中继器的ItemCommand不能与LinkButton一起触发
[英]ItemCommand of Repeater is not fire with LinkButton
问题描述
I have a Linkbutton inside a repeater and I want to delete the Item when the user clicks on the Linkbutton; 
我在中继器中有一个Linkbutton，当用户单击Linkbutton时，我想删除该项目。 in this case the LinkButton's ItemCommand event is not fired, my code is below: 在这种情况下，不会触发LinkButton的ItemCommand事件，我的代码如下：
<asp:Repeater ID="rptSubject" runat="server" OnItemCommand="rptSubject_OnItemCommand">
<ItemTemplate>
<tr>
<td><asp:CheckBox id="chkAll" runat="server"/></td>
<td><%#Eval("SubjectName") %></td>
<td>
<asp:ImageButton ID="imgbtnDelete" ImageUrl="~/assets/images/icons/delete.png" runat="server" CommandName="Delete" CommandArgument='<%#Eval("SubjectID") %>'/>
<asp:LinkButton ID="lnkEditCategory" runat="server" CommandName="EditCategory" CommandArgument='<%#Eval("SubjectID") %>' Text="Edit Category"></asp:LinkButton>
</td>
</tr>
</ItemTemplate>
my repeater's itemcommand event handler is: 我的中继器的itemcommand事件处理程序为：
protected void rptSubject_OnItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName.Equals("Delete"))
{
// some code
}
if (e.CommandName.Equals("EditCategory"))
{
// some code
}
}
when I click on the image button my item command event fires but when I click on the link button it doesn't. 当我单击图像按钮时，会触发我的项目命令事件，但是当我单击链接按钮时，它不会。

The following code works for me: 以下代码适用于我：
<%@ Page Language="C#" %>
<script type="text/c#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
var data = new[]
{
new
{
SubjectID = "1",
SubjectName = "subject name 1"
},
new
{
SubjectID = "2",
SubjectName = "subject name 2"
},
};
rptSubject.DataSource = data;
rptSubject.DataBind();
}
}
protected void RptSubject_OnItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName.Equals("Delete"))
{
// some code
}
if (e.CommandName.Equals("EditCategory"))
{
// some code
}
}
</script>

You also need to make sure you bind to the repeater explicitly 您还需要确保您明确绑定到转发器
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
AddHandler rptPages.ItemCommand, AddressOf rptPages_ItemCommand
End Sub
