中继器 ItemCommand 不触发

Question

我已经尝试 post 同一主题，但没有成功。它实际上并没有触发事件

What I want

我要开火 ItemCommand 当有人点击转发器时的事件。

Issue

ItemCommand 未触发。

EnableViewState=true

代码如下：

Html:

<table>
              <asp:Repeater ID="outerRepeater" runat="server"
                    OnItemDataBound="outer_OnitemdataBound" 
                  onitemcommand="outerRepeater_ItemCommand">
                <ItemTemplate>
                <asp:Repeater ID="Rgallery" runat="server">
                    <ItemTemplate>
                      <%# (Container.ItemIndex + 4) % 4 == 0 ? "<tr>" : string.Empty %>  
                        <td>
                            <img src="<%# Eval("ImgPath") %>" style="height:300px; width:300px;" alt="" />
                                <div class="caption">
                         <h3><%# Eval("Type") %></h3>
                         <p><b><%# Eval("SubType") %></b></p>
                         <p{font-family: "Comic Sans MS", cursive, sans-serif; font-size: 25px}>Price:<i class="fa fa-inr fa-fw"><%# Eval("Price") %></i></p>
                         <p><asp:Button ID="btnBuy" CommandName="Buy" CommandArgument="Add to Cart" class="btn btn-primary" Text='<%# DataBinder.Eval(Container.DataItem, "Price") %>' runat="server" />
                         </p>
                        </div>
                        </td>
                        <%# (Container.ItemIndex + 4) % 4 == 3 ? "</tr>" : string.Empty%>
                    </ItemTemplate>
                </asp:Repeater>
                </ItemTemplate>
              </asp:Repeater>
              <asp:Label ID="lblStatus" runat="server" ></asp:Label>
    </table>

这是隐藏代码

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dummy = new DataTable();
        dummy.Columns.Add();
        dummy.Rows.Add();
        rptMain.DataSource = dummy;
        rptMain.DataBind();
        outerRepeater.DataSource = dummy;
        outerRepeater.DataBind();
    }
    if (Page.IsPostBack)
    { return; }

}

protected void outerRepeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    // Here is a code I want to fire
}
protected void outer_OnitemdataBound(object sender, RepeaterItemEventArgs e)
{
    Repeater repeater = e.Item.FindControl("RGallery") as Repeater;
    repeater.DataSource = db.GetTable("SELECT `Did`, `Type`, `SubType`, `Gender`, `Price`, `ImgPath` FROM `designs` ORDER BY `Did` DESC");
    repeater.DataBind();
}

What i have tried so far

方法一

我放了onItemCommand="rptthumbnail_ItemCommand"但是没成功

方法二我在 OnInit() 中添加了 handlar，但我也没有工作。

能否请一些人确定是什么问题请帮我解决这个问题......

因为您的按钮是内部中继器的子按钮，所以它会触发 ItemCommand 事件。将事件绑定向下移动到该转发器应该会为您修复它。

<asp:Repeater ID="outerRepeater" runat="server"
    OnItemDataBound="outer_OnitemdataBound">
    <ItemTemplate>
        <asp:Repeater ID="Rgallery" runat="server"
            OnItemCommand="Rgallery_ItemCommand">

protected void Rgallery_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    // Here is a code I want to fire
}

中继器 ItemCommand 不触发

Repeater ItemCommand Doesnt fire

asp.net

repeater

itemcommand
