我想在gridview中点击删除后添加确认模式。 问题是，通过这个添加，即使我尝试删除另一行，也只对gridview的第一行进行删除。
我在gridview
中的itemtemplate中有以下代码
<asp:LinkButton ID="diagrafi" runat="server" type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#delete_Modal">
<asp:Image ID="Image1" Width="20px" runat="server" ImageUrl="images/del.png"/>
</asp:LinkButton>
<div class="modal fade" id="delete_Modal" tabindex="-2" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span></button>
<h4 class="modal-title">
delete command
</h4>
</div>
<div class="modal-body">
<p>
are you sure?…</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal" onclick="myFunction()"> cancel</button>
<asp:Button ID="epivevaiosi" CommandArgument='<%#Eval("kodikos")+"|"+Eval("tablename")%> '
CommandName="DeleteRow" runat="server" type="button" Text="Διαγραφή" class="btn btn-primary"/>
</div>
</div>
</div>
</div>
有没有办法将与被点击的行相关的正确参数传递给bootstrap模态？ 提前谢谢..
答案 0 :(得分：2)
是 - Bootstrap提供了一种将参数传递给模态的方法，但您需要重新编写gridview
开始之前 - 此处的示例代码生成gridview Delete命令，该命令将要求您在数据源中具有关联的删除查询。如果不这样做，可以将Delete $ N调用更改为MyConfirmedDelete，并在gridview RowCommand事件中处理删除
所以，开始......
您需要向gridview列添加一个包含简单按钮的基本模板字段，该字段不会导致回发并使用引导模式属性进行修改
<Columns>
<!--...other gridview fields... -->
<asp:TemplateField>
<ItemTemplate>
<button id="btnDeleteConfirm" runat="server" type="button"
class="btn btn-primary"
data-toggle="modal"
data-target="#deleteConfirmModal"
data-postcommand="">Delete</button>
</ItemTemplate>
</asp:TemplateField>
<!--...other gridview fields... -->
</Columns>
请注意属性data-postcommand=""。 postcommand是用户提供的数据属性，必须以data-为前缀才能使用模式。这将填入后面的代码中，并包含相应行的删除引用：
在VB背后的代码中：
Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
For Each gvr As GridViewRow In GridView1.Rows
Dim btn As HtmlButton = gvr.FindControl("btnDeleteConfirm")
Dim pbo As New PostBackOptions(GridView1,
String.Format("Delete${0}", gvr.RowIndex),
String.Empty, False, True, False, True, False, String.Empty)
If btn IsNot Nothing Then
btn.Attributes("data-postcommand") =
ClientScript.GetPostBackEventReference(pbo, True)
End If
Next
MyBase.Render(writer)
End Sub
在C＃背后的代码中：
using System.Web.UI.HtmlControls;//add this
protected override void Render(HtmlTextWriter writer){
foreach(GridViewRow gvr in Gridview1.Rows){
HtmlButton btn = gvr.FindControl("btnDeleteConfirm") as HtmlButton;
PostBackOptions pbo =new PostBackOptions(GridView1,
String.Format("Delete${0}", gvr.RowIndex),
String.Empty, false, true, false, true, false,
String.Empty);
if( btn != null){
btn.Attributes["data-postcommand"] =
ClientScript.GetPostBackEventReference(pbo, True);
}
}
base.Render(writer);
}
上面有几点需要注意：
PostBackOptions对象ClientScript.GetPostBackEventReference() 接下来，您必须将模态移出gridview，只需要一个模态。我把它放在了封闭</form>
这是Bootstrap website的修改示例
请注意<asp:LinkButton>替换
<!-- Modal -->
<div class="modal fade" id="deleteConfirmModal" tabindex="-1" role="dialog"
aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Delete</h4>
</div>
<div class="modal-body">
Delete...Really???
