Getting Item Type from GridView

[David]

Hi

Is there a simple way to obtain the Item Type of the  items in the source collection of RadGridView?

I see that there is an Items.ItemType property, but this always seems to be null.

 

Thanks for any help.

 

Kind regards

Dave

Hi Dave,

Indeed, the ItemType property is not actually set by the RadGridView control but is instead there to be defined by the developer if the type cannot be automatically inferred by its data engine and leads to issues with the data operations (such as sorting, filtering, and grouping) of the control.

What I can suggest is to use a QueryableCollectionView as the ItemsSource for the RadGridView control which also exposes a constructor to set the ItemType. For example:

        private QueryableCollectionView data;

        public QueryableCollectionView Data
        {
            get
            {
                if (this.data == null)
                {
                    this.data = new QueryableCollectionView(new List<string>() { "one", "two" }, typeof(string));

                }

                return this.data;
            }
        }

You can then use the ItemType of this view to handle your custom logic:

            var qcv = this.GridView.Items.SourceCollection as QueryableCollectionView;
            var itemType = qcv.ItemType;

Please let me know whether such an approach would work for you.
