You can specify the column’s Width property value in any absolute or relative units that your browser supports. The WidthChanged event fires when a column’s width changes.

In the following code snippet, the WidthChanged event fires after a user resizes the Date column:

@inject WeatherForecastService ForecastService

<DxGrid Data="@Data" ColumnResizeMode="GridColumnResizeMode.NextColumn">
    <Columns>
        <DxGridDataColumn FieldName="Date" DisplayFormat="D"
                          Width="150px" WidthChanged=@OnWidthChanged />
        <DxGridDataColumn FieldName="TemperatureC" />
        <DxGridDataColumn FieldName="TemperatureF" />
    </Columns>
</DxGrid>

The new width: @Message

@code {
    object Data { get; set; }
    string Message { get; set; }
    void OnWidthChanged(string NewValue) {
        Message = NewValue;
    }
    protected override void OnInitialized() {
        Data = ForecastService.GetForecast();
    }
}
