I am currently doing an evaluation of the tree grid to validate that it can satisfy our requirements and have a few questions around how to expose the grid data control functionality in the tree grid control.

This relates to data validation (from the error validation demo) and the column filtering (pasted similar question below):

http://www.syncfusion.com/support/forums/grid-aspnet/92141/GridTreeControl

I also have a question around the binding behaviour when there are different data objects. It looks like if the binding fails on an object of one type it will not attempt the binding again for objects of different types (probably for performance reasons), is there a way to change this so that the failed binding is read/only in the cell that failed but continues to attempt the binding for other objects other than creating an interim object that has an aggregate of all the properties?

Thanks

Hi Gregory,

Thanks for using Syncfusion products.

GridTreeControl uses GridControl for its internal operations like treeGrid.InternalGrid Currently, column filtering option is not available in GridTreeControl.
If you want column filtering, You can use our GridDataControl. We have simple and advanced filtering options in our GridDataControl.

Please find following sample in our Dashboard.

\WPF\Grid.WPF\Samples\3.5\WindowsSamples\Grid Data Control - Advanced\Advanced Filter Demo\

Binding the different data object for the data grid will not populate the source in the data grid. When a second object which has the different data type is bound to the data grid will not populate and fails in binding.

Please let us know if any queries.

Thanks
Kamal.

Are there plans to support filtering in the TreeGridControl in the future (within 2 years)?

I have noticed that the performance with large numbers of rows is very good when there is a hierarchy of items in the TreeGridControl but if there is a flat list with no hierarchy then the performance is not very good. Is there a setting that drives this or is the expectation to always have a hierarchy.

Thanks again,

Hi Gregory,

Thanks for your update.

We have made a feature request and currently we are investigating on the filter bar support in GridTreeControl. We will update you with the feature information with the timeline by 15th October 2010.

GridTreeControl does not provide any setting to populate the flat data grid without any hierarchy to get the performance. However we are investigating on this option and we will update your with the appropriate details on 15th October 2010.

Please let us know if any queries.

Thanks
Kamal.
