Composite Component in C# does not show all attributes

Question

I have a system where I use a dataGridView to list the fields of a table through the property dataSource, and a textBox so that the written text serves as a filter (when I type something in textBox, use typed text to filter my table and update on dataSource of dataGridView).

I am learning C# and saw that in Visual Studio, I can create a Composite Component and wanted to create a component textBox and the dataGridView.

I started the creation with a dataGridView and a textBox and managed the new component (textBoxGrid).

Includes the new component (textBoxGrid) in my form and when I went looking for the property dataSource in the new component, it is not shown.

How do I make her visible?

Answer 1

You must create a "link" between your property datagridview and its component.

Something like this:

In your component just create a property with get, and set pointing to the property of the datagridview:

If you need to set the DataSource in design mode, the attributes should be added to the property.

[AttributeProvider(typeof(IListSource)), DefaultValue(null), RefreshProperties(RefreshProperties.Repaint)]
public Object DataSource
{
    get { return datagridview1.DataSource; }
    set { datagridview1.DataSource = value; }
}

See with the attribute in the property, the datasource is "unlocked"

Remember that every time you change the component you must give build in the project again to update.
