Question

我目前正在创建一个带有数据视图的用户Web控件目前这是gridview

<div class="col-md-12">
        <asp:GridView id="dtgrid1" runat="server" AutoGenerateColumns="False"  AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" AutoGenerateSelectButton="True" CellPadding="4" ForeColor="#333333" GridLines="Horizontal" AllowPaging="True" width="100%" ShowFooter="True" ShowHeaderWhenEmpty="True" EmptyDataText="No records Found">
            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="ID" ItemStyle-Width="30" />
                <asp:BoundField DataField="Descripcion" HeaderText="Descripcion" ItemStyle-Width="250" />
                <asp:BoundField DataField="Monto" HeaderText="Monto" ItemStyle-Width="150" />
                <asp:BoundField DataField="Fecha" HeaderText="Fecha" ItemStyle-Width="150" />
            </Columns>
            <EditRowStyle BackColor="#999999" />
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
            <SortedAscendingCellStyle BackColor="#E9E7E2" />
            <SortedAscendingHeaderStyle BackColor="#506C8C" />
            <SortedDescendingCellStyle BackColor="#FFFDF8" />
            <SortedDescendingHeaderStyle BackColor="#6F8DAE" />
        </asp:GridView>
    </div>

gridview是一个webuser控件与其他cotrols和divs，everythings显示它应该但gridview 这是onload事件上的代码

If Not Page.IsPostBack Then
            dim dgv1datatable as new DataTable
            With dgv1datatable
                .Columns.Add(New DataColumn("ID", GetType(Integer)))
                .Columns.Add(New DataColumn("Descripcion", GetType(String)))
                .Columns.Add(New DataColumn("Monto", GetType(Double)))
                .Columns.Add(New DataColumn("Fecha", GetType(Date)))
            End With
            Session("dgv1dt") = dgv1datatable
            dtgrid1.DataSource = DirectCast(Session("dgv1dt"), DataTable)
            dtgrid1.DataBind()
            dtgrid1.Visible = True
        End If

但它现在显示了gridview，但是如果我把它放在gridview应该是gridview的地方，那么gridview会显示任何帮助吗？

EDIT 我将尝试更好地解释这个问题这是gridview应该在占位符中的webusercontrol中的位置因为它没有显示我决定删除占位符并将gridview放在同一个地方它确实出现了

Answer 1

<asp:SqlDataSource ID="SqlDataSource1" runat="server" CacheExpirationPolicy="Sliding" 
    ConnectionString="<%$ ConnectionStrings:catalog %>"     
        SelectCommand="SELECT * FROM YourDB"></asp:SqlDataSource>

占位符内的Gridview
