Editable GridViewSummaryItem

[Emmanuel Dugas-Gallant]

Is there a way to create an override of the GridViewSummaryItem to get an editable summary item with an OnPropertyChanged event?

Hello Emmanuel,

Thank you for your question.

You can inherit GridViewSummaryItem and override its OnPropertyChanged method, Evaluate method and its virtual properties. The following code snippet demonstrates how to create and use a custom summary item:

public class CustomSummaryItem : GridViewSummaryItem
{
    public CustomSummaryItem(string name, string formatString, GridAggregateFunction aggregate)
        : base(name, formatString, aggregate)
    {
    }

    protected override void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        base.OnPropertyChanged(e);
    }

    public override object Evaluate(IHierarchicalRow row)
    {
        return base.Evaluate(row);
    }
}

CustomSummaryItem summaryItem = new CustomSummaryItem("ID", "{0}", GridAggregateFunction.Count);
GridViewSummaryRowItem summaryRowItem = new GridViewSummaryRowItem();
summaryRowItem.Add(summaryItem);
this.radGridView1.SummaryRowsTop.Add(summaryRowItem);

I hope it helps.

Actually, this code does not allow me to edit the cell in the SummaryRow.

Hi here is a screenshot of what I'm trying to do. In the summary rows, I would like to be able to have an editable cell (check the orange rectangle below the Final Gross Margin). Is this possible?

Thanks,

[Alexander]

Hello Emmanuel,

The current architecture of RadGridView does not allow adding editable cells in a summary row. We will consider adding this feature if more clients request it.
