How to get parent nodes selected base on childs selected nodes
posted

Hello!

I have two WebDataTrees in the same page, where I have to pass nodes from WebDataTree1(Select Data) to WebDataTree2(Selected Data). Then I have a button to save the the selected data in the database. It works fine, I'm using checkbox with TriState.

The problem is when I retrieve this data from the database, I have to repopulate the WebDataTree2 and check the nodes, so I make a "foreach" and check the nodes, but the parent nodes isn't getting checked.

I'd like to know how to select parent nodes as it happens when you click in a child checkbox and the parents get checked. Note that I have around 5 levels in the hierarchy of WebDataTree.

Thanks.

    Hello Jorge,

    Thank you for using our community.

    I have investigated your case and I would like to suggest you the following approach. You can set the Parent’s check state to Checked or Partial. If all of the children nodes are checked use

    node.ParentNode.CheckState = Infragistics.Web.UI.CheckBoxState.Checked;

    And when only few of the children nodes are checked use:

    node.ParentNode.CheckState = Infragistics.Web.UI.CheckBoxState.Partial;

    Please let me know how my suggestion work for you.
