【问题描述】:
我有一个带有用于删除数据行的按钮的 Gridview。我正在尝试通过 jQueryUI 对话框实现模式弹出窗口,以便在单击“删除数据”后提示用户,如果他们单击是,则该行将被删除,如果否,则没有任何反应。似乎如果我不向 onClientClick 添加“return false”,则无论单击按钮,该行都会被删除。如果我包含 return false,我不确定如何让 gridviewrow 命令实际发生。以下是一些当前的 sn-ps:
在脚本标签中:
function ShowPopup() {
$(function () {
var message = "Are you sure you want to Remove Data?";
$("#dialog").html(message);
$("#dialog").dialog(
{
title: "Data Removal Confirmation",
buttons: {
Yes: function () {
return true;
},
No: function () {
$(this).dialog('close');
}
},
modal: true
});
});
}
对话区:
<div id="dialog" style="display: none">
Gridview 按钮:
<asp:TemplateField HeaderText="Reject">
<ItemTemplate>
<asp:Button
ID="btnRemove"
runat="server"
Text="Remove Data"
CssClass="inherited, RemoveData"
CommandName="RemoveData"
Style="white-space: normal;"
OnClientClick="javascript: ShowPopup();return false;"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
代码隐藏:
else if (e.CommandName == "RemoveData")
{
int affected = 0;
affected = DAL.RemoveFileUploadItem((Guid)Session["UserId"], UploadId.ToString());
BindAll();
gv_PostUpload.DataSource = null;
string FileName = UploadId.ToString() + "-" + gvDashboard.DataKeys[index]["FileName"].ToString();
string mypath = Path.Combine(Global.data_directory, @"Watch"); // Server.MapPath("~/Data/Watch/");
string totalfn = Path.Combine(mypath, FileName);
if (File.Exists(totalfn))
File.Delete(totalfn);
DAL.LogActivity("Attempt removing file " + gvDashboard.DataKeys[index]["FileName"].ToString(), Utilities.GetCurrentPageFromURL(), Session["UserId"].ToString());
int affected = 0;
affected = DAL.RemoveFileUploadItem((Guid)Session["UserId"], UploadId.ToString());
if (affected != 0)
{
DAL.LogActivity(gvDashboard.DataKeys[index]["FileName"].ToString() + " removed ", Utilities.GetCurrentPageFromURL(), Session["UserId"].ToString());
}
BindAll();
gv_PostUploadZ.DataSource = null;
plnView.Visible = false;
plnViewZ.Visible = false;
plnErrorView.Visible = false;
}
以下是根据@albert-d-kallal 的回答修改后的按钮:
<asp:TemplateField HeaderText="Reject">
<ItemTemplate>
<asp:Button
ID="btnRemove"
runat="server"
Text="Remove Data"
CssClass="inherited, RemoveData"
CommandName="RemoveData"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
</ItemTemplate>
<ItemTemplate>
<asp:Button
ID="btnRemove2" ClientIDMode="Predictable"
runat="server"
Text="Remove Data"
CssClass="inherited, RemoveData"
Style="white-space: normal;"
OnClientClick='<%# "ShowPopUp(" + ((GridViewRow) Container).RowIndex + ");return false;" %>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
经过上述修改,这是我现在在检查按钮时看到的 n 个浏览器工具:
<input type="submit" name="ctl00$mainContent$gvDashboard$ctl02$btnRemove2" value="Remove Data" onclick="ShowPopUp(0);return false;" id="ctl00_mainContent_gvDashboard_ctl02_btnRemove2" class="inherited, RemoveData" style="white-space: normal;">
