Question

我在主表单中设置了背景图片，然后在子表单中调用了它，它不起作用

我在主表单的属性中设置背景图像。如果我将其他任何工具（如按钮面板）放在子窗体上，就可以使用

主表格

if([Billing Doc. currency_WAERK] = 'USD',
sum({<[Billing Type_FKART] -={'ZG2','ZL2'}>}[Billing Sales Amount_NETWR])*139.2,
sum({<[Billing Type_FKART] -={'ZG2','ZL2'}>}[Billing Sales Amount_NETWR]))

子表格

在这里我这样称呼

Total Sales Variable = 
CALCULATE ( 
    SUMX ( 
        VALUES ( test_billing_doc_header[Billing Doc. currency_WAERK] ),
        IF ( 
            test_billing_doc_header[Billing Doc. currency_WAERK] = "USD",
            139.2,
            1
        ) * SUM ( test_biilingg_doc_item[Billing Sales Amount_NETWR] )
    ),
    test_billing_doc_header[Billing Type_FKART] <> "ZG2" && test_billing_doc_header[Billing Type_FKART] <> "ZL2"
)

Answer 1

首先创建BaseMasterForm.cs并继承Form。如果要在构造函数中添加一些内容，请编写代码。
第二个创建子Form.cs并继承BaseMasterForm。您可以覆盖显示背景。如果要显示背景，则需要设置为true。

BaseMasterForm .cs

public class BaseMasterForm : Form
{
    // You can override this Show Background. If you want or not to show background.
    public virtual bool ShowBackground { get { return true; } }

    public BaseMasterForm()
    {
        this.Load += (s, e) =>
        {
            // your image
            this.BackgroundImage = (ShowBackground) ? Properties.Resources.LeeQc : null;
            // you can custom
            this.BackgroundImageLayout = (ShowBackground) ? ImageLayout.Stretch : ImageLayout.None;
        };
    }
}

ChildForm.cs

public partial class ChildForm : BaseMasterForm
{
    // set true or false. to show MasterForm background.
    public override bool ShowBackground { get { return true; } }

    public ChildForm()
    {
        InitializeComponent();
    }
}

我认为它不起作用，因为每个页面都有它自己的属性。您必须在MasterForm中设置图片。

public partial class MasterForm: Form
{
    public MasterForm()
    {
        InitializeComponent();
        this.BackgroundImage = Properties.Resources.Image;
    }
}
