ثبت داده درListView، GridView بدون استفاده از DataBase در Asp.Net
دوشنبه 6 مهر 1394در این مقاله قصد داریم در مورد نحوه ی ثبت داده با استفاده از ListView و GridView و صفحه بندی کردن آن ها بدون استفاده از هر نوع دیتابیس را آموزش دهیم.
قدم اول:یک پروژه ی جدید را باز کنید.
قدم دوم :روی پروژه ی جدید راست کلیک کرده، و گزینه ی Add New Item را انتخاب کنید ویک صفحه ی Webform جدید را بسازید.یک ListView و یک GridView را اضافه می کنید.
داخل صفحه ی DesignUI قطعه کد زیر را می نویسید:
<body>
<form id="form1" runat="server">
<div>
<div style="width: 50%">
<div>
<h3>ListView</h3>
<asp:ListView ID="lvCustomers" runat="server" GroupPlaceholderID="groupPlaceHolder1"
ItemPlaceholderID="itemPlaceHolder1" OnPagePropertiesChanging="OnPagePropertiesChanging">
<LayoutTemplate>
<table border="1">
<tr>
<th>Product
</th>
<th>Quantity
</th>
<th>Price
</th>
</tr>
<asp:PlaceHolder runat="server" ID="groupPlaceHolder1"></asp:PlaceHolder>
<tr>
<td colspan="3">
<asp:DataPager ID="DataPager1" runat="server" PagedControlID="lvCustomers" PageSize="2">
<Fields>

</Fields>
</asp:DataPager>
</td>
</tr>
</table>
</LayoutTemplate>
<GroupTemplate>

<br />
<h3>FormView</h3>
<div>

<td class="ProductPropertyValue"><%# Eval("Price")%>
</td>
</tr>

<hr />
</ItemTemplate>
</asp:FormView>
</div>
</div>
<div style="width: 50%">
<h3>DetailsView</h3>
<div>
<div>
<asp:DetailsView ID="DetailsView1" OnPageIndexChanging="DetailsView1_PageIndexChanging" BackColor="Wheat"
