  Re: how to get value from dynamic created text box

  Apr 04, 2012 03:29 PM|LINK

  For i = 0 To MeCount - 1
  id = ds.Tables(0).Rows(i).Item(0)
  Response.Write(id)
  Dim LastTextBoxId As String = " Txt-" & id
  id2 = "ctl00_InnerContent_" & ds.Tables(0).Rows(i).Item(0)
  Content = Request.Form("id2")

  above code is returning only id not the text inside the text box

  i m getting only ID

  but in request .form we hav to pass id or the name???

  Try to remove the If Not Postback check from the page load event:

  MultiView1.SetActiveView(View1)
  
  Dim PageNam As String = Request.QueryString("PageName")
  PageId.Value = PageNam
  Dim ds As DataSet = GetInspired.GetPageContent(PageNam)
  ' Dim ds As DataSet = GetInspired.GetPageContent("Default")
  Dim MeCount As Integer = ds.Tables(0).Rows.Count()
  Response.Write(MeCount)
  
  For i = 0 To MeCount - 1
  Dim myLabel = New Label
  myLabel.ID = "lbl" & i + 1
  myLabel.Text = "Content For " & ds.Tables(0).Rows(i).Item(2)
  myLabel.CssClass = "lbl_sec"
  Dim myTextBox = New TextBox
  myTextBox.ID = ds.Tables(0).Rows(i).Item(0)
  
  Dim LastTextBoxId As String = myTextBox.ID
  myTextBox.CssClass = "Text_Sec"
  myTextBox.TextMode = TextBoxMode.MultiLine
  PageContentSection.Controls.Add(HtmlHelper.GetLiteral("<div id=Txt-" & LastTextBoxId & " >"))
  Me.PageContentSection.Controls.Add(myLabel)
  Me.PageContentSection.Controls.Add(myTextBox)
  myTextBox.Text = ds.Tables(0).Rows(i).Item(3)
  PageContentSection.Controls.Add(HtmlHelper.GetLiteral("</div>"))
  Next
  End Sub

  Yes, but you need to re-create the textboxes on every postback.

  When using FindControl, you have to use the server side id:

  Dim TempTextBox As TextBox = CType(TextBoxControlPlaceHolder.FindControl(id.ToString()), TextBox)
