Dynamically show/hide custom summary rows at runtime

[James Blibo]

I have created a couple of custom summary rows and empty rows above the ggc header. Can I dymanically show or hide these rows at runtime based on a user preference?

Hi James,

Use ShowSummaries property to hide/show the summary row in a grid. Here is a code snippet

//To hide the main table summary row.
this.gridGroupingControl1.TopLevelGroupOptions.ShowSummaries = false;

//To hide the nested table summary row.
this.gridGroupingControl1.NestedTableGroupOptions.ShowSummaries = false;

//To hide a particular grouped column summary row.
this.gridGroupingControl1.TableDescriptor.Columns["Col2"].GroupByOptions.ShowSummaries = false;

None and all of these settings do not work for me. I have a custom grouping engine in my project! Could this be responsible?

Hi James,

You need to check the ShowSummaries property in IsChildVisible override method [ChildTable derived class] . Below is a code snippet.

public class GroupingChildTable : ChildTable, IGridGroupOptionsSource
{
public override bool IsChildVisible(Element el)
{
if (this.IsTopLevelGroup)
{
if( el.Kind == DisplayElementKind.Summary )
{
return this.Engine.TopLevelGroupOptions.ShowSummaries;
}
//Your code heree....
}
}
}

Here is a sample.
