DxMemo.BindValueMode Property

Specifies when to update the Memo editor’s text.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
[DefaultValue(BindValueMode.OnLostFocus)]
[Parameter]
public BindValueMode BindValueMode { get; set; }

#Property Value

Type Default Description
BindValueMode OnLostFocus

A BindValueMode enumeration value.

Available values:

Name Description
OnLostFocus

The editor value is updated after the editor loses focus.

OnInput

The editor value is updated whenever a user types.

OnDelayedInput

The editor value is updated with a delay after a user makes changes.

#Remarks

The Memo editor updates its Text property after a user changes the input text. The BindValueMode property allows you to specify when the update happens.

#OnLostFocus Mode

The default mode is OnLostFocus. The actual editor text is updated after a user changes the input text and removes focus.

#OnInput Mode

Set the editor’s BindValueMode property to OnInput to update the actual editor text each time when the user changes the input text:

Razor
<DxMemo @bind-Text="Value"
        BindValueMode="BindValueMode.OnInput" />

@code {
    string Value { get; set; } = null;
}

#OnDelayedInput Mode

Set the editor’s BindValueMode property to OnDelayedInput to delay text updates. If a user changes the input text, the editor does not react immediately - it waits for the user to be idle for a certain time (InputDelay). Once the idle interval elapses, the editor applies all accumulated text changes at once.

Use this mode if you want fewer text updates (better client-side performance) and not rely on input focus changes.

The following code snippet shows the Memo editor that updates its value after a user is idle for 1 second (1,000ms):

Razor
<DxMemo @bind-Text="Value"
        BindValueMode="BindValueMode.OnDelayedInput"
        InputDelay="1000" />

@code {
    string Value { get; set; } = null;
}
