treeview apartments

Recently, I started to seriously study the WPF/Silverlight technology at home. I saw the concept edition released by QQ in the previous section. It was amazing that Windows 7's Aero style was already very beautiful, however, the effects of the controls made by WPF are different from those made by the Windows 7 native. It is really good to have a project at hand. I want to write a few blog posts and hope some friends can discuss them and give me some advice. The

Treeview is a good control. Now we can see that many projects use it. It can implement the operation interface of MMC. Bytes Precautions during installation 1. Enter the.

This application is used in Treeview in winform. When the checkboxes mode is enabled for the Treeview, all its child nodes are selected when the parent node is selected. When the parent node is deselected, all its subnodes are also deselected. Implementation, very simple,CodeAs follows: /// Assume that the name of the Treeview is treeview1./// Private voidTr

I have seen many examples, all of which are bound to a class. No one said how to bind to an object. However, my absolute newbie is to bind to an object, and I can only find it myself: First, bind the data to the container, which has the following default conditions:① Metadata must be packaged in list or observablecollection, and the latter can be dynamically updated. That is, if the value of the observablecollection is changed in the program, the bound control is automatically updated.② The met

In the Treeview in win7, a problem may occur: when there are many nodes, the node in the last row may be ignored by the scroll bar. Unless the tree control is enlarged, it is difficult to operate on it. In fact, there is a very simple solution. Beginupdate and the corresponding endupdate are used when the node is loaded. As follows: Try { This. Treeview. beginupdate (); // Loadtreenodes... } Finally

Let's take a look at what aero-style tree looks like in windows. The above is a tree not implemented by WPF in the system. Most items have three additional States: Mouseover, selected, and selected and focused. Let's take a look at what the Treeview in WPF looks like by default. I believe you can see at a glance that this is clearly the XP style. The gap between tree and aero is too big. And the problem is serious. The following is an exa

Recently, a user asked me to write a demo program to demonstrate how to select a node in the Treeview so that all its child nodes are selected. The parent node changes the status based on the changes of the current node. During implementation, I did this in the aftercheck event of the Treeview. However, if the program has been run, the program overflows. Take a closer look, it turns out that when the checke
