GGC Filter Nested Tables

[Administrator]

Probably this has been asked before, but I can not find the answer.

Is there an example that shows how to enable the filterbar for child (nested groups) in GGC where DataSource is set to a DataSet with defined relations.

Thank you

Hi Ivan,
Please, refer to the Broswer sample ( \\windows\Grid.Grouping.Windows\Samples\FilterBar ) and the set following property to enable the filterbar for child (nested groups)

this.groupingGrid1.TableDescriptor.ChildGroupOptions.ShowFilterBar = true;

// or using designer mode ( In Properties Window )
TableDescriptor - > ChildGroupOptions - > ShowFilterBar to true

Best Regards,
Madhan.

Madhan,
This example use a DataSet with a single table and no relations.

In my case there are no grouped columns created.
Is there a way to display/utilize filter bar in this case?

Thank you

I found that the correct propery path would be
NestedTableGroupOptions- > ShowFilterBar.

This works great, but is it possible to modify filtering logic in the way , that only parent records, which have child records are shown (filter by child)?

Thank you

Hi Ivan, If you meant, the filtering of parent table filterbar. Here is one way of implementing it, using currentcellshowingdropdown event. Here is a sample project. or if you meant some other logic, provide us more explanation. Best Regards, Madhan.
