[ASP.NET]使用 DataGrid加入樣板控制項並繫結Javascript (Added template using the DataGrid control entry and tying Javascript)

使用 DataGrid加入樣板控制項並繫結Javascript



解決方法

---

在DataGrid裡加入一個樣版欄位, 裡面放了兩個linkButton主要是做"修改/刪除"功能的呈現

修改功能:導向另一頁面
刪除功能:彈出對話視窗,給使用者確認
DataGrid的是間繫結:ItemDataBound,ItemCommand

.aspx部分

<asp:DataGrid ID="dgData" runat="server" AllowSorting="True" AutoGenerateColumns="False" Width="100%" CellPadding="2">
 <ItemStyle Height="25px"></ItemStyle>
 <HeaderStyle HorizontalAlign="Center" ForeColor="White" BackColor="#006699"></HeaderStyle>
 <Columns>
  <asp:TemplateColumn HeaderText="功能">
   <ItemStyle Wrap="False" HorizontalAlign="Center"></ItemStyle>
   <ItemTemplate>
    <asp:LinkButton ID="lbEdit" runat="server" CommandName="Edit">修改</asp:LinkButton>
    <asp:Label ID="lblSeparate" runat="server">/</asp:Label>
    <asp:LinkButton ID="lbDelete" runat="server" CommandName="Delete">刪除</asp:LinkButton>
   </ItemTemplate>
  </asp:TemplateColumn>
  <asp:BoundColumn DataField="Model_status" HeaderText="目前狀態"></asp:BoundColumn>
  <asp:BoundColumn DataField="cr_date" HeaderText="建立日期" SortExpression="CR_date"></asp:BoundColumn>
 </Columns>
</asp:DataGrid>

.vb部分

Protected Sub dgData_ItemDataBound(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgData.ItemDataBound
 If e.Item.FindControl("lbEdit") IsNot Nothing Then
  Dim lbEdit As LinkButton = CType(e.Item.Cells(0).FindControl("lbEdit"), LinkButton)
  lbEdit.PostBackUrl = "myPag2.aspx"
 End If

 If e.Item.FindControl("lbDelete") IsNot Nothing Then
  Dim lbDelete As LinkButton = CType(e.Item.Cells(0).FindControl("lbDelete"), LinkButton)
  lbDelete.Attributes.Add("onclick", "return confirm('確認刪除否?');")
 End If
End Sub

Protected Sub dgData_ItemCommand(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgData.ItemCommand
 If e.CommandName = "Sort" Then'
 Exit Sub
 end if
 '以下寫應處理流程
 If e.CommandName = "Delete" Then'確認刪除後所進入的事件
 '做刪除的處理動作
 Exit Sub
 end if

End Sub
