我正在尝试在 ASP.NET 页面上创建一个动态 Gridview,我有多个行,并添加了一个 CheckBox 列。

<body>
<h1>Alerts</h1>
<form id="form1" runat="server">
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:KiwiLogConnectionString %>" SelectCommand="SELECT * FROM [Syslogd]
GROUP BY MsgHostname, MsgDate, MsgTime, MsgPriority, MsgText"></asp:SqlDataSource>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" DataSourceID="SqlDataSource1" ForeColor="#333333" AllowPaging="True" PageSize="15">
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:TemplateField >
<ItemTemplate >
<asp:CheckBox ID ="Checkbox" runat="server"/>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="MsgDate" HeaderText="Datum" SortExpression="MsgDate" ItemStyle-Wrap="false" >
<ItemStyle Wrap="False"></ItemStyle>
</asp:BoundField>
<asp:BoundField DataField="MsgTime" HeaderText="Tijd" SortExpression="MsgTime" ItemStyle-Wrap="false" >
<ItemStyle Wrap="False"></ItemStyle>
</asp:BoundField>
<asp:BoundField DataField="MsgPriority" HeaderText="Priority" SortExpression="MsgPriority" ItemStyle-Wrap="false" >
<ItemStyle Wrap="False"></ItemStyle>
</asp:BoundField>
<asp:BoundField DataField="MsgHostname" HeaderText="Hostname" SortExpression="MsgHostname" ItemStyle-Wrap="false" >
<ItemStyle Wrap="False"></ItemStyle>
</asp:BoundField>
<asp:BoundField DataField="MsgText" HeaderText="Message" SortExpression="MsgText" />
</Columns>
<EditRowStyle BackColor="#2461BF" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#EFF3FB" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#F5F7FB" />
<SortedAscendingHeaderStyle BackColor="#6D95E1" />
<SortedDescendingCellStyle BackColor="#E9EBEF" />
<SortedDescendingHeaderStyle BackColor="#4870BE" />
</asp:GridView>
<asp:Button ID="btn_update" runat="server" OnClick="btn_update_Click" Text="Update" />
</form>
</body>

如果选中该复选框并单击“更新”按钮,我希望隐藏这些行。我怎样才能做到这一点?

protected void btn_update_Click(object sender, EventArgs e)
{

}

gridview 是用 SQL 数据库构建的,所以它必须是动态的。在此,非常感谢!

最佳答案

您可以尝试以下方法:

protected void btn_update_Click(object sender, EventArgs e)
{
foreach (GridViewRow gvr in GridView1.Rows)
{
if (((CheckBox)gvr.findcontrol("Checkbox")).Checked == true)
{
//Do stuff with checked row
gvr.Visible = false;
}

}
}
