要求：我实现了一个功能，该功能通过根据值单击网格中的按钮来删除行。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，该方法也从数据库中删除记录。
问题：行已从网格中删除，但它们会在一/两秒后返回。真的很奇怪。我收到有关warningondirrty 的警告，但我已通过在商店中将其关闭来取消该消息（WarningOnDirty = false）。帮助 ：）

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);
}
}
}
后面的代码：
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
}
