public abstract class GridCustomizeCellDisplayTextEventArgs :
GridCustomizeCellDisplayTextEventArgsBaseRemarks
Use GridCustomizeCellDisplayTextEventArgs (Value, FieldName, and so on) to specify the display format and access other grid data.
The following code snippet displays the Company Name values in the “Customer”:
@using Microsoft.EntityFrameworkCore
@inject IDbContextFactory<NorthwindContext> NorthwindContextFactory
@implements IDisposable
<DxGrid Data="GridDataSource"
CustomizeCellDisplayText="Grid_CustomizeCellDisplayText">
<Columns>
<DxGridDataColumn FieldName="OrderDate" DisplayFormat="d" />
<DxGridDataColumn FieldName="Customer" />
<DxGridDataColumn FieldName="ShipViaNavigation.CompanyName" />
<DxGridDataColumn FieldName="Freight" DisplayFormat="n2" />
</Columns>
</DxGrid>
@code {
object GridDataSource { get; set; }
NorthwindContext Northwind { get; set; }
IEnumerable<Customer> CustomerList { get; set; }
