[RESOLVED] Hiding the tr in asp.net

Good day all

i have a strange issue here.

i have a table row defined like this

Code:

---


                    <tr  id="tr6_3" runat="server" visible='<%# CheckVisible() %>' >
                        <td>
                        </td>
                        <td>
                            <strong>10.10 Introduction of a Project </strong>
                        </td>
                    </tr>

---

and the Function defined on that server is like this

Code:

---

Public Function CheckVisible() As Boolean
          Dim sqlcout As New StringBuilder()

        sqlcout.Append("select Count(*) as [COUNT]")
        sqlcout.Append(" from mytable")
        sqlcout.Append(" where fieldid= '" + fieldid+ "'")

        Dim drcount As DataRow = clsFunctions.returnaRow(sqlcout.ToString())
        Dim Results As Boolean
        If (drcount Is Nothing = False) Then
            If (drcount("COUNT") = 0) Then

                Results = False
            Else
                Results = True

            End If
        End If
        Return Results

    End Function

---

i have debuged this and it brings "0" but the Tr does not get hidden. i am i missing something here?

thanks

Hi.Having in mind that this will not work if you are calling it as a function somewhere,sometime inside your code,
add this on page load.

Code:

---

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Page.DataBind()
    End Sub

---

You can of course put that on, let's say a button click.
Although i am not fond of messing markup with server side code.

Thanks for your reply

i have resolved it by doing the Following

Code:

---

If (drcount Is Nothing = False) Then
            If (drcount("COUNT") = 0) Then

                Results = "display : none;"
            Else
                Results = "display : block;"
            End If
        End If

---

and

and on the markup i have something like this

HTML Code:

---

<tr style='<%= CheckVisible()%>'>

---

Hi.Since you have it run on the server you can change it whenever you want like this:

Code:

---

tr6_3.Style.Add("display", "none")

---

Yes
Thanks

No problem :wave:
