Question

要求：我实现了一个函数，它通过根据值从我的网格中删除一个按钮来删除行。我的要求是从网格中删除状态为“Verwerkt”，“Ter Fiattering”，“Al verwerkt”的行，并在代码隐藏中添加一个方法，该方法也会从数据库中删除记录。

问题：行将从网格中删除，但它们会在一秒/两秒后返回。真的很奇怪。我收到了关于warningondirrty的警告，但我已经通过在商店关闭它取消了该消息（WarningOnDirty = false）。帮助：）

的GridPanel：

<ext:Panel runat="server" ID="panel" Height="0">
    <TopBar>
        <ext:Toolbar runat="server">

    </SelectionModel>
</ext:GridPanel>

函数javascript客户端删除行：

function MutatieLegen(grid) {
        var i = 0;
        //var store = Ext.getCmp("grid").getStore();
        if (grid.store.getCount() > 0) {
            for (i = grid.store.getCount() - 1; i >= 0; i--) {
                var status = grid.store.getAt(i).data["omschrijving"];
                if (status == "Verwerkt" || status == "Ter Fiattering" || status == "Al verwerkt") {
                    grid.store.removeAt(i);
                }
            }
        }

代码背后：

protected void btnClearSelection_Clicked(Object sender, DirectEventArgs e)
    {

       // Code behind logic. call sql to delete rows where status == Verwerkt or Ter   Fiattering or Al verwerkt

    }

我猜你在每个请求中重新绑定数据，确保用'if（！X.IsAjaxRequest）'

包装数据绑定

Ext.NET更改为gridpanel不需要的回滚
