我需要有关树视图控件的帮助。我在我的aspx页面中使用treeview控件，并使用存储过程从数据库绑定数据。我的输出很好，但我有一个问题，以显示树视图的员工详细信息。我的意思是如果用户单击树视图控件中的节点或值，我需要在树视图控件中显示所选值的详细信息。是否可以创建树视图的配置文件表..请帮我解决问题。
以下是我的代码
protected void Page_Load(object sender, EventArgs e)
{
if (Session["Username"] == null)
{
Session["Msg"] = "Your session has expired. please login again";
Response.Redirect("../Account/login.aspx");
//.........
return;
}
private void GetTreeViewItems()
{
try
{
string cs = ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString;
SqlConnection con = new SqlConnection(cs);
SqlDataAdapter da = new SqlDataAdapter("sp_GetEmployee", con);
DataSet ds = new DataSet();
da.Fill(ds);
ds.Relations.Add("ChildRows", ds.Tables[0].Columns["id"], ds.Tables[0].Columns["ManagerId"]);
foreach (DataRow level1DataRow in ds.Tables[0].Rows)
{
if (string.IsNullOrEmpty(level1DataRow["ManagerId"].ToString()))
{
TreeNode parentTreeNode = new TreeNode();
parentTreeNode.Text = level1DataRow["FirstName"].ToString();
// parentTreeNode.Text = level1DataRow["Designation"].ToString();
parentTreeNode.Value = level1DataRow["id"].ToString();
GetChildRows(level1DataRow, parentTreeNode);
TreeView1.Nodes.Add(parentTreeNode);
}
}
}
catch (Exception ex)
{
throw ex;
}
}
private void GetChildRows(DataRow dataRow, TreeNode treeNode)
{
DataRow[] childRows = dataRow.GetChildRows("ChildRows");
foreach (DataRow childRow in childRows)
{
TreeNode childTreeNode = new TreeNode();
childTreeNode.Text = childRow["FirstName"].ToString();
// childTreeNode.Text = childRow["Designation"].ToString();
childTreeNode.Value = childRow["id"].ToString();
treeNode.ChildNodes.Add(childTreeNode);
if (childRow.GetChildRows("ChildRows").Length > 0)
{
GetChildRows(childRow, childTreeNode);
}
}
}
protected void TreeView1_TreeNodeDataBound(object sender, TreeNodeEventArgs e)
{
}
protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
}
