    [CLOSED] [1.0] TreePanel Checked

    Hello,

    How can I make all nodes in a TreePanel checked without sending along the checked: true / false on the items bound to the TreePanel? Would be nice if we had a Checkable="true" on the TreePanel itself.

    Cheers,
    Timothy

    Hi,

    Agreed, it would be helpful feature.

    It can be implemented through custom TreeNodeUI class but it needs to set for each TreeNode also...

    I can suggest you the following thing, see BeforeRender listener of TreePanel.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.Net Example</title>
</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server">
        <Listeners>
            <DocumentReady Handler="onReady();" />
        </Listeners>
    </ext:ResourceManager>
    <ext:TreePanel ID="TreePanel1" runat="server" AutoHeight="true">
        <Listeners>
            <BeforeRender Handler="this.getRootNode().cascade(function(node) {
                node.attributes.checked = false;   
            });" />
        </Listeners>
        <Root>
            <ext:TreeNode Text="Root (level 0)" Expanded="true">
                <Nodes>
                    <ext:TreeNode Text="Node1 (level 1)" Expanded="true">
                        <Nodes>
                            <ext:TreeNode Text="Node1 (level 2)" Expanded="true">
                                <Nodes>
                                    <ext:TreeNode Text="Node1 (level 3)" />
                                    <ext:TreeNode Text="Node2 (level 3)" />
                                </Nodes>
                            </ext:TreeNode>
                        </Nodes>
                    </ext:TreeNode>
                    <ext:TreeNode Text="Node2 (level 1)" Expanded="true">
                        <Nodes>
                            <ext:TreeNode Text="Node1 (level 2)" Expanded="true">
                                <Nodes>
                                    <ext:TreeNode Text="Node1 (level 3)" />
                                    <ext:TreeNode Text="Node2 (level 3)" />
                                </Nodes>
                            </ext:TreeNode>
                        </Nodes>
                    </ext:TreeNode>
                </Nodes>
            </ext:TreeNode>
        </Root>
    </ext:TreePanel>
    </form>
</body>

    Hi,

    I suggest to use BeforeAppend event because it will work with loader also
    <BeforeAppend Handler="if(!Ext.isDefined(node.attributes.checked)){node.attributes.checked = false;}" />
