人气:0想了解GridView自定义删除操作的具体方法的相关内容吗，在本文为您仔细讲解GridView自定义删除操作的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：GridView,自定义,删除，下面大家一起来学习吧。
首先，我们前端的代码如下：
复制代码 代码如下:
<asp:GridView ID="gridViewDxjk" CssClass="gridview" runat="server" AllowPaging="True"
DataKeyNames="P_ID" AutoGenerateColumns="False"
RowStyle-HorizontalAlign="Center" BorderWidth="1px" PageSize="17"
onrowdeleting="gridViewDxjk_RowDeleting"
OnRowDataBound="gridViewDxjk_RowDataBound"
onpageindexchanging="gridViewDxjk_PageIndexChanging" >
<HeaderStyle CssClass="head" />
<PagerStyle CssClass="pager" />
<RowStyle CssClass="row" />
<EditRowStyle CssClass="editrow" />
<AlternatingRowStyle CssClass="altrow" />
<EmptyDataRowStyle CssClass="empty" />
<Columns>
<asp:HyperLinkField HeaderText="编辑" ControlStyle-Width="50" DataNavigateUrlFields="P_ID" DataNavigateUrlFormatString="smsModify.aspx?id={0}" Text="编辑" >
<ControlStyle Width="50px"></ControlStyle></asp:HyperLinkField>
<asp:CommandField ShowDeleteButton="true" DeleteText="删除" >
<ControlStyle Width="50px"></ControlStyle></asp:CommandField>
<asp:BoundField DataField="P_ID" HeaderText="id" SortExpression="P_ID" ItemStyle-HorizontalAlign="Center" Visible="False" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_NAME" HeaderText="名称" SortExpression="P_NAME" />
<asp:BoundField DataField="P_Type" HeaderText="通知方式" SortExpression="P_Type" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_Fzr" HeaderText="姓名" SortExpression="P_Fzr" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_tel" HeaderText="通知手机" SortExpression="P_tel" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_jg" HeaderText="通知间隔(小时)" SortExpression="P_jg" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_on" HeaderText="是否开启" SortExpression="P_on" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_lasttime" HeaderText="最后发送时间" SortExpression="P_lasttime" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
<asp:BoundField DataField="P_memo" HeaderText="备注" SortExpression="P_memo" ItemStyle-HorizontalAlign="Center" >
<ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
</Columns>
<EmptyDataTemplate>
没有数据！
</EmptyDataTemplate>
<PagerTemplate>
<table width="100%" class="gvPage" style="font-size:12px;">
<tr>
<td style="text-align: right">
第<asp:Label ID="lblPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'></asp:Label>页
/共<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount %>'></asp:Label>页
<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
<asp:TextBox ID="txtNewPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' Width="20px" AutoPostBack="true" ></asp:TextBox>
<asp:LinkButton ID="btnGoEx" runat="server" CommandArgument="GO" CommandName="Page" Text="GO" OnClick="btnGoEx_Click"></asp:LinkButton>
</td>
</tr>
</table>
</PagerTemplate>
</asp:GridView>
后端的话，由于需要弹出删除前的确认框，所以，我们需要在RowDataBound里面做点什么？同时，要想真正的删除，还需要触发RowDeleting事件，具体代码如下：
复制代码 代码如下:
//报警删除
protected void gridViewDxjk_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string key = gridViewDxjk.DataKeys[e.RowIndex].Value.ToString();
bool flag = bll.Delete(Int32.Parse(key));
if (flag)
NXT_WLService.App_Code.JScript.Alert("删除成功！", this);
else
NXT_WLService.App_Code.JScript.Alert("删除失败！", this);
}
protected void gridViewDxjk_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton btn = (LinkButton)e.Row.Cells[1].Controls[0];
if (btn.Text.Equals("删除"))//刪除鈕才加提示訊息
btn.OnClientClick = "if (confirm('你确认要删除?')) javascript:__doPostBack('gridViewDxjk','Delete$" + e.Row.RowIndex.ToString() + "'); else return false;";
}
}
