[RESOLVED] How to handle child datalist item command in a nested datalist

Hi,

I'd like to ask  a question,

I have this code below, and i want to make action if i press the button in the child datalist for example : open colorbox to view details of the record.

but, in fact .. 

this is the code:

                GridLines="Horizontal" BorderColor="#eeeeee">
                
                
                        






                        

                                
                                                                     ItemStyle-HorizontalAlign="Justify" DataSourceID="SqlDS_Crs">
                                    
                                    
                                        
                                        
                                        
                                 
                                       <%--                                          CommandArgument='<%# Eval("CID") %>' ImageUrl="images/request.gif" CommandName="details" />--%>


                                         
                                         
                                         

                              
               
                                 
                                
                                
                                                                    ConnectionString="<%$ ConnectionStrings:SMET_DBConnStr %>"
                                    SelectCommand="Admin_SP_GetCourses" SelectCommandType="StoredProcedure">
                                    
                                                                                    Type="Int32" />
                                    
                                
                                
                                
                
            

and this is what i did in the code behind:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        lbl_image.Text = "Training Packages"
        dl_Packages.DataSource = Admin.FN_GetPackages()
        dl_Packages.DataBind()
    End Sub

    Protected Sub dl_Packages_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dl_Packages.ItemCommand
        If e.CommandName = "details" Then
            Dim href As String = "'Request.aspx?CID=" & e.CommandArgument & "'"
            ClientScript.RegisterStartupScript(GetType(Page), "openColorbox", "openColorbox(" & href & ",630,450)", True)
        End If
    End Sub
    Protected Sub dl_Packages_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dl_Packages.ItemDataBound
        CType(e.Item.FindControl("lbl_PackageName"), Label).Text = DataBinder.Eval(e.Item.DataItem, "Package_Name_Ar")
        CType(e.Item.FindControl("lbl_PID"), Label).Text = DataBinder.Eval(e.Item.DataItem, "Package_ID")
        CType(e.Item.FindControl("lblIndex"), Label).Text = e.Item.ItemIndex + 1 & ". "

        '' Diaplay Courses ----------------------------------------------------------------------------

        Dim PID = CInt(CType(e.Item.FindControl("lbl_PID"), Label).Text)
        'CType(e.Item.FindControl("dl_Courses"), DataList).DataSource = Admin.FN_GetCourses(PID)
        'CType(e.Item.FindControl("dl_Courses"), DataList).DataBind()
       
    End Sub

the problem is, when i click on the linkbutton in datalist dl_courses, it is supposed to open anothe page in color box.

but in fact, nothing happens except the page is making refresh.

can anyone help me fixing this?

regards,

in the itemcreated event of d1_packages bind the d1_cource item command event with d1_packages item command. in that case only u will be able to finc the command of inner datalist

something like as below

Protected Sub Outer_ItemCreated(ByVal sender As Object, ByVal e As Web.UI.WebControls.DataListItemEventArgs) Handles Outer.ItemCreated

        If e.Item.ItemType = ListItemType.AlternatingItem OrElse e.Item.ItemType = ListItemType.Item Then

            Dim inner As datalist= DirectCast(e.Item.FindControl("inner"), datalist)

            AddHandler inner.ItemCommand, AddressOf inner_ItemCommand

        

        End If

    End Sub

then create inner_itemcommand method and place you command code there.
