Filter DataGridColumn with data from method

[svenbaus]

Hello together,

I would like to use a DataGrid which gets data from a database and where one column needs to be a calculated value. All columns should be filterable. That's why I started like this:

<DataGrid TItem="ProcessStepMessage" Data="processStep.ProcessStepMessages" Responsive Filterable Resizable>
	<DataGridColumn Field="@nameof(ProcessStepMessage.MessageInformationCategory)" Caption="@_processStepMessageLocalizer["MessageInformationCategory"]" CustomFilter="OnMessageCategoryCustomFilter">
		<FilterTemplate>
			@{
				var selectedMessageInformationCategoryFilter = @context.SearchValue?.ToString() ?? MessageInformationCategory.Information.ToString();
				<Select TValue="MessageInformationCategory" SelectedValue="Enum.Parse<MessageInformationCategory>(selectedMessageInformationCategoryFilter)" SelectedValueChanged="@(e => { selectedMessageInformationCategoryFilter = e.ToString(); context.TriggerFilterChange( selectedMessageInformationCategoryFilter ); })">
					@foreach (var messageInformationCategory in Enum.GetValues<MessageInformationCategory>())
					{
						<SelectItem Value="messageInformationCategory">@_messageInformationCategoryLocalizer[messageInformationCategory.ToString()]</SelectItem>
					}
				</Select>
			}
		</FilterTemplate>
	</DataGridColumn>
	<DataGridColumn Field="@nameof(ProcessStepMessage.Moment)" Caption="@_processStepMessageLocalizer["Moment"]" />
	<DataGridColumn Field="@nameof(ProcessStepMessage.Text)" Caption="@_processStepMessageLocalizer["Text"]" CustomFilter="OnTextCustomFilter">
		<DisplayTemplate>
			@(context?.GetMessageLocalized(_processStepMessageLocalizer))
		</DisplayTemplate>
	</DataGridColumn>
</DataGrid>

I'm facing the problem, that in delegate 'OnTextCustomFilter' I only get the clean data of 'ProcessStepMessage.Text', but I would need the translated data from '.GetMessageLocalized(_processStepMessageLocalizer)'. Is there a chance to get the ProcessStepMessage object or has anyone a better idea?

Thanks for your support :)

Hello @svenbaus you should have access to your TItem in CustomFilter, you will have to Localize the message again. Is this not feasible for you?
