tabcontrol

问题 I'm using a c# winform TabControl . I've created an ImageList , associated it with the TabControl and populated it with a few images. The problem is, when I set the ImageIndex or ImageKey for a particular tab the image shows up on the tab, but it covers the text that is on the tab. To add to my confusion, one TabPage in particular renders the image in the correct location (image followed by text). The page that has the image in the correct location is whatever TabPage I set the ImageIndex

问题 I am trying figure out how cancel this event in silverlight, sadly i didn't find any useful link with the solution :( (i saw some post for wpf wich i think are not longer available for silverlight) 回答1: Here is the bare bones of it:- bool cancellingTabSelectionChange = false; private void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (e.RemovedItems.Count > 0 && !cancellingTabSelectionChange) { cancellingTabSelectionChange = true; ((TabControl)sender)

问题 I have a WPF TabControl with a large number of tabs and they are presented in a sequential line all across the screen. Which means that a user needs to scroll sideways in order to view all the tabs. Is there a way to create two rows of tabs or make the long row of tabs "wrap" into two or more rows? 回答1: Wrapping is the default behavior for TabControl s. Any Style or ControlTemplate you're using that interferes with that? The following code: <Window x:Class="WpfApplication1.Window1" xmlns=

问题 i have a small program that takes a datatable (takes data from sql database) then splits it into datatable array by field and then should display it in a tabcontrol, each field in it's own tab the split, takes single datatable and splits into datatable array, works fine i think public DataTable[] splitTable(DataTable mainDT,string columnName) { int tmp=0; DataTable[] splitDT = new DataTable[11]; for (int i=0;i<11;i++) splitDT[i]=new DataTable(); foreach (DataRow row in mainDT.Rows) { tmp =

问题 I wish to have a Panel with the controls on it at design time but I want to add this panel to a desired tabPage of my TabControl at run time.

问题 I'm sure there is something simple that I am missing, but I must confess that at this point I am at a loss. I am programmatically adding TabItems to my main TabControl, one for each account that the user chooses to open. Before creating and adding a new TabItem I would like to check if the user already has the account open in another tab. I do not want to end up with two identical tabs open. Here is the code that I originally wrote. Hopefully it gives you an idea of what I am trying to

问题 I am creating a Text Editor Type app. I can have multiple editors open via tabs. In my first try, I used simple TextBox es to edit text. Everything worked ok. Then I created a UserControl encapsulating the text box + buttons to perform text manipulation eg. bold/italic etc. I found out that when I open different tabs, they all contain the same content. eg. In Tab1 i enter "hello world" that will appear in all tabs. There is "no separation" even though they are in different tabs <Window
