I would like to pass multiple parameters with my hyperlink to other page here is want i have in .aspx file
<Columns>
    <asp:BoundColumn HeaderText="Emp ID" DataField="EmpID"></asp:BoundColumn>
    <asp:TemplateColumn HeaderText = "Emp Name" >
<ItemTemplate>
    <asp:HyperLink  ID="Hyperlink1" Runat="server" NavigateUrl='<%# BuildUrlWithQueryString  ("Details.aspx", "EmpID", Container.DataItem("EmpID"), "EmpName", Container.DataItem("EmpName")) %>' />
</ItemTemplate>
</asp:TemplateColumn>

-- HERE IS THE BuildUrlWithQueryString  which i have put in code behind file this is working fine

Function BuildUrlWithQueryString(ByVal baseUrl As String, _
    ByVal ParamArray args() As String)
        Dim params As String = ""
        Dim i As Integer
        For i = 0 To args.Length - 1 Step 2
            ' if this is not the first parameter, concatenate with &
            If params.Length > 0 Then params &= "&"
            ' add the param_name=param_value piece to the current params string
            params &= HttpUtility.HtmlEncode(args(i)) & "=" & _
                HttpUtility.HtmlEncode(args(i + 1))
        Next
        ' add the params to the base url and return the final string
        Return baseUrl & "?" & params
    End Function

--I HAVE TESTED THE FUNCTION LIKE THIS IT SEEMS TO ME THAT THE FUNCTION IS WORKING BUT I DONT KNOW WHY THE HYPERLINK VALUE DOESNOT GET DISPLAYED
Label2.Text = BuildUrlWithQueryString("details.aspx", "EMPID", "111111111", "EmpName", "Dan")
 ---RESULT
details.aspx?EmpID=111111111&EmpName=Dan

--EmpId gets displayed on the web page but nothing gets displayed in the EmpName column

Thanks in advance

are you using asp.net 1 or asp.net 2.0, if you're using .net 2.0 one way is:
NavigateUrl=' <%# "Details.aspx?EmpID="+Container.DataItem("EmpID")+"&EmpName=" + Container.DataItem("EmpName")) %>'

well, let's look at your function,  are you sure you can compile your file with the function you posted?  Two things are missing, one is the function return type, the other is If not ended.
