Hi support,

I am adding a AggregateFunction to a gridcolumn with the following code:

bool showFooter = false;
foreach (var col in radGridView.Columns)
{
    if (col.UniqueName == "dauer") // Column with double-values
    {
        col.AggregateFunctions.Add(new SumFunction() { ResultFormatString = strFormat, SourceField = col.UniqueName });
        showFooter = true;
    }
}
radGridView.ShowColumnFooters = showFooter;

Adding a footer should only happens if my table has a column of data-type double named "dauer" otherwise columnfooters should not been shown. After doing this the footer has correctly been show but the first time the sum of the column is displayed when I sort a column of the grid via clicking on a column header.

You can reproduce this behavior in your sample-program "persistence framework / gridview serialization" when you put these lines of code in function "OnLoad" of Example.xaml.cs after calling this.EnsureLoadState() (of course you have to add a new column "dauer" to your dataset)

What do I have to do to show the results of the aggregate-function directly.

Thanks in advance
