The application can be deployed to a web site, UNC folder, or CD/DVD. In launched mode, nothing is actually installed to the client computer. You can use ClickOnce in launched or installed mode.

#Msdn errorprovider update#

It relies on an application manifest, which describes the assemblies, dependencies, files, permissions, and update location, and the deployment manifest, which specifies the version number and location of the application manifest.

New (this.GoToSleep)) Īs covered in a previous article, ClickOnce is a mechanism for combining the reach of Web applications with the rich UI of a Windows Forms-based application through auto updateable Windows Forms.

The following sample code demonstrates the ability to call a method and have it process on a new thread, which would allow the UI to remain responsive: thread = new ( It is especially useful for long-running operations such as accessing resources across a network. You can use threads to perform processing in the background and increase the perceived responsiveness and performance of a WinForm app. OptionsPropertyGrid.SelectedObject = appset Ī prior set of articles ( Part 1, Part 2, and Part 3) contains much more detail about threading, but it is worth mentioning here. Create the class and display in PropertyGrid. OptionsPropertyGrid.Size = new Size(300, 250) PropertyGrid optionsPropertyGrid = new PropertyGrid() Below is sample code to create and display a simple property grid. It can use a serializable object with properties to display, save, and load state. It is a simple model for displaying property settings. The PropertyGrid control is a native control available within. This will avoid unnecessary painting and UI delay. Traverse the non-databound list and add, edit, or remove items. Rather, encapsulate a block of code with calls to BeginUpdate and EndUpdate. It will cause excessive screen painting if you use it. You also should avoid the use of Items.Clear() with non-databound lists. List = new ListViewItem('Item' + i.ToString()) Additionally, it performs other optimizations to the methods internally to ensure efficiency in the loading, as follows: ListViewItem list = new ListViewItem It automatically calls BeginUpdate and EndUpdate. You also can use the AddRange method to efficiently add an array of pre-created items. ListViewItem listItem = new ListViewItem('Item'+i.ToString() ) Here’s an example: listView1.BeginUpdate() The BeginUpdate and EndUpdate methods allow bulk operations to occur without causing excessive repainting. Loading items into controls such as ListView and TreeView causes a repainting after each change. To prevent your control from being populated multiple times, a good practice is to always set the DataSource property last on controls such as ComboBox and ListBox, as follows: comboBox1.ValueMember = 'Name'

This means your controls may inadvertently populate multiple times. When you change the ValueMember property on controls programmatically, it causes most controls to repopulate the data from the configured DataSource. Data Binding Optimizationĭata binding allows data to be processed automatically and displayed in controls such as ComboBox on the user interface (UI). You’ll need to have some level of familiarity with topics such as data binding and validation to follow along.

Rather than focusing on a specific feature, it covers a variety of topics that will assist you in building fully functional and well performing Windows Forms applications.
