DxTreeViewNode.CheckedChanged Event

Fires when the node changes its checked state.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public EventCallback<bool?> CheckedChanged { get; set; }

Parameters

Type	Description
Nullable<Boolean>	The new Checked property value.

Remarks

The CheckedChanged event allows you to handle changes to the node’s Checked property value. The following code snippet changes the node’s Text when a user checks or unchecks the node:

<DxTreeView CheckMode="TreeViewCheckMode.Recursive">
    <Nodes>
        <DxTreeViewNode Text="Overview" />
        <DxTreeViewNode Text=@NodeText CheckedChanged=@CheckedChanged>
            <Nodes>
                <DxTreeViewNode Text="Combobox" />
                <DxTreeViewNode Text="Spin Edit" />
            </Nodes>
        </DxTreeViewNode>
        <DxTreeViewNode Text="Form Layout" />
        <DxTreeViewNode Text="TreeView" />
    </Nodes>
</DxTreeView>

@code {
    string NodeText { get; set; } = "Data Editors";
    void CheckedChanged(bool? Checked) {
        if (Checked == true)
            NodeText = "Data Editors (Staged Changes)";
        else
            NodeText = "Data Editors";
    }
}

If you want to handle such changes for all nodes in the same way, handle the DxTreeView.CheckedChanged event.
