Need help with asp c# treeview mouseover get node value/text

Question

I want to use a mouseover event to get the current node value/text from the mouseover on a treeview. This is using ASP C# treeview. Can anyone help!? Have not seen online any clear examples of this.

Hi @LeClair, Michael L. (Rumford) ,

Accroding to your description,as far as I think,you need to get and split the node's path to find the node's value.Just like this:

TreeView1.Attributes.Add("onmouseover", "return OnTreeMmouseover(event)");  
 
function OnTreeMmouseover(evt) {  
    var src = window.event != window.undefined ? window.event.srcElement : evt.target;  
    var nodeClick = src.tagName.toLowerCase() == "a";  
    if (nodeClick) {  
        var nodeText = src.innerText || src.innerHTML;  
        var nodeValue = GetNodeValue(src);   
        a lert("Text: " + nodeText + "," + "Value: " + nodeValue);  
    }  
    return false;  
}  
function GetNodeValue(node) {  
    var nodeValue = "";  
    var nodePath = node.href.substring(node.href.indexOf(",") + 2, node.href.length - 2);  
    var nodeValues = nodePath.split("\\");  
    if (nodeValues.length > 1)  
        nodeValue = nodeValues[nodeValues.length - 1];  
    else  
        nodeValue = nodeValues[0].substr(1);  
    return nodeValue;  
}
