DxGrid.GetEditContext() Method

Returns the edit context.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public EditContext GetEditContext()

Returns

Type Description
EditContext

The edit context if the Grid is being edited; otherwise, null.

Remarks

Call this method to obtain the Grid’s edit context. This context allows you to check whether the data item was modified and its field values are valid. If the Grid is not in edit mode, the GetEditContext method returns null.

The following code snippet checks whether the edit row has unsaved changes:

@inject NwindDataService NwindDataService

<DxGrid @ref="Grid"
        Data="Data"
        KeyFieldName="EmployeeId"
        EditModelSaving="OnEditModelSaving"
        EditMode="GridEditMode.EditRow">
    <Columns>
        <DxGridCommandColumn />
        <DxGridDataColumn FieldName="FirstName" />
        <DxGridDataColumn FieldName="LastName" />
        <DxGridDataColumn FieldName="Title" />
        <DxGridDataColumn FieldName="HireDate" />
    </Columns>
</DxGrid>

@code {
    IGrid Grid { get; set; }
    IEnumerable<object> Data { get; set; }
    NorthwindContext Northwind { get; set; }

    async Task OnEditModelSaving(GridEditModelSavingEventArgs e) {
        if (Grid.GetEditContext().IsModified()) {
            // Save changes to the database
        }
    }
    // ...
}
