BaseButton Class

Serves as a base for button controls.

Assembly : DevExpress.XtraEditors.v25.2.dll

NuGet Package : DevExpress.Win.Navigation

Declaration

C#
VB.NET

csharp

public class BaseButton :
    BaseStyleControl,
    IButtonControl,
    ISupportCommandBinding,
    ISupportToolTipsForm

Public Class BaseButton
    Inherits BaseStyleControl
    Implements IButtonControl,
               ISupportCommandBinding,
               ISupportToolTipsForm

Remarks

The BaseButton class implements the basic functionality of a regular button.

The BaseButton class implements an IButtonControl interface. Members of this interface allow you to use the button as a dialog button (BaseButton.DialogResult) or as the default button (BaseButton.NotifyDefault).

Do not create instances of the BaseButton class in applications. Instead, use the derived SimpleButton control. The descendant introduces additional functionality, allowing you to display images within buttons.

Tooltips

DevExpress controls support regular and super tooltips. Enable the ShowToolTips option to display tooltips when the mouse pointer hovers over the control.

Customize Regular Tooltip Text

Use the following properties of the target control to specify regular tooltip text and title:

API

Description

| | --- | --- | |

ToolTip

Specifies tooltip text. You can use line breaks in regular tooltips.

| |

AllowHtmlTextInToolTip

Specifies whether to parse HTML tags in text.

| |

ToolTipTitle

Specifies the tooltip title. If you do not specify tooltip text, the tooltip is not displayed even if you specify the title.

The following code snippet specifies tooltip text and title for a TextEdit editor:

C#
VB.NET

csharp

public Form1() {
  InitializeComponent();
  textEdit1.ShowToolTips = true;
  textEdit1.ToolTipTitle = "Name";
  textEdit1.ToolTip = "Please enter your name";
}

Public Sub New()
  InitializeComponent()
  textEdit1.ShowToolTips = True
  textEdit1.ToolTipTitle = "Name"
  textEdit1.ToolTip = "Please enter your name"
End Sub

Private Sub ToolTipController1_BeforeShow(ByVal sender As Object, ByVal e As ToolTipControllerShowEventArgs)
  Dim controller As ToolTipController = TryCast(sender, ToolTipController)
  If e.ToolTip = textEdit1.ToolTip Then
    e.ImageOptions.SvgImage = (TryCast(controller.ImageList, SvgImageCollection))("personalCard")
  End If
End Sub

Assign an Image to Regular Tooltips

Use the control’s ToolTipIconType property to assign a predefined icon. The ToolTipController.IconSize property specifies icon size.

Assign a custom image as follows:

Create a ToolTipController and assign it to the control’s ToolTipController property.
Create an image collection and assign it to the ToolTipController.ImageList property.
Handle the ToolTipController.BeforeShow event. Use the e.ImageOptions parameter to assign a raster or vector image to the tooltip.

Note

The ToolTipIconType property has priority over e.ImageOptions. If you assign a custom image, set ToolTipIconType to None.

The following code snippet assigns a custom image to the TextEdit tooltip:

Note

textEdit1, toolTipController1, and svgImageCollection1 were created at runtime.

C#
VB.NET

csharp

public Form1() {
  InitializeComponent();
  textEdit1.ShowToolTips = true;
  textEdit1.ToolTipTitle = "Name";
  textEdit1.ToolTip = "Please enter your name";
  textEdit1.ToolTipController = toolTipController1;
  toolTipController1.ImageList = svgImageCollection1;
  toolTipController1.BeforeShow += ToolTipController1_BeforeShow;
}

private void ToolTipController1_BeforeShow(object sender, ToolTipControllerShowEventArgs e) {
  ToolTipController controller = sender as ToolTipController;
  if (e.ToolTip == textEdit1.ToolTip)
    e.ImageOptions.SvgImage = (controller.ImageList as SvgImageCollection)["personalCard"];
}

Public Sub New()
  InitializeComponent()
  textEdit1.ShowToolTips = True
  textEdit1.ToolTipTitle = "Name"
  textEdit1.ToolTip = "Please enter your name"
  textEdit1.ToolTipController = toolTipController1
  toolTipController1.ImageList = svgImageCollection1
  AddHandler toolTipController1.BeforeShow, AddressOf ToolTipController1_BeforeShow
End Sub

Private Sub ToolTipController1_BeforeShow(ByVal sender As Object, ByVal e As ToolTipControllerShowEventArgs)
  Dim controller As ToolTipController = TryCast(sender, ToolTipController)
  If e.ToolTip = textEdit1.ToolTip Then
    e.ImageOptions.SvgImage = (TryCast(controller.ImageList, SvgImageCollection))("personalCard")
  End If
End Sub

Display a Super Tooltip

Use the control’s SuperTip property to assign a super tooltip. If you wish to use HTML tags in a super tooltip, enable the SuperToolTip.AllowHtmlText property.

Setting the ToolTipController.ToolTipType property to SuperTip converts existing regular tooltips to super tooltips.

Tip
