[DefaultBindingPropertyEx("MarqueeAnimationSpeed")]

public class MarqueeProgressBarControl :
    ProgressBarBaseControl

<DefaultBindingPropertyEx("MarqueeAnimationSpeed")>
<DXLicenseWinFormsEditors>
Public Class MarqueeProgressBarControl
    Inherits ProgressBarBaseControl

Remarks

A marquee progress bar does not display progress. It is used to indicate that an operation is going on by continuously scrolling a block from left to right.

The time period, in milliseconds, that it takes the progress block to scroll across the progress bar is specified by the RepositoryItemMarqueeProgressBar.MarqueeAnimationSpeed property. Since the marquee animation speed is a time period, setting the value of this property to a higher number results in a slower speed and a lower number results in a faster speed.

The Text property specifies the text string that can be displayed within the progress bar. Its visibility is controlled by the RepositoryItemBaseProgressBar.ShowTitle property. In case the editor is embedded into a BarEditItem, you need to set up the BarEditItem.EditValue property to specify the progress bar text.

When the MarqueeProgressBarControl is embedded into the GridControl, the ColumnViewOptionsView.AnimationType property controls whether animation is enabled for all rows or only for the focused row.

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
