In the following code snippet, the Grid is bound to a data collection available during synchronous component initialization.
Bind the Data
parameter to a C# field or property.
Populate this field or property with data in the OnInitialized lifecycle method.
@inject WeatherForecastService ForecastService

<Columns >
<DxGridDataColumn FieldName ="Date" DisplayFormat ="D" />
<DxGridDataColumn FieldName ="TemperatureC" Caption ="@( "Temp. (\x2103) " ) " Width ="120px" />

<DxGridDataColumn FieldName ="Forecast" />
<DxGridDataColumn FieldName ="CloudCover" />
</Columns >
