The purpose of a tree view is to show the child nodes only when the user expands the parent node. In other words, you should simply load the immediate children when parent is expanded. Trying to load all tree at startup is a bad design idea. This table is small, so not a big problem here, but imagine it is huge.

Why would you force your users to wait for a full tree to load? Jose Rui Santos sir,i am a beginner in asp. Dhany; please change this line with this one ds. Add "Children", dtbl1.

Email Required, but never shown.This chapter describes the TreeTableView user interface component, which is a control designed to help you to visualize an unlimited hierarchy of data, presented in columns. The TreeTableView component has much in common with the TreeView and TableView controls: it combines and extends some aspects of their functionality. A basic implementation of a TreeTableView component in your application can be done by the following steps:.

In some cases, you can omit or hide the root element. Example implements these steps to create a simple tree table view control. The cell factory defined for the column specifies the content to be placed into this column for each tree item. When you compile and run Exampleit produces the output shown in Figure The next section shows you how to represent the personal data of the Sales Department employees from the Tree View use case.

Extend the use case described in the Tree View chapter and provide more information about each employee of the Sales Department. In Exampleyou modify the structure of data in the Employee class and define two properties corresponding to an employee's name and email address.

The TreeTableView component provides two columns to represent them, respectively. Inspect the code fragment shown in Example It creates cell factories for two columns. When you compile and run the application from Examplethe output shown in Figure appears. The default style of the tree table forces all tree elements to be expanded and all table columns to be shown. However, you can change these and other default settings by using the corresponding properties and methods of the TreeTableView and TreeTableColumn classes.

You can enable showing the table menu button, so that users of your application will be able to toggle the visibility of the table columns. Call the treeTableView. Figure captures the moment when a user hides the Employee column. The false value, passed to it, hides the root as shown in Figure You can sort data in columns by clicking the column headers and switching the sorting modes from ascending to descending and vice versa.

In addition to the built-in sorting support, data sorting is available through the TreeTableColumn and TreeTableView properties listed in Example The default selection model implemented for the TreeTableView class is defined in the MultipleSelectionModel abstract class that specifies the default value as SelectionMode. To enable multiple selection of the tree items and cells, use a combination of the setSelectionModel and setCellSelectionEnabled methods.

See Table for more information about available values and the resulting behavior.

For example, you can implement a selection of several cells in several rows for the TreeTableView component as shown in Example Figure shows the cells that you can select after the lines in are added to the code of the TreeTableViewSample application. Because the TreeTableView control encapsulates all features of table view and tree view, you might want to see the Table View and Tree View chapters for more information about additional capabilities.

Hi, Can any one of you can help me to create a tree structure.Download the latest release from the jQuery Plugin Registry or grab the source code from Github. Please report issues through Github issues. With this plugin you can display a tree in an HTML table, e. Why not use a list, you say? Because lists are great for displaying a tree, and tables are not.

Oh wait, but this plugin uses tables, doesn't it? Why do I use a table to display a list? Because I need multiple columns to display additional data besides the tree. One of the goals of jQuery treetable is to be as unobtrusive as possible. Being 'unobtrusive' is very cool nowadays, so that was an important requirement.

But it is cool for a reason: it keeps your HTML documents clean and it allows the code to degrade nicely when Javascript is not available. The treetable plugin only requires that you add specific data attributes to every row that is part of your tree. The plugin uses these attributes to determine what your tree looks like. Otherwise, it would have to guess the structure of the tree and it wouldn't be very successful in doing that. See the Usage chapter for more information on how to prepare your tree.

Note: This chapter assumes that you have already installed jQuery as described on their website. The plugin can either be installed manually or by using the Bower package manager. Note that the only listed dependency is jQuery. Copy the files jquery. Paste the following code right before the closing body tag in your HTML document.

Let's try to populate it. Add new Class Library Project. The solution is named Business Layer which contains an actual logic and an interaction with the database.

The class has a constructor to initialize SqlConnection and a method, which will take query in the string format and return rows in DataTable. This class contains a method that passes query to SqlAccess and returns the DataTable. So, give the referenc of BusinessLayer to PresentationLayer. Dharmraj Thakur Updated date, May 09 Step 1 Create a table and insert the records, as per your requirement.

The table structure is given below. Just run the query to make database and insert the records. You can insert records manually also. Create a new project and take Empty ASP. Here, I have used MVC 5 project. Step 4 Add new Class Library Project. Step 8 Add a new class named Category in PresentationLayer, which contains database structure properties.Who remembers Object Databases? At one time they were going to dominate the programming world.

Relational Databases remain king. Because Relational Databases are easy to understand and they work good… real good. Still, many times hierarchical data is stored in relational databases.

A common example is an organizational chart. This is usually stored in a single Employee table. This code shows how to go from a hierarchical table to a TreeView.

There is nothing sophisticated here, but a few tricks are needed to make it work. The first trick is to sort the records by the ParentID. We cannot insert a node into the tree until its parent node is in the tree. This implies a special case where the root node of the tree must be inserted first since it has no parent. The second trick is the use of XmlDocument.

Initially, I tried to go directly to a TreeView without the intermediate data object. But the TreeView control does not have functionality to find an arbitrary node given a node ID.

C# - Populate TreeView control with data from database

Writing a recursive find function seemed like a lot of work so we take advantage of the XPath search capabilities of XmlDocument to find an arbitrary Parent node. The third trick deals with an error in the documentation. Yes, until you run out of memory. There are many C to VB converters online. Thanks : It really helped me. I was going to write a recursive method and add the items one by one!

This seemed to work very well except if the parent id is not in order. Our table has an employee id and a supervisor id. Any ideas on how to make this same code work based on those two id's?

Re-read the paragraph that starts with: "The first trick is to sort the records by the ParentID.
