ToolStripLabel

ToolStripLabel

• Jakein2006

  I'm coding in VB.NET so I use environment.newline and it is working.  However, I need a scrollbar and there is no scrollbar so now I'm playing with the TableLayoutPanel which does have a scrollbar.  However, I can't get the scrollbar to showup after i resume layout for the TableLayoutPanel.  Need help either with:

  a) use the ToolStrip and find a way to add a scrollbar or

  b)use the TableLayoutPanel and figure out how to get the scrollbar to show up.

  Any help you could offer for either direction (option a or b) would be GREAT!

  Here is my code for both(the code for the TableLayoutPanel is commented out):
  

  #Region "Declares"
  Private modobjarrSITHData() As dtcChangeRequest.SITHData
  #End Region

  Private Sub frmHelp_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
  Try
  ' get data
  modobjarrSITHData = DataConnections.SITH.RetrieveTopLevel()

  TableLayoutPanel1.SuspendLayout()

  ' add items to toolstrip
  Dim i As Integer
  Dim locintRecordCount As Integer = -1
  Dim locobjSITHItems(modobjarrSITHData.GetUpperBound(0)) As ToolStripLabel
  Dim locobjSITHItems2(modobjarrSITHData.GetUpperBound(0)) As LinkLabel
  Dim locstrSITHDescription As String = ""
  Dim locintDescriptionLength As Int32 = -1

  For i = 0 To modobjarrSITHData.GetUpperBound(0)

  locintRecordCount += 1
  locintDescriptionLength += modobjarrSITHData(locintRecordCount).SITHDescription.Length
  locobjSITHItems(locintRecordCount) = New ToolStripLabel
  'locobjSITHItems2(locintRecordCount) = New LinkLabel
  locobjSITHItems(locintRecordCount).Image = Bitmap.FromFile("C:\\Fantastapottumus\icons\help.gif")
  'locobjSITHItems2(locintRecordCount).ImageAlign = ContentAlignment.TopLeft
  locobjSITHItems(locintRecordCount).IsLink = True
  locobjSITHItems(locintRecordCount).DisplayStyle = ToolStripItemDisplayStyle.ImageAndText
  locobjSITHItems(locintRecordCount).Name = modobjarrSITHData(locintRecordCount).SITHID
  'locobjSITHItems2(locintRecordCount).Name = modobjarrSITHData(locintRecordCount).SITHID

  If locintDescriptionLength > 45 Then
  locstrSITHDescription = modobjarrSITHData(locintRecordCount).SITHDescription.Substring(0, 45) + Environment.NewLine + modobjarrSITHData(locintRecordCount).SITHDescription.Substring(46, locintDescriptionLength - 45)
  locobjSITHItems(locintRecordCount).Text = locstrSITHDescription
  Else
  locobjSITHItems(locintRecordCount).Text = modobjarrSITHData(locintRecordCount).SITHDescription
  End If

  'locobjSITHItems2(locintRecordCount).Text = modobjarrSITHData(locintRecordCount).SITHDescription

  'locobjSITHItems2(locintRecordCount).Anchor = AnchorStyles.Left Or AnchorStyles.Right

  'locobjSITHItems2(locintRecordCount).AutoSize = True

  'locobjSITHItems2(locintRecordCount).BorderStyle = BorderStyle.FixedSingle

  locintDescriptionLength = -1

  'FlowLayoutPanel1.Controls.Add(locobjSITHItems2(locintRecordCount))

  'TableLayoutPanel1.RowStyles.Add(New RowStyle(SizeType.AutoSize))

  'TableLayoutPanel1.Controls.Add(locobjSITHItems2(locintRecordCount), 0, locintRecordCount)

  Next

  TableLayoutPanel1.ResumeLayout()

  ToolStrip1.Items.AddRange(locobjSITHItems)

  Catch ex As Exception

  End Try

  End Sub

  A TableLayoutPanel is not a panel, it was designed to automatically move controls around when the form size changes. That's why it is so slow. Try a regular Panel. The scrollbar(s) automatically appear when you put a control beyond its bounds or set the AutoScrollMinSize property larger than the panel's size.

  A scrollbar in a toolstrip Why don't you simply use a Panel with its AutoScroll property set to True...

  Set the AutoSize property to False and edit the Size in the Properties window. Sadly, the control isn't smart enough to wrap the text itself. You need to help it by formatting the Text property with a line ending. For example:
  
  public partial class Form1 : Form {
  public Form1() {
  InitializeComponent();
  this.toolStripLabel1.AutoSize = false;
  this.toolStripLabel1.Size = new Size(60, 44);
  this.toolStripLabel1.Text = "Try a\r\nlong line";
  }
  }
  
  Note that you can't insert "\r\n" in the designer, you'll have to do it at run-time.

  With the ToolStripLabel I can use the DisplayStyle property to lign up an icon next to the text.

  I have tried using a panel, the TableLayoutPanel, and I have set the AutoScroll property to True and for some reason the scrollbar is not there. The code is above.

  I took care of the loading issue by suspending layout, creating the link labels, then resuming the layout - very speedy now.

  I did try the panel approach but it piled all of my LinlLabel controls on top of each other.

  The TableLayoutPanel is derived from the Panel control. It allows me to create a unique row for each LinkLabel I create. However, the scrollbar is not showing up. If I resize the form after runtime sometimes the scrollbar shows up...

  I have the solution. Here are the property settings for the TableLayoutPanel:

  Anchor = Left
  AutoSize = False
  AutoScroll = False
  AutoScrollMinSize=0,1000 ' the height will need to be adjusted based on how many records you think you will be returning.

  I edited the Columns collection - changed to AutoSize.
  Same for Rows collection.

  In the code behind I changed the AutoSize of each LinkLabel to False and then adjusted the height according to the length of the text. I also entered in a fixed width. The vertical scrollbar now appears due to the AutoScrollMinSize. I'll probably end up dynamically setting the AutoScrollMinSize based on how many records I return. (ie: 100 records returned multiply 1000*2 and so on).

  I also wanted to add an Icon (which is why I started with ToolStrip because of the nice DisplayStyle property). Easy fix, just add another column to TableLayoutPanel and set the image property to the bitmap.
