为动态按钮创建处理程序

我想为动态创建的按钮添加处理。最近的代码，我可以看到堆栈是：asp.net dynamically button with event handler 为动态按钮创建处理程序

我有代码，下面，创建一个按钮，但我想有一个处理程序为每个这些。

我迄今为止代码：

Dim control As LiteralControl 
     control = New LiteralControl("<div class=""bar-row"">" & _ 
            " <input value=""" & button & """ id=""" & id & """ class=""btnRisk"" type=""submit"">" & _ 
            " <div class=""bar-data"">" & _ 
            "  <div class=""bar-inner"">" & _ 
            "   <div class=""bar bar-high"" style=""width: " & highPer & "%"">" & high & "</div>" & _ 
            "   <div class=""bar bar-med"" style=""width: " & medPer & "%"">" & medium & "</div>" & _          
            "  </div>" & _ 
            " </div>" & _ 
            "</div>") 
     ChartArea.Controls.Add(control)

最重要的部分是：

" <input value=""" & button & """ id=""" & id & """ class=""btnRisk""  type=""submit"">"

我不知道如何修改这个。

我需要的按钮ID传递给发送者，然后做一些即

Public Sub Buttons(ByVal sender As Object, ByVal e As EventArgs) 

If sender = "1" Then 
'do something 
End If 
If sender ="2" Then 
'something else 
End If 
End Sub

VERSION 2

ChartArea.Controls.Add(New LiteralControl("<div class=""bar-row"">")) 

     Dim vRiskActive As String = "btnRisk " 
     If id <> "btnMech" Then vRiskActive = vRiskActive + " risk-inactive" 

     Dim btnButton As New Button() With {.Text = button, .ID = id, .CssClass = vRiskActive} 
     AddHandler btnButton.Click, AddressOf button ' here Buttons is your Handler 

     ChartArea.Controls.Add(btnButton) 

     If id = "ContentMain_btnMech" Then 
      ChartArea.Controls.Add(New LiteralControl(" <div class=""bar-data"">" & 
                "  <div class=""bar-inner"">" & 
                "   <div class=""bar bar-high"" style=""width: " & highPer & "%"">" & high & "</div>" & 
                "   <div class=""bar bar-med"" style=""width: " & medPer & "%"">" & medium & "</div>" & 
                 "   <div class=""bar bar-low"" style=""width: " & lowhPer & "%"">" & low & "</div>" & 
                "   <div class=""bar bar-na"" style=""width: " & naPer & "%"">" & na & "</div>" & 
     "  </div>" & 
                " </div>" & 
                "</div>")) 
     Else 
      ChartArea.Controls.Add(New LiteralControl(" <div class=""bar-data"">" & 
            "  <div class=""bar-inner bar-inactive"">" & 
            " </div>" & 
            " </div>" & 
                "</div>")) 
     End If

值得注意的副部...

Public Sub AddChartRow(ByVal button As String, ByVal id As String, ByVal high As Integer, ByVal medium As Integer, ByVal low As Integer, ByVal na As Integer)

参见[这个答案]（http://stackoverflow.com/a/389344/3740093）被找到如何访问的'

嗨@VisualVincent谢谢你。我有的问题是按钮是提交。我已将Dim n As String n = [String] .Format（“{0}”，Request.Form（“ContentMain_btnMech”））添加到我的页面加载中，但不要选择任何内容。 :-( – indofraiser

到目前为止我已经创建了它：但似乎没有点击（我已经添加了.aspx.vb oncommand代码） – indofraiser

我将建议更改您的HTML代码并创建一个按钮。同样在创建按钮后，您可以尝试为按钮的事件添加处理程序。约AdressOf操作

ChartArea.Controls.Add(New LiteralControl("<div class=""bar-row"">")) 

Dim btnButton As new Button() With { .Text = button, 
            .Id = id, 
            .CssClass = "btnRisk" 
            } 

AddHandler btnButton.Click, AddressOf ButtonsID ' here Buttons is your Handler   

ChartArea.Controls.Add(btnButton) 
ChartArea.Controls.Add(New LiteralControl(" <div class=""bar-data"">" & _ 
              "  <div class=""bar-inner"">" & _ 
              "   <div class=""bar bar-high"" style=""width: " & highPer & "%"">" & high & "</div>" & _ 
              "   <div class=""bar bar-med"" style=""width: " & medPer & "%"">" & medium & "</div>" & _          
              "  </div>" & _ 
              " </div>" & _ 
              "</div>")) 
       ChartArea.Controls.Add(control)

它说“价值不是按钮的成员” – indofraiser

对不起，显然VB Button中没有这样的属性，请尝试.Text属性。我编辑了一个答案。 – Mitrucho

谢谢，只是确保。有时它是提问者:-) – indofraiser
