Properties
TabAlignment: Returns or sets the area of the control (for example, along the top) where the tabs are aligned.
Boolean: Returns or sets whether the user can change the position of a tab button by dragging it. (Default: False)
Boolean: Returns or sets the option to automatically activate the first focusable control of the TabPage when the SelectedTab is changed. Since 3.5.4 (Default: False)
BorderStyle: Indicates the border style for the control. (Default: Solid)
Display: Returns or sets the Display mode of the control to determine whether to display the icon, the text or both. (Default: Both)
Rectangle: Returns the display area of the control's tab pages.
ImageList: Returns or sets the images to display on the control's tabs. (Default: null)
Size: Returns or sets the fixed size of the tab buttons. The default value is Empty to use the itemSize set in the current theme or auto sizing.
When set to Empty (default) it uses the itemSize set in the theme. You can also set only the width or the height and leave the other value set to 0 to use the value in the current theme or auto sizing. The width (or height when Alignment is Left or Right) is applied when the value SizeMode is Fixed or Center. The height (or width when Alignment is Top or Bottom) is applied always.
Orientation: Returns or sets a value indicating the horizontal or vertical orientation of the TabControl tabs.
Int32: Returns the number of rows that are currently being displayed in the control's tab strip.
Int32: Returns or sets the number of pixels to scroll when the scroll buttons are pressed. (Default: 15)
Throws:
ArgumentOutOfRangeException The value is less than 1 or greater than 500.
Int32: Returns or sets the index of the currently selected tab page. (Default: -1)
Throws:
ArgumentOutOfRangeException The value is less than -1.
TabPage: Returns or sets the currently selected tab page.
Boolean: Returns or sets whether a tab's ToolTip is shown when the mouse passes over the tab. (Default: False)
Boolean: Returns or sets whether the tab visibility menu button is visible. (Default: False)
TabSizeMode: Returns or sets whether the tab buttons should fill the control's size, or placed in the center, or use the size set in ItemSize.
Int32: Gets the number of tabs in the tab strip.
TabPageCollection: Returns the collection of tab pages in this tab control.
Methods
Makes the tab following the tab with the specified index the current tab.
Throws:
ArgumentOutOfRangeException index is less than 0 or greater than the number of TabPage controls in the TabPages collection minus 1.
Makes the tab following the specified TabPage the current tab.
Throws:
ArgumentNullException tabPage is null.
Makes the tab following the tab with the specified name the current tab.
Throws:
ArgumentNullException tabPageName is null; or tabPageName does not match the Name property of any TabPage in the TabPages collection.
Returns the TabPage control at the specified location.
Returns: Control. The TabPage at the specified location.
Throws:
ArgumentOutOfRangeException index is less than 0 or greater than the number of TabPage controls in the TabPages collection minus 1.
Returns the bounding rectangle for the tab button of the TabPage at the specified index in this TabControl control.
| Parameter | Type | Description |
|---|---|---|
index | The zero-based index of the tab page for which to retrieve the bounding rectangle of the tab button. |
Returns: Rectangle. A Rectangle that represents the bounds of the specified tab.
Bounding rectangles for the tab buttons are received from the client and are updated asynchronously. If the application adds a tab page, or changes any property that causes the tab button to be resized (orientation, sizing, text, alignment, etc.) it cannot immediately after retrieve the new bounds. When the tab rectangles are updated, the TabControl will fire the StyleChanged event to inform the application that the bounding rectangles have been updated. In alternative, you can use the GetTabRect and GetTabRectAsync overloads to query the client and receive the new bounding rectangle for the request tab page. Bounding rectangles are always empty until the TabControl has been rendered on the client. Throws:
ArgumentOutOfRangeException The index is less than zero; or the index is greater than or equal to TabCount.
Retrieves the bounding rectangle for the tab button of the TabPage at the specified index in this TabControl control.
| Parameter | Type | Description |
|---|---|---|
index | The zero-based index of the tab page for which to retrieve the bounding rectangle of the tab button. | |
callback | Callback method that will receive the bounding rectangle for the request tab button. |
Bounding rectangles are always empty until the TabControl has been rendered on the client. Throws:
ArgumentOutOfRangeException The index is less than zero; or the index is greater than or equal to Count.
ArgumentNullException The callback method is null.
Retrieves the bounding rectangle for the tab button of the TabPage at the specified index in this TabControl control.
| Parameter | Type | Description |
|---|---|---|
index | The zero-based index of the tab page for which to retrieve the bounding rectangle of the tab button. |
Returns: Task<Rectangle>.
Bounding rectangles are always empty until the TabControl has been rendered on the client. Throws:
ArgumentOutOfRangeException The index is less than zero; or the index is greater than or equal to Count.
Makes the tab with the specified index the current tab.
Throws:
ArgumentOutOfRangeException index is less than 0 or greater than the number of TabPage controls in the TabPages collection minus 1.
Makes the specified TabPage the current tab.
Throws:
ArgumentNullException tabPage is null.
Makes the tab with the specified name the current tab.
Throws:
ArgumentNullException tabPageName is null; or tabPageName does not match the Name property of any TabPage in the TabPages collection.
