| Type | Default | Description |
|---|---|---|
| CheckState | Unchecked | A CheckState enumeration value that specifies the node’s check state. |
Remarks
If the TreeListOptionsBehavior.AllowIndeterminateCheckState option is disabled, a node can have two states: checked and unchecked. In this mode, to get/set check states, use the TreeListNode.Checked property.
If the TreeListOptionsBehavior.AllowIndeterminateCheckState option is enabled, three check states are supported: checked, unchecked and indeterminate. In this instance, use the CheckState property to get/set a node’s state.
See Node Checking - Checkboxes and Radio Buttons to learn more.
Example
The following code shows how to retrieve checked nodes using the TreeList.GetAllCheckedNodes method, and modify their values.
List<TreeListNode> list = treeList1.GetAllCheckedNodes();
foreach (TreeListNode node in list) {
decimal budget = Convert.ToDecimal(node["BUDGET"])*1.1m;
node["BUDGET"] = budget;
}
