Remarks

An editor updates its Value or Text property after a user changes the input value. The editor’s BindValueMode property specifies when the update happens.

OnLostFocus Mode

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

OnInput Mode

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

razor
<DxTextBox @bind-Text="@TextValue" 
           BindValueMode="BindValueMode.OnInput" />

@code {
    string TextValue { get; set; } = "Test";
}

OnDelayedInput Mode

Set the editor’s BindValueMode property to OnDelayedInput to delay value updates. If a user changes the input value, 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 value changes at once.

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

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

razor
<DxTextBox @bind-Text="@TextValue" 
           BindValueMode="BindValueMode.OnDelayedInput"
           InputDelay="1000" />

@code {
    string TextValue { get; set; } = "Test";
}
