Hide PropertyGridItem

[Pauli]

I view class instance in property grid and I want hide some of properties. How can I do it?

[Pauli]

Is it so that nobody does not know howto prevent property value to be shown in property grid. 

[Laksmono]

Use BrowsableAttribute and set to false to hide the property

public class A
{
          [Browsable(false)]
          public string HiddenProperty{ get; set; }
}

Hello Pauli and Laksmono,

Thank you both for writing.

The solution proposed by Laksmono is the right way to go in case you do not want the property to ever be added to the items collection of RadPropertyGrid. Another options is to set the Visible property of the particular item in the property grid Items collection:

this.radPropertyGrid1.Items["propertyName"].Visible = false;

I hope this is useful. Should you have further questions, I would be glad to help.

Thanks Ivan and Laksmono
I want to hide collections and Browsable is what I wanted but I can't use it because it prevents binding. Visible works well.

Hi,

I have to use this ".Visible" trick instead of using [Browsable(false)] attribute, because I have to use binding on these properties in another form.

It works fine, but unfortunaly the height of the RadPropertyGrid scrollbar don't ignore the hidden items (the scrollbar is the same if all items are shown or if i hide some of them. Please see attached image).

 Regards.

Hello Grégory,

Thank you for writing.

When you modify the item's visibility, it is necessary to wrap it in a BeginUpdate/EndUpdate block. Thus, the PropertyTableElement will be refreshed properly and the scroll-bar will recalculates its value:

public Form1()
{
    InitializeComponent();

    RadPropertyStore store = new RadPropertyStore();
    for (int i = 0; i < 8; i++)
    {
        PropertyStoreItem item = new PropertyStoreItem(typeof(string), "Prop" + i, "Value" + i);
        store.Add(item);
    }

    this.radPropertyGrid1.SelectedObject = store;
}

private void radButton1_Click(object sender, EventArgs e)
{
    this.radPropertyGrid1.PropertyGridElement.PropertyTableElement.BeginUpdate();
    this.radPropertyGrid1.Items["Prop5"].Visible = false;
    this.radPropertyGrid1.PropertyGridElement.PropertyTableElement.EndUpdate();
}

I hope this information helps. Should you have further questions, I would be glad to help.
