Loop through Column Mappings

[Jeff Waddell]

Can anyone tell me how to loop through the column mappings at runtime?  I want to compare the property / column values of two objects by looping through and comparing only the properties that are mapped.

Hello Jeff Waddell,

You may try this approach and inform us if it meets your requirements:

public bool CompareItems (object item1, object item2, int columnIndex)
{
    var value1 = (clubsGrid.ItemContainerGenerator.ContainerFromItem(item1) as GridViewRow).ChildrenOfType<GridViewCell>().Where(c => c.Column == clubsGrid.Columns[columnIndex]).First().Value;
    var value2 = (clubsGrid.ItemContainerGenerator.ContainerFromItem(item2) as GridViewRow).ChildrenOfType<GridViewCell>().Where(c => c.Column == clubsGrid.Columns[columnIndex]).First().Value;
    if (value1 == value2)
        return true;
    return false;
}
