Treeview control

Posted By:      Posted Date: October 20, 2010    Points: 0   Category :ASP.Net

I have a treeview control of 3 tiers. Can anyone tell me why some of my 3rd tier nodes are not getting added?



Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Public Sub BuildTree(ByVal id_ci_owner As String)
        Dim tier As Integer
        tier = 1


        Dim strSQL As String = "vc.dbo.BuildOwnerHierarchy"

        Dim oTable As New ISN.SqlHelper
        oTable.AddParameter("@id_ci_owner", id_ci_owner)
        oTable.AddParameter("@tier", 1)
        oTable.AddParameter("@id_parent", id_ci_owner)
        Dim dt As DataTable = oTable.ExecuteDataTable(CommandType.StoredProcedure, strSQL.ToString)

        Dim node As Integer = 0
        Dim row As DataRow

Having problems with the TreeView control.

I'm having problems with the TreeView Web Control.  What I am aiming to accomplish is to populate a TreeView control with my Active Directory information (similar to how it is structured in Active Directory Users and Computers) and when a node is selected, it's associated value is displayed in a text box.  I have the OnTreePopulate method and OnSelectedNodeChanged method implemented.  Each node has a name and value, which the value is the LDAP path I want displayed in the text box.  SelectAction = TreeNodeSelectAction and PopulateOnDemand =true.  Is there anything I'm missing? thanks, Pat

Problems with Treeview control and button


I have a page with an ExtJS window and a asp:TreeView control and a asp:button inside it. When I click in the button, it doesn't fire the onclick event. When I change the UseSubmitBehavior property to false, it does fire the event, but the treeview CheckedNodes.Count is equal zero. I don't use (intentionally) any AJAX component in this page, so, why the onclick button doesn't work without "UseSubmitBehavior=false"? And why my CheckedNodes.Count is always zero? I have another simple page (without any complex javascript library) with the same treeview and button objects, and all controls works fine.

Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.

Accessing the different controls inside a GridView control

how we can access a particular control which resides inside a GridView control. In this article I will show you how you can access different controls inside a GridView control. We will see how we can access a TextBox control, a DropDownList control and a ListBox control. If you are working with ASP.NET 1.X then you might want to check out my article Accessing Different Controls Inside a DataGrid.

In-Depth look at the GridView Control

In the last article we looked at few of the new controls available in Asp.net 2.0. We also talked about Grid View Control which has replaced the Asp.net 1.1 DataGrid control for good. In this article we will examine more features of the Grid View control. In this article we will see some of the common operations that can be performed using the GridView control. Apart from these operations there are many more functions that can be performed on the control and which we will see in the later articles

ASP.NET repeater control - databind with style

even used the inline editing features, which I at the time thought was the coolest way possible to write ASP.NET code ( I managed to write code to hide all other rows and only show the current one - the row being edited). With a nice looking EditTemplate it looked indeed very slick but it really turned into giant and hard to manage code behind files.

Creating Paging for a Repeater Control

A common question is "How do I implement paging within a Repeater?" Although the beauty of the Repeater control is its flexibility, you're on your own for building most functions. ASP.NET 2.0 has included some new controls that provide paging, as does the DataGrid in ASP.NET 1.1. However, this tip shows you how to roll your own paging for a simple data viewer.

Using TemplateFields in the GridView Control

The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.
