.kamp-hansen.dk

Dim sScript As New System.Text.StringBuilder()



sScript.Append("<SCRIPT language=""javascript"">" & vbCrLf)

sScript.Append("function fnTrapKD(btn){" & vbCrLf)

sScript.Append(" if (document.all){" & vbCrLf)

sScript.Append(" if (event.keyCode == 13)" & vbCrLf)

sScript.Append(" { " & vbCrLf)

sScript.Append(" event.returnValue=false;" & vbCrLf)

sScript.Append(" event.cancel = true;" & vbCrLf)

sScript.Append(" btn.click();" & vbCrLf)

sScript.Append(" } " & vbCrLf)

sScript.Append(" } " & vbCrLf)

sScript.Append("}" & vbCrLf)

sScript.Append("</SCRIPT>" & vbCrLf)



objTextControl.Attributes.Add("onkeydown", "fnTrapKD(document.all." & objDefaultButton.ClientID & ")")

Page.RegisterStartupScript("ForceDefaultToScript", sScript.ToString)

End Sub




Then call the sub in your page load with:


' Causes [Enter] key to "press" cmdButton when txtBox has focus

' The 'Me' should be what page you are dealing with. You can use 'Me'

' unless you are dealing with includes, .ascx files, etc.

    • 在Page_Load里写 button.select应该行吧 -vega_lee(天津の包子.NET); 2004-2-2 (#1587361@0)
      • 不行。没有button.select，应该和accesskey有关。 -goldsky(泥锅泥碗泥滚蛋); 2004-2-2 (#1587368@0)
        • 有点糊涂， 你是不是说你按enter的时候， 相当于click那个button？偶很菜的。 -henhen(哼哼，生日快乐！); 2004-2-2 (#1587373@0)
          • 是这意思，偶也很菜呀 -goldsky(泥锅泥碗泥滚蛋); 2004-2-2 (#1587379@0)
    • You need to create a function and call it from in page_load or wherever you want: -wjiaca(WSY); 2004-2-2 {226} (#1587371@0)
      private void setFocus( System.Web.UI.Control ctrl )
      {
      string s = "<SCRIPT language='javascript'>document.getElementById('" + ctrl.ID + "').focus() </SCRIPT>";
      this.RegisterStartupScript( "focus", s );
      }
      • 也就时说，vb.net不行，一定要用javascript? -goldsky(泥锅泥碗泥滚蛋); 2004-2-2 (#1587378@0)
        • right in web application -wjiaca(WSY); 2004-2-2 (#1587380@0)
          • 谢谢 -goldsky(泥锅泥碗泥滚蛋); 2004-2-2 (#1587384@0)
      • I think this focus will be lost after you input anything in the textbox. -hillxie(我叫不紧张); 2004-2-2 (#1587389@0)
        • 不紧张，你说对了，我怎么解决？忘赐教:) -goldsky(泥锅泥碗泥滚蛋); 2004-2-2 (#1587403@0)
          • So far I have no better idea than my another post, maybe somebody else will have one. -hillxie(我叫不紧张); 2004-2-2 (#1587416@0)
        • you're right, if you want a button to become default button after entering something on the page, you have to do something else. -wjiaca(WSY); 2004-2-2 (#1587408@0)
    • Make this button the first button in the form -hillxie(我叫不紧张); 2004-2-2 (#1587381@0)
      • it works. any other idea? -henhen(哼哼，生日快乐！); 2004-2-2 (#1587443@0)
