I am trying to access a printbutton inside my listview control on a 3.5 asp form.

What I am trying to accomplish is to call a java script which validates the checkboxes on the lsitview.

Where should I been creating this sub procedure?

How do i access the print button?


Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here

Dim myButtonPrintOut1 As Button = CType(ListView1.FindControl("printButton1"), Button)
 myButtonPrintOut1.Attributes.Add("onclick", "return checkboxChecked()")

 End Sub

you must add  onitemdatabound="ListView1_ItemDataBound" to listview1 control in aspx section and put that code in your vb section :

Protected Sub ListView1_ItemDataBound(sender As Object, e As ListViewItemEventArgs)
      If e.Item.ItemType = ListViewItemType.DataItem Then
            Dim myButtonPrintOut1 As Button = CType(e.item.FindControl("printButton1"), Button)            
            myButtonPrintOut1.Attributes.Add("onclick", "return checkboxChecked()")
      end if
End Sub

can you verifie aspx listview control is similar to this in aspx code ?:

<asp:ListView ID="ListView1" runat="server"
            OnItemDataBound="ListView1_ItemDataBound" DataKeyNames="something"
            DataSourceID="SqldatasourceXXX" >
            <ItemTemplate>              
               <tr style="background-color: #FFFBD6;color: #333333;">
                    <td>
                        <asp:Label ID="myID1" runat="server" Text='<%# Eval("something") %>' />
                    </td>
                    <td>
                        <asp:Label ID="myID2" runat="server" Text='<%# Eval("something_else") %>' />
                    </td>
                     <td>
                        <asp:button ID="printbutton1" runat="server" Text='PRINT' />                    </td>
                </tr>
            </ItemTemplate>
           
ensure that "ListView1_ItemDataBound" is fired by debugging and putting break-points in codebehind.
