UWP RadDataGrid: Disable a row

[Mohit Singh]

I am developing an UWP application where data is represented in tabular form using RadDataGrid. I want to disable a row depending on a property coming from ItemSource. User will not be able to select disable rows.

Is there any way to add this feature in RadDataGrid.

Any help would be highly appreciated.
Thanks in advance.

Hi, Mohit,

The control does not expose such mechanism out of the box, however, you can utilize the SelectionChanged event and check the items within the AddedItems property of the event args. Eventually, you can remove the items based on a property in your business model. For example:

private async void DataGrid_SelectionChanged(object sender, Telerik.UI.Xaml.Controls.Grid.DataGridSelectionChangedEventArgs e)
{
    await Task.Delay(10);
    if (e.AddedItems.Any())
    {
        foreach (Data item in e.AddedItems)
        {
            if (!item.CanBeSelected)
            {
                this.DataGrid.DeselectItem(item);
            }
        }
    }
}

As noticed, some delay is needed for the approach to work. I have attached a sample for your reference.

Adding to the previous post you can also use the columns CellContentTemplateSelector to change the visual appearance of each column depending on if they are disabled or not.

Hi, Cody,

Thanks for the follow-up. Indeed, it also seems a good idea to use such template selector and modify the appearance of the items that cannot be selected.
