  Line breaks between dynamically generated labels

  May 02, 2012 02:00 PM|LINK

  Hi, I am trying to dynamically generate labels from a datatable. But they are all being displyed in one single line. How can I add a line break between them ? Here's my code. please let me know where I am going wrong?

  Dim lbl1 As New Label()
  LabelControls.Controls.Add(lbl1)
  LabelControls.Controls.Add(lbl1)
  If dtab.Rows.Count > 0 Then
  For i As Integer = 0 To dtab.Rows.Count - 1
  lbl1.Text = dtab.Rows(i)(1)
  Next
  LabelControls.Controls.Add(New LiteralControl("<br />"))
  End If

  Thanks

  Dim lbl1 As New Label()
  LabelControls.Controls.Add(lbl1)
  LabelControls.Controls.Add(lbl1)
  

  It looks like right here you are adding the labels back to back which will but them on the same row.

  Try this:

  Dim lbl1 As New Label()
   LabelControls.Controls.Add(lbl1)
   LabelControls.Controls.Add(New LiteralControl("<br />"))
   LabelControls.Controls.Add(lbl1)
   If dtab.Rows.Count > 0 Then
   For i As Integer = 0 To dtab.Rows.Count - 1
   lbl1.Text = dtab.Rows(i)(1)
   Next
   End If

  i've tried

  kedarrkulkarni

  try this

  Dim lbl1 As New Label()
  LabelControls.Controls.Add(lbl1)
  LabelControls.Controls.Add(lbl1)
  If dtab.Rows.Count > 0 Then
  For i As Integer = 0 To dtab.Rows.Count - 1
    lbl1.Text = dtab.Rows(i)(1) + "<br/>"
  Next
  LabelControls.Controls.Add(New LiteralControl("<br />"))
  End If

  hope this helps...

  the breaks are showing up but the same column is repeating for the number of rows that are present.

  For Eg: isntead of displaying Name, ID, CIty, State, Country

  its displaying Name, Name, Name, Name, Name but with line breaks

  thanks

  it does not have to do with line breaks.... does it worked fine before using my solution?

  if u r looking for displaying different column values of same row... then u might want to change this

  lbl1.Text = dtab.Rows(i)(1) + "<br/>"

  as

  lbl1.Text = dtab.Rows(1)(i) + "<br/>"

  i.e. display different columns values of first row... is it what u did ealrier?

  hope this helps...

  thank you for the reply kedarkulkarni.

  i am trying to get all values from one column. but different rows.

  earlier i was getting the values from the column all in a single row. to break them apart i used the literal control.

  the code you sent is breaking the column values, but why is only one value being repeated? I am trying to figure this out.

  Any help will be appreciated

  thanks

  I'm in a loop again!

  This

  lbl1.Text = lbl1.Text + dtab.Rows(i)(1) + "<br/>"

  is appending the labels everytime. So if i have to  display 5 labels for the first selection and 7 for the second,  so instead of displaying 7 labels on selection 2, I have total of 12 labels displayed.

  If i remove the lbl1.text+ dtab.... i can get just one of the labels to display?

  Please help!
