I have a TreeListView as a view on a DxGrid populated with items (parent and child nodes). The row filter is not properly doing a search on the child nodes. If that is true, I have a datatemplate search text box on the column header and want to do a seach from MVVM
I also dont see ItemContainerStyle to set the IsSelected and IsExpanded to expand and select the node similar to TreeView control
How do I do it on TreeListView ?
Thank you for your question.
Filtering in TreeListView shows nothing if your FilterCriteria allows you to show only child nodes, without parent nodes. We have a suggestion and a workaround, so that the TreeListView will be able to show only child nodes when filtering: Filtering - Provide the capability to use all DXGrid filtering features for hierarchical data.
About expanding and selecting nodes - you can refer to these help topics: Expanding and Collapsing Nodes and Multiple Row Selection
Feel free to contact us if you need additional information. I will be glad to help you.
P.S. In order not to mix several problems in one thread, I would like to ask you not to post several problems in the same ticket as it may cause misunderstanding when different support engineers process your inquiry. Please open a new issue for each question you wish to ask.
