  CommandName of a datalist inside another datalist?

  Apr 08, 2012 06:40 AM|LINK

  Dear friends,

  I put a datalist inside another datalist. I works fine... But I couldn't call the CommandName of the inner datalist?

  I look forward to hear from you...

  Regards,

  I hope You mean CommandName of a Button in the child DataList.. am I right?

  First You have find out the Child DataList using FindControl method of the Parent DataList Then you have to find the Button using the FindControl method of the newly found out Child DtaList. Only then you can get the CommandName of the button.B

  Kindly mark this post as "Answer", if it helped you.

  Hi,

  Markup:

  <asp:DataList ID="DataList1" runat="server" DataKeyField="SehirID"
  Width="370px">
  <ItemTemplate>
  <table style="width: 100%;" bgcolor="#CCCCCC">
  <tr>
  <td class="style1">
  &nbsp;<asp:Label ID="LblSehir" runat="server" Text='<%# Eval("Sehir") %>'></asp:Label>
  </td>
  <td class="style2">
  &nbsp;
  <asp:LinkButton ID="LinkButton1" runat="server" CommandName="CmdSehirGuncelle">Güncelle</asp:LinkButton>
  </td>
  <td>
  &nbsp;
  <asp:LinkButton ID="LinkButton2" runat="server" CommandName="CmdSehirSil">Sil</asp:LinkButton>
  </td>
  </tr>
  </table>
  <asp:DataList ID="DataList2" runat="server" Width="292px"
  DataKeyField="MerkezID" style="float:right;">
  <ItemTemplate>
  <table style="width:100%;">
  <tr>
  <td class="style5">
  <asp:Label ID="LblMerkez" runat="server" Text='<%# Eval("Merkez") %>'></asp:Label>
  </td>
  <td class="style4">
  <asp:LinkButton ID="LinkButton3" runat="server" CommandName="CmdMerkezGuncelle">Güncelle</asp:LinkButton>
  </td>
  <td>
  <asp:LinkButton ID="LinkButton4" runat="server" CommandName="CmdMerkezSil">Sil</asp:LinkButton>
  </td>
  </tr>
  </table>
  </ItemTemplate>
  </asp:DataList>
  
  </ItemTemplate>
  </asp:DataList>

  Codebehind:

  Protected Sub DataList1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles DataList1.ItemCommand
  Dim myChildDataList As DataList = e.Item.FindControl("DataList2")
  If e.CommandName = "CmdSehirGuncelle" Then
  'Some codes goes here.
  ElseIf e.CommandName = "CmdMerkezGuncelle" Then
  'As you see this command name belogns to child DataList2 button

  'But it does not work.

  'Some codes goes here.

  End If
  End Sub

  
  Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles DataList1.ItemDataBound

  Dim mySehirID As Integer = DataList1.DataKeys.Item(e.Item.ItemIndex)
  Dim myMerkezDataList As DataList = e.Item.FindControl("DataList2")
  Sabitler.Public_DataListBagla(MyConn2, myMerkezDataList, "SELECT * FROM TblSehirlerMerkezler WHERE UstSehirID = " & mySehirID & " ORDER BY Merkez ASC")
  End Sub

  hi..

  i think it is so easy...see:

  protected void DataList2_ItemCommand(object source, DataListCommandEventArgs e)
      {
                 if (e.CommandName == "btn in ineer datalist commandName"){// do what you want}

                  }

  Hi,

  I tested it. Since it is childcontrol, it says "DataList2 is not declared".

  :(
