RepositoryItemTrackBar.InplaceModeImmediatePostChanges Property

Gets or sets whether the in-place editor posts its value to the bound data source immediately after the value changes.

Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v25.1.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

[Browsable(true)]
public override DefaultBoolean InplaceModeImmediatePostChanges { get; set; }

VB.NET

<Browsable(True)>
Public Overrides Property InplaceModeImmediatePostChanges As DefaultBoolean

Property Value

Type	Description
DefaultBoolean	True to post the edit value to the bound data source immediately after the value changes; False to post the edit value after losing focus.

Available values:

Name	Description	Return Value
True	The value is true.	0
False	The value is false.	1
Default	The value is specified by a global option or a higher-level object.	2

Remarks

Enable the InplaceModeImmediatePostChanges option to ensure that dependent functionality reacts immediately to user input (for example, conditional formatting, data summaries, event handlers that rely on bound field values, etc.).

If the InplaceModeImmediatePostChanges property is set to DefaultBoolean.True, the editor posts its value to the data source as soon as its value changes (without waiting for the cell to lose focus). This behavior is supported by in-place editors where input does not rely on text editing:

• CheckEdit
• ToggleSwitch
• RadioGroup
• TrackBarControl
• RatingControl
• PopupBaseEdit descendants

If the InplaceModeImmediatePostChanges property is set to DefaultBoolean.False, the editor posts its value after losing focus (for example, when the user focuses another grid cell).

Tip

Set the InplaceModeImmediatePostChanges property to DefaultBoolean.Default and use the WindowsFormsSettings.InplaceEditorUpdateMode property to control update behavior globally:

• Immediate - Post the edit value immediately after the user modifies it.
• Postponed - Post the edit value when the cell loses focus.

Example

The following example:

• Binds the grid to a collection of Product objects.
• Creates a RepositoryItemCheckEdit that immediately posts changes to the grid’s data source.
• Creates an unbound column to display notes for out-of-stock products.
• Creates a conditional formatting rule to highlight out of stock products.

The following animation shows the result:
