tabcontrol

问题 I'm using WebBrowser to write a program (let's call it < tinyWb >) to do some automatic web form filling jobs, etc., just for fun. < tinyWb > mainly does the following jobs: open a tabPage, navagate to a URL, do some business, and then close the tab. There are about 25 URLs total that need to be navigated to, but I found that the memory that the < tinyWb > program is occupying is growing continuously, and after about 10 hours it will require about 120m physical memory and about 240m virtual

问题 I am trying to make a basic window that uses a WPF TabControl to allow users to add new tabs. I want the end product to look somewhat like the way tabs work in a web browser where the last tab is just a "+" that when clicked it will add a new tab. I am trying to write the XAML code to set this up and I found that I can specify multiple DataTemplates within "TabControl.Resources" and based on the "DataType" the correct DataTemplate will be used to display the correct view for each tab... but

This behavior is unexpected as from what I understand, as the selected tab changes, the previously selected tabs content is unloaded first, so that you're only paying the price for one tabs content at a time. I've managed to simulate the behaviour with

问题 I am using a WPF tabcontrol to display items which are bound from a viewmodel. By default on start the first item of the list is selected but I want no item to be selected on start.

问题 My programs run like this: I have a form with an add button, save button, and tabcontrol. When the add button in the form is clicked, the tabcontrol will add more tabitem. And the tabitem is basically added from myframe which includes users key-in value in a TEdit.

My frame Image: My form Image: My

问题 I am having a strange problem with the .NET TabControl in C# (Visual Studio 2010). Start a Windows Forms Application. Add a tab control and a button. Add two different labels to the two tab pages so you can differentiate them. The purpose of the button is just to act as a next button; subscribe to the its Click event with the code: tabControl1.SelectTab(1); Let's assume the user entered something wrong on the first tab, so when they try to go to the second tab we want to send them back, so
