Currently I am trying to get the state of a checkbox that is set to indeterminate. I have a list of TreeNodes and am iterating through each node and adding information from each node to a list. Currently it is adding information based off of if the node is checked.
We have found we need to also include if the node's checkbox is set to indeterminate as well.
I know I can get this value in a roundabout way using JQuery but am interested in seeing if you have any built in functionality or other ways to get if the checkbox is set to indeterminate.
