Getting value from SelectedItem RadGridView

Question

I'm using this List:

List<AssetListData> assetList = new List<AssetListData>();

Filled with data, and bind it to my RadGridView using this code:

AssetList_GridView.ItemsSource = assetList;

And now I have a GridView with two columns (Name and Type). I created a ContextMenu in AssetList_GridView consists of Edit and Delete. I need to get the value after I click the ContextMenu but it failed. I tried this code inside the click event in ContextMenu :

private void GridContextMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
        MenuItem item = (e.OriginalSource as RadMenuItem).DataContext as MenuItem;
        switch (item.Text)
        {
            case "Edit Asset":
                var typeValue = ((assetListData)AssetList_GridView.SelectedItem).assetType;
                this.AssetList_GridView.BeginEdit();
                break;
            case "Delete Asset":
                this.AssetList_GridView.Items.Remove(this.AssetList_GridView.SelectedItem);
                break;
        }
}

The error from var typeValue = ((assetListData)AssetList_GridView.SelectedItem).assetType; said that:

assetList could not be found.

Why can't I access assetList here, but I can access it for GridView ItemsSource? Is there any simple way to get value from the clicked row?

SelectedItem cant be retyped to LIST, if you want to retype it you should use

var typeValue = ((AssetListData)AssetList_GridView.SelectedItem).assetType;

Sir, what if i want to get both assetName and assetType? and what if i have more and want to get all the value in that Row? – Mirza Nov 19 '15 at 08:16

you can do var row = (AssetListData)AssetList_GridView.SelectedItem and you get whole ROW but not sure if that will work. Otherwise look http://stackoverflow.com/questions/5121186/datagrid-get-selected-rows-column-values – Slasko Nov 19 '15 at 08:24
