Based on an input in a textbox, I want to programmatically remove number of tab pages, i.e. if textbox input is 3 then only first 3 tabpages should be visible and tabpages 4 to 10 must be removed or should not be visible. I tried following without any success, For i = 0 To 9 Form1.TabControl1.TabPages.Remove(Form4.TabControl1.TabPages((val(textbox1.text)) + i)) Next (No exceptions or errors are generated for above statements) What is wrong with these statements?

Remove TabPage: Dispose or Clear or both?

阅读更多关于 Remove TabPage: Dispose or Clear or both?

问题 I am working on a windows form that has a TabControl named tabDocuments. I came across this piece of code that removes all pages from the TabControl. for (int i = tabDocuments.TabPages.Count - 1; i > -1; i--) { tabDocuments.TabPages[i].Dispose(); } tabDocuments.TabPages.Clear(); The person who wrote this code has already left a while ago. I am trying to understand why the code is calling Clear() after disposing each of the tabPages (looks un-necessary to me). Can anyone please explain to me

I've got a rather strange behavior on a TabControl, whose TabItems are all collapsed: The content of the first TabItem is still visible (but the header is not). The TabControl and its TabItems are setup like this: <TabControl> <TabItem Header="Data 1" Visibility="{Binding Path=DataTable1.HasRows, Converter={StaticResource BoolToVisibility}}"> <UI:ShowData DataContext="{Binding Path=DataTable1}"/> </TabItem> <TabItem Header="Data 2" Visibility="{Binding Path=DataTable2.HasRows, Converter={StaticResource BoolToVisibility}}"> <UI:ShowData DataContext="{Binding Path=DataTable2}"/> </TabItem> <

How to change the color of the selected tab in the TabControl?

阅读更多关于 How to change the color of the selected tab in the TabControl?

I am implementing a TabControl for a dialog box in WPF. The color of the selected tab (mouse-down) is white by default. I want to change the color of that selected tab to the color of hover (when I hover over a tab, the color of the tab changes to an Office-blue-gradient, which is what I want the color of the selected tab to be on mouse-click). How can I do that?

Can I remove the dotted focus rectangle over tabs on a TabControl?

阅读更多关于 Can I remove the dotted focus rectangle over tabs on a TabControl?

I have a tab control and need to remove the dotted focus rectangle around the selected tab. I have set the TabStop property of the TabControl to false. However if I click on a tab and press the Tab key, the dotted rectangle appears around the tabname.

I also tried overriding the MyTabControl.OnPaint()

WinForms Tab Control question

阅读更多关于 WinForms Tab Control question

I have a form that displays in two modes. Switching modes completely changes the appearance of the form much like you would expect if you were using a tab control and had a different layout of controls on each tab. A tab control would be perfect if I could hide the tab itself. Of course, I could use two panels and pro grammatically show and hide the appropriate panels. I tried this, but my anchoring keeps on getting messed up (I think it is a Visual Studio designer bug.) Ideally, I'd like to use a "wizard" control, which is tab-less, and at designtime, draw the controls for the first page,
