引起系统的按钮OnClick事件的重复器.无效的回发或回调参数

本文关键字:无效 回调 参数 系统 按钮 OnClick 事件 | 更新日期: 2023-09-27 18:18:04

我目前正在使用一个中继器来制作按钮列表。每个按钮都有一个on click事件,该事件将从列表中的重复器中删除该项目。然而,当我点击任何按钮时,我得到一个错误System.ArgumentException: Invalid postback or callback argument。我在看这个答案。我不想禁用EnableEventValidation(这样做有安全风险)。有没有更好的解决办法?

错误:

    <ContentTemplate>
        <div id="divMainContent" runat="server">
            <asp:Repeater ID="repeaterCameras" runat="server">
                <ItemTemplate>
                        <div>
                            <asp:Button ID="locRemoveCameraButton" runat="server"
                                OnClientClick="return clickRemoveCamera(this)" OnClick="RemoveCamera"
                                Text="Remove" meta:resourcekey="btnRemoveCamera"
                                data-camera-position='<%# Eval("Position") %>'></asp:Button>
                        </div>
                </ItemTemplate>
            </asp:Repeater>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

clickRemoveCamera只是一个空的JavaScript方法。locAddCameraButton是一个按钮,用于添加到中继器列表中。我试过删除AsyncPostBackTrigger和删除UpdateMode="Conditional"。还是不行

c#

:

protected void RemoveCamera(object sender, EventArgs e)
{
    if (sender == null)
        return;
    Button removeCameraButton = (Button)sender;
    string buttonClickPos = removeCameraButton.Attributes["data-camera-position"];
    System.Diagnostics.Debug.WriteLine("buttonClickPos = " + buttonClickPos);
    foreach (RepeaterCamera rc in repeaterCamerasList)
    {
        if(string.Equals(rc.Position.ToString(), buttonClickPos)){
            System.Diagnostics.Debug.WriteLine("Found camera in repeater");
        }
    }
}

我明白了。在我的Page_Load我改变了中继器。我应该只在!IsPostBack期间这样做(我没有)。所以我添加了这个,它起作用了
