RadGridView when AutoGeneratingColumn Column.ItemType is null

[W]

RadGridView when AutoGeneratingColumn(Event or override OnAutoGeneratingColumn) Column.ItemType is null.

How can I get ItemType?

Hello,

You can use ItemPropertyInfo argument of AutoGeneratingColumn event - args.ItemPropertyInfo.PropertyType .

I hope this helps.

Not PropertyType.

GridViewColumn.ItemType's summary : Gets the type of the item that the field belongs to.

GridView's items or ItemsSource is IEnumerable<T> or DataItemCollection or some type else.

How to get the item type "T" in AutoGeneratingColumn?

Is there any way to get "T" direct, not judge by GridView's items or ItemsSource?

Hello,

I am afraid that you can not use the ItemType property of GridViewColumn in AutoGeneratingColumn. However, you can use the GridView's Items property. In fact, the GridViewColumn.ItemType property is using a similar approach:

/// <summary>
        /// Gets the type of the item that the field belongs to.
        /// </summary>
        /// <value>The type of the item.</value>
        public virtual Type ItemType
        {
            get
            {
                if (this.DataControl != null)
                {
                    return this.DataControl.Items.ElementType;
                }

However, ElementType is internal, so you can't use it directly.

Thank you for answer me!

But "ElementType" is not public.So that only judged indirectly.
