如果我没有添加任何土地成分价格/航班价格,我希望系统处理未使用的控制并向上移动以填补空白区域,但不知何故,或者更确切地说,它变成了这样。< / p>

结果:

enter image description here

if (bf.landComponent != 0.00m)
{
    lblLandComponent.Text = "" + bf.landComponent;
    lblLandComponent.Visible = true;
    lblLandComponentL.Visible = true;
}
else
{
    lblLandComponent.Dispose();
    lblLandComponentL.Dispose();
}

if (bf.flightComponent != 0.00m)
{
    lblFlightComponent.Text = "" + bf.flightComponent;
    lblFlightComponent.Visible = true;
    lblFlightComponentL.Visible = true;
}

if (bf.unitSales != 0.00m)
{
    lblUnitSales.Text = "" + bf.unitSales;
    lblUnitSales.Visible = true;
    lblUnitSalesL.Visible = true;

}

if(bf.rentalCar!=0.00m)
{
    lblCT.Visible = true;
    lblRentalCar_L.Visible = true;
    lblRentalCar.Visible = true;
    lblRentalCar.Text = "" + bf.rentalCar;
}

if (bf.discount != 0.00m)
{
   lblDiscount.Text = "" + bf.discount;
   lblDiscountL.Visible = true;
   lblDiscount.Visible = true;
}

if(bf.packageInclusion!="")
{
   lblPackageInclusion.Text = bf.packageInclusion;
   lblPackageInclusion.Visible = true;
   lblPackageInclusionL.Visible = true;
}
//BF is a class object stored in a session that i put from the previous page.

有什么不对吗?

Dispose方法不适用于您想要的内容。检查文档,看看它到底发生了什么。

如果要隐藏控件,请尝试将其可见性设置为false,或尝试将其从父容器控件中删除。

有条件地将Visibility设置为true是不够的。在99%的情况下,无论如何它们都是可见的,因为它是可见性的默认值。您必须确保将其初始可见性设置为false,或者添加将执行此操作的else子句。
