Available now in the DXperience v15.1 release, we've introduced a useful improvement for working with the DevExpress MVC Form Layout extension.
Now it's much easier to configure a nested extension.
Form Layout - MVC
The DevExpress MVC Form Layout extension is great because it helps you to create beautiful forms.
The Problem
The Form Layout extension is a container control where it embeds other controls within it.
The problem is when you want to access one of these nested/embedded controls. To do this, previously, you would have to write some code like this:
settings.Items.Add(i => {
i.NestedExtensionType = FormLayoutNestedExtensionItemType.ComboBox;
var cbSettings = (ComboBoxSettings)itemSettings.NestedExtensionSettings;
cbSettings.Properties.ValueType = typeof(int);
…
});
Solution - Lambda Expression
Now with v15.1, it is simple because you can configure it using a lambda expression:
settings.Items.Add(i => {
i.NestedExtension().ComboBox(s => {
s.Properties.ValueType = typeof(int);
…
});
});
The new approach benefits you because you do not need have reference type or a separate variable for settings and properties.
And there's less code to write which makes the code more readable!
