我有三个 asp net 文本框，其中包含搜索表的搜索条件。我希望搜索像谷歌一样工作。当按下回车键以触发“回车”按钮上的单击事件时。click 事件永远不会触发。我该怎么做才能让它着火？

            </Columns>
        </asp:GridView>
    </div>
</asp:View>

</asp:MultiView>

这是后面的代码方法：

    protected void EnterKeyPressed_Click(object sender, EventArgs e)
    {
        ReloadData();
        this.Multiview1.ActiveViewIndex = 0;
    }

快速浏览一下，您是否尝试过在此处删除 return false ：

$("#<%=SVParentCategoryLinkTitle.ClientID %>").keydown(function (e) {
    if (e.which == 13) {
        __doPostBack("#<%=EnterKeyPressed.UniqueID %>", "");
        return false;
    }
})

如果有帮助，请查看此问题和答案：Default button not working in asp.net panel

如果焦点已经在面板内，DefaultButton则用于捕获Enter按键，例如，您必须将焦点移动到面板内的文本框等输入字段。如果焦点不在那里，它将无法工作。
