Passing additional parameters to custom data binding (DataAdapter)

Admir Hodžic

Asked On January 10, 2020 07:06 PM UTC

I am trying to implement Custom data adapter as service.

Is there a way to pass additional parameters custom methods eg

`public override object Read(DataManagerRequest dm, string key = null)`

Something like was shown in this post how-to-pass-additional-parameter-when-using-datamanager-in-grid

Use case for passing parameters from razor page / component to custom DataAdatper service is passing userId to service so we can filter records according to user requesting data for grid, also sometimes my forms has additional filters set beyond scopes of grid columns.

Hi Admir,

Greetings from Syncfusion support.

Query: “Is there a way to pass additional parameters custom methods eg ”

We have already documented your requirement in our UG documentation section. Kindly refer the below documentation for your reference.

https://ej2.syncfusion.com/blazor/documentation/grid/custom-binding/?no-cache=1#custom-adaptor-as-component

if you want to send additional parameters, kindly use Query property of EjsGrid to achieve your requirement.

@using Syncfusion.EJ2.Blazor.Data

@using Syncfusion.EJ2.Blazor.Grids

<EjsGrid TValue="Order" ID="Grid" AllowSorting="true" Query="@Query" AllowFiltering="true" AllowPaging="true">

. . . . . . .. . . . . .

</EjsGrid>

@code{

public static List<Order> Orders { get; set; }

public Query Query = new Query().AddParams("Code", 10);

You can get the values in Params property of DataManagerRequest class (Refer above screenshot). Kindly refer the below documentation for your reference

https://ej2.syncfusion.com/blazor/documentation/grid/data-binding/#sending-additional-parameters-to-the-server

Please get back to us if you have further queries.

Regards,

Vignesh Natarajan.

Thank you, a lot.

Apologies for opening ticket, I did know that I thought that adding query only works with DataManager attached to url (remote data).

Hi Admir,

Thanks for the update.

Query property can be used without the EjsDataManager. Using Query property we can filter, sort, send additional parameters to modify the Grid datasource with or without DataManager. We are glad to hear that you are able to achieve your requirement.

Kindly get back to us if you have further queries.

Regards,

Vignesh Natarajan.
