  replacing carriage returns in itemtemplate

  Feb 23, 2017 07:46 PM|Rusty1968|LINK

  I have a gridview that has one column that is populated from a multi-line textbox.  How can I replace the carriage returns with <br> so that I will see the line breaks in the grid?

  Here is the aspx code:

  <asp:TemplateField HeaderText="Corrective Action">
  <ItemTemplate>
  <asp:Label ID="lblCA" runat="server" Text='<%# Bind("Corrective_Action") %>' TextMode="MultiLine"></asp:Label>

  </ItemTemplate>

  I have tried in the rowdatabound event like this:

  If e.Row.RowType = DataControlRowType.DataRow And e.Row.RowState = DataControlRowState.Normal Then
  Dim lbl As Label = DirectCast(e.Row.FindControl("lblCA"), Label)
  Dim caText As String = lbl.Text
  caText = caText.Replace(vbCrLf, "<br>")
  lbl.Text = caText
  End If

  At some point this was working and running it in debug, it seems to work until I display the grid. I know I had this working but made changes to for some other requirements and it is probably something simple, so help!!

  Hi Rusty1968,

  According to your description, as far as I know, I think you want to realize text new line. after tested, your code is work. Here is my tested code, please check:

  Sample code:

  <asp:GridView ID="NewGrid" runat="server" OnRowDataBound="NewGrid_RowDataBound">
                  <Columns>
                      <asp:TemplateField HeaderText="Corrective Action">
                          <ItemTemplate>
                              <asp:Label ID="lblCA" runat="server" Text='<%# Bind("Corrective_Action") %>' TextMode="MultiLine"></asp:Label>
                          </ItemTemplate>
                      </asp:TemplateField>
                  </Columns>
  </asp:GridView>
  
  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
          Dim table As New DataTable()
          table.Columns.Add("Corrective_Action", GetType(String))
          table.Rows.Add("12" & vbCr & vbLf & vbCr & vbLf & "123" & vbCr & vbLf & "1")
          NewGrid.DataSource = table
          NewGrid.DataBind()
      End Sub
  
      Protected Sub NewGrid_RowDataBound(sender As Object, e As GridViewRowEventArgs)
          If e.Row.RowType = DataControlRowType.DataRow And e.Row.RowState = DataControlRowState.Normal Then
              Dim lbl As Label = DirectCast(e.Row.FindControl("lblCA"), Label)
              Dim caText As String = lbl.Text
              caText = caText.Replace(vbCr, "<br>")
              lbl.Text = caText
          End If
      End Sub

  Result:
