C# get folderpath from TreeListNode in treeList devexpress-CodePudding

I use XtratreeList with fileExplorerAssistant. I have a problem when I want to get the path of the selected folder from treelist. Or I have a problem in getting the folder path from TreeListNode. Please help me.

My code is :

        private void frmMovieAddAuto_Load(object sender, EventArgs e)
    {
        // Scan for all partitions
        System.IO.DriveInfo[] driveList = System.IO.DriveInfo.GetDrives();
        foreach (var drive in driveList)
        {
            // Select only logical fixed partitions
            if (drive.DriveType == System.IO.DriveType.Fixed && drive.IsReady)
            {
                // Add each drive as a root node
                treeListExtension1.RootNodes.Add(new PathNode(drive.RootDirectory.ToString()));
            }
        }
    }

    private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        TreeListColumn columnname;
        columnname = treeList1.Columns[0];
        columnname.Caption = "Folder Name";

        List<TreeListNode> nodes = treeList1.GetNodeList();
        foreach (TreeListNode node in nodes)
        {
            if (node.Checked == true)
            {
                DirectoryInfo di = new DirectoryInfo(node.GetValue(columnname).ToString());

                foreach (FileInfo fi in di.GetFiles("*.avi;*.mpg;*.mpeg;*.mp4;*.mkv;*.divx;*.AVI;*.MPG;*.MPEG;*.MP4;*.MKV;*.DIVX", SearchOption.AllDirectories))
                {
                    //do something
                }
            }

        }
    }

CodePudding user response：

To get the path of the selected folder from the TreeList, you can use the FocusedNode property of the TreeList to access the currently selected node, and then use the GetValue() method to get the value of the column that contains the folder path.

Here's an example of how you could modify your code to get the folder path from the selected TreeListNode:

// Get the node that is currently focused (selected) in the TreeList
TreeListNode focusedNode = treeList1.FocusedNode;

// Get the column that contains the folder path
TreeListColumn folderPathColumn = treeList1.Columns[0];

// Get the value of the folder path column from the focused node
string folderPath = focusedNode.GetValue(folderPathColumn).ToString();

// Use the folder path to access the files in the selected folder
DirectoryInfo di = new DirectoryInfo(folderPath);
foreach (FileInfo fi in di.GetFiles("*.avi;*.mpg;*.mpeg;*.mp4;*.mkv;*.divx;*.AVI;*.MPG;*.MPEG;*.MP4;*.MKV;*.DIVX", SearchOption.AllDirectories))
{
    //do something
}
