Namespace: DevExpress.Utils

Assembly: DevExpress.Data.v23.2.dll

NuGet Package: DevExpress.Data

public static void InvokeTrusted(
    Action trustedAction
)

Public Shared Sub InvokeTrusted(
    trustedAction As Action
)

Remarks

DevExpress UI controls automatically detect potentially dangerous data types, block their deserialization, and throw a security-related exception.

If you trust a data source, call the InvokeTrusted method to turn off safe deserialization for certain sections of code:

C#

DevExpress.Utils.DeserializationSettings.InvokeTrusted(()=>{  
    using(var ms = new MemoryStream()){
        gridView1.SaveLayoutToStream(ms);  
        // Trusted source  
        ms.Position = 0;
        gridView2.RestoreLayoutFromStream(ms);  
    }  
});

VB.NET

DevExpress.Utils.DeserializationSettings.InvokeTrusted(Sub()
        ' Trusted source
    Using ms = New MemoryStream()
        gridView1.SaveLayoutToStream(ms)
        ms.Position = 0
        gridView2.RestoreLayoutFromStream(ms)
    End Using
End Sub)
