![]() Multiple selections can be dragged and dropped and can also be iterated programmatically.Ĭheck boxes can have a third "indeterminate" state to provide feedback to the user. RadTreeView allows multiple items to be selected using the Shift and Ctrl keys. You have the capability to attach a different context menu to each tree node. Context menusĮxpand RadTreeView functionality by adding context menus either for the entire control or to each node. RadTreeView can also load and save XML directly to file or string. RadTreeView binds to any object that supports IList, IListSource or IBindingList. RadTreeView binds to hierarchical data for most popular databases, custom business objects and XML. Load on demandįor industrial strength applications with heavy data requirements, the Load On Demand feature reduces loading time and performance overhead. You can build your own themes interactively using the Visual Style Builder or select one of the predefined themes. RadTreeView uses the innovative theming mechanism that the Telerik Presentation Framework (TPF) provides. Drag and drop behavior is customizable at the TreeView and node levels, allowing you to restrict interactions between source and target nodes. When dragging to a hidden or collapsed node the control will scroll up/down and automatically open the collapsed node. The position indication cursor provides feedback to the user so that nodes can be dropped above, below or within a given node. If ($ supports drag and drop within the same tree and between RadTreeView controls. $childNode = Add-Node $parentNode $_.Name “Cmdlet” $parentNode = Add-Node $script:cmdletNodes $_ “Module” $script:cmdletNodes.Name = “PowerShell Help” $script:cmdletNodes.text = “PowerShell Help” The following section of code shows the function we created to build the Windows PowerShell help tree: To build the Windows PowerShell help tree, we create a function and add it to the Form Load event- $form1.Add_Load(). Now, we need to build the tree and show it as the form loads. ![]() After this instance is created, we assign values to properties such as size, name, and various other properties. We use the namespace to create an instance as $treeView1. $treeView1.Location = $System_Drawing_Point The following snippet shows the code generated by PrimalForms to add the TreeView control to the main form: We need to build the tree and define what should happen when someone clicks on the nodes of the tree.īefore we go further in to the details of this script, let us quickly look at how the TreeView control is created.We need a list of Windows PowerShell core modules to display.We need to perform the following script changes to make the Windows PowerShell help tree complete.Now, we need to edit this script to add the custom code we need to create our process manager: This generates the necessary code to create the GUI form in Windows PowerShell. The intention of this form is to load the Windows PowerShell help for all Windows PowerShell core modules in the form of a tree, and when you select a cmdlet within the tree, help text for that cmdlet will be shown in the text box along with a link to a TechNet article at the bottom of the form.Īfter the design is complete, we export the form to a Windows PowerShell script using Export PowerShell option. This is seen in the image following this paragraph. I placed the TreeView control, a rich text box, a link label, and a button. I will explain this by showing an example of a Windows PowerShell help tree.įirst, we design a simple GUI form using SAPIEN’s PrimalForms Community Edition. In today’s post, we will see an example of how to use Windows Forms TreeView control. He is also moderator on the Official Hey, Scripting Guy! Forum and a regular speaker at BangaloreITPro User Group meetings. He writes regularly on his blog about topics related to Windows PowerShell, SharePoint, and Microsoft server virtualization. He loves automation and is a Windows PowerShell fanatic. Today we have a guest article by Ravikanth who works at Dell, Inc., as a lead engineer in the SharePoint Solutions Team.
