c# - 从 TreeView 父节点中删除链接

Question

有没有一种方法可以保留父节点的文本但删除链接？ TreeView 父节点仅用作标题，没有导航。任何帮助都会很棒。谢谢。

private void BindNodes(string PtID)  
{  
    if (PtID != "")  
    {  
        int PatientID = Convert.ToInt32(PtID);  
        DBConnection dbObj = new DBConnection();  
        if (Session["Activepatient"] != null)  
        {  
            string[] SubChild = new string[4];  
            SubChild[0] = "Demographics";  
            SubChild[1] = "Medication Reviews";  
            SubChild[2] = "Drug Testing & Monitoring";  
            SubChild[3] = "Other Program";
            TreeNode oTrParent = new TreeNode();  
            //trv_patient.ParentNodeStyle = "None";
            //oTrParent.SelectAction.Style.Add("display", "none");
            TreeNode oTrSubChild1;
            TreeNode oTrSubChild;
            for (int i = 0; i < 4; i++)
            {
                oTrSubChild1 = new TreeNode();
                oTrSubChild1.Text = SubChild[i];
                if (i == 1)
                {
                    PatientInfoCollection patientCollection = new PatientInfoCollection();
                    patientCollection = dbObj.GetMedicationReviews(PatientID);
                    foreach (PatientInfo au in patientCollection)
                    {
                        oTrSubChild = new TreeNode();
                        PatientInfo Patient = new PatientInfo();
                        oTrSubChild.Text = au.DateRcvd.Value.ToString("MM-dd-yyyy")
                        oTrSubChild.Target = au.ReviewId.ToString();
                        oTrSubChild1.ChildNodes.Add(oTrSubChild);
                    }
                    oTrSubChild = new TreeNode();
                    oTrSubChild.Text = "Add Medication Review";
                    oTrSubChild.Target = "New";
                    oTrSubChild1.ChildNodes.Add(oTrSubChild);
                }
                trv_patient.Nodes.Add(oTrSubChild1);
            }
        }
    }
}

如果 temp 是这样的节点，您希望其文本是纯文本而不是链接，则使用下面的代码。

TreeNode temp = new TreeNode("text");
temp.SelectAction = TreeNodeSelectAction.None;
treeView1.Nodes.Add(temp);
