TreeView inside a ListView

[mylixes]

How could I include a treeView inside a ListView?

I'm not sure if you can do that with any built in .NET controls. You might want to look at using a custom control. I'm not entirely sure of what functionality you're looking for, but if it's the grid presentation with treeview functionality, the following article may be of use to you.

I used this on a project in the past and with fairly minimal enhancement it worked quite well for me :)

Thanks Gary for the reply. the link you shared helps me a lot. but I had encountered another problem using the expandable datagridView.

My datagrid consists of 4 columns, string column (treeView), combobox, linklabel and string column. Below is my code.

foreach (KeyValuePair<int, string[]> name in nameDictionary)
            {
                parentNameNode = helper.getName(name.Value[i]);
 
                //treeView1.Font = new Font(null, FontStyle.Bold);
                parentNode = rootNode.Nodes.Add(parentNameNode);
                parentNode.DefaultCellStyle.Font = new Font("Verdana", 7, FontStyle.Bold);
 
                if (name.Value.Length > 1)
                {
 
                    for (int a = 0; a < name.Value.Length; a++)
                    {
 
                        childNode = parentNode.Nodes.Add(readerName.Value[a], "aaaa", "Start");
                        childNode.DefaultCellStyle.Font = new Font("Verdana", 7, FontStyle.Regular);
 
 
                    }
                }