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<asp:LinkButton ID="LinkButton2" runat="server"
ClientIDMode="Static"
CssClass="btn btn-primary">LinkButton</asp:LinkButton>
</div>
</div>
</div>
</div>
根据Bootstrap文档，这里是执行参数替换的jquery：
<script type="text/javascript">
$('#deleteConfirmModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var pbcommand = button.data('postcommand') // Extract info from data-* attributes
var modal = $(this)
modal.find('#LinkButton2').attr('href', pbcommand);
});
</script>

由于modal的id属性，删除仅发生在第一行.Html不接受单个页面上具有相同名称的多个id属性。因此，当您单击删除时，会反复调用相同的模型。您需要为所有模态ID指定不同的名称。例如我遇到的类似问题我写了这段代码。
<asp:GridView ID="gvCustomerView"
CssClass="table table-striped table-bordered bootstrap-datatable datatable"
runat="server" AutoGenerateColumns="false"
EmptyDataText="No records found"
OnRowDeleting="gvCustomerView_RowDeleting"
DataKeyNames="Id"
ShowFooter="True"
AllowPaging="True"
PageSize="150"
OnRowCommand="gvCustomerView_RowCommand"
OnPageIndexChanging="gvCustomerView_PageIndexChanging">
<Columns>
<asp:BoundField HeaderText="Atoll" DataField="atoll_name"></asp:BoundField>
<asp:BoundField HeaderText="Island" DataField="iland_name"></asp:BoundField>
<asp:BoundField HeaderText="Area" DataField="area_name" />
<asp:BoundField HeaderText="Customer name" DataField="customer_name"></asp:BoundField>
<asp:BoundField HeaderText="Branch name" DataField="branch_name"></asp:BoundField>
<asp:BoundField HeaderText="Account Number" DataField="account_number"></asp:BoundField>
<asp:BoundField HeaderText="Password" DataField="password"></asp:BoundField>
<asp:TemplateField HeaderText="Blacklist">
<ItemTemplate>
<% if (Convert.ToBoolean(Session["edit"]))
{ %>
<a href="javascript:BlackEntry('<%#Eval("Id")%>')" class="btn btn-info btn-setting">Make Blacklist</a>
<% } %>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Settings">
<ItemTemplate>
<% if (Convert.ToBoolean(Session["edit"]))
{ %>
<a href="javascript:SettingsEntry('<%#Eval("Id")%>')"><i class="fa fa-cog"></i></a>
<% } %>
<%--settings dialog--%>
<div class="modal fade" id="<%#Eval("Id")%>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h3>Settings</h3>
</div>
<div class="modal-body">
<div class="control-group">
<div class="controls" style="margin: 10px">
<i class="fa fa-pencil-square-o" style="margin-top: 5px"></i>
<% if (Convert.ToBoolean(Session["edit"]))
{ %>
<asp:LinkButton ID="lnkEdit" CommandArgument='<%#Eval("Id")%>' CommandName="Action"
runat="server">Edit</asp:LinkButton>
<% } %>
</div>
<div class="controls" style="margin: 10px">
<i class="fa fa-eye" style="margin-top: 5px"></i>
<asp:LinkButton ID="lblView" runat="server" Text="View" CommandName="View"
CommandArgument='<%#Eval("Id")%>'></asp:LinkButton>
</div>
</div>
</div>
</div>
</div>
</div>
<%--End settings Dialogue--%>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<% if (Convert.ToBoolean(Session["delete"]))
{ %>
<asp:LinkButton OnClientClick="return window.confirm('Are you confirm to delete?')" CommandArgument='<%#Eval("Id")%>'
CommandName="Delete" runat="server"><i class="fa fa-close"></i></asp:LinkButton>
<% } %>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
在设置对话框注释上方查看我已将绑定数据的Id传递给SettingsEntry javascript函数，并且我还将设置模态的id属性设置为绑定数据的相应Id。 那么SettingsEntry javascript函数是这样的。
function SettingsEntry(id) {
$('#' + id).modal('show');
}
将它应用到你的盒子里，你很高兴。

这个javascript for tooltip消息为＆＃34; Shahid khan＆＃34;提到的
<script type="text/javascript">
$(document).ready(function () {
InitializeBootstrap();
});
// For Re-Binding Jquery after Partial Postback...
function InitializeBootstrap() {
$("[data-toggle=popover]").popover({ trigger: "hover" });
}
