Is customizing the Grid edit dialog template supported? | Blazor Forums

VN Vignesh Natarajan Syncfusion Team July 8, 2019 01:43 AM

Hi Islam Yahia,

Thanks for contacting Syncfusion support.

Query: “I was looking for custom editor dialog template and I need to know if it's supported in the latest release or not yet”

In our 17.2.28 Nuget release we have provided the support for templates in Blazor components. Dialog Editing was also included in that release. You can achieve your requirement by defining the Template (as below) in the GridEditSettings. So kindly upgrade to our latest Nuget release (17.2.29) to achieve your requirement (Dialog Template)

Refer the below code example

<EjsGrid id="Grid" @ref="@grid" ModelType="@model" AllowPaging="true" DataSource="@data" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update" })">

<GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true" Mode="EditMode.Dialog">

@{

var employee = (context as Orders);

</colgroup>

<tbody>

<tr>

</td>

</div>

</td>

</tr>

</tbody>

</table>

}

</Template>

</GridEditSettings>

<GridColumns>

<GridColumn Field="OrderID" HeaderText="Order ID" IsPrimaryKey="true" TextAlign="@Syncfusion.EJ2.Blazor.Grids.TextAlign.Right" Width="90"></GridColumn>

<GridColumn Field="CustomerID" HeaderText="Customer ID" Width="90"></GridColumn>

<GridColumn Field="EmployeeID" HeaderText="Employee ID" Width="90"></GridColumn>

<GridColumn Field="Freight" HeaderText="Freight" Width="90"></GridColumn>

</GridColumns>

</EjsGrid>

………………………….

List<Orders> data;

private EjsGrid grid;

public List<Orders> order = new List<Orders>();

public Orders model = new Orders();

……………………………

Refer the below screenshot for the output

For your convenience we have prepared a sample using latest Nuget package (17.2.29).

Hi Vignesh Natarajan,

Thanks for your detailed answer. I have other three queries:

Query 1: The custom edit template throws .NET type conversion errors when the model properties are either of type byte[] or a nullable DateTimeOffset (nullable value types in general) and I think it\s a bug which needs to be addressed.

Query 2: When editing an existing record twice, the second time the dialog displays empty input elements, is this another bug or it's just in my code?

Query 3: How to distinguish whether the operation is an Add or Edit?

Hi Islam Yahia,

Thanks for the update.

Query1: “ The custom edit template throws .NET type conversion errors ”

From your query we suspect that you are facing issue while using cell edit template in Grid. If yes, currently we are implementing this feature at our end. This feature will be included in our subsequent NuGet release which is scheduled to be rolled out on or before 15^th July 2019.

You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.

https://www.syncfusion.com/feedback/7328/need-to-provide-cell-edit-template-support-for-blazor

Once the release is rolled out successfully, you will be able to achieve your requirement. If cell edit template is not the one you are using. Kindly share more detail about the issue you are facing.

Query2: “When editing an existing record twice, the second time the dialog displays empty input elements, is this another bug or it's just in my code?”

From your query we understand that you are facing issue while editing the same edited record for second time. We are able to reproduce the reported issue at our end while saving the records without any changes. We have considered the reported issue “Dialog template is not working properly during the second time editing” as a bug. Fix for the issue will be included in our subsequent NuGet release which is scheduled to be rolled out on or before 15^th July 2019.

You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.

Till then we appreciate your patience.

Query3: “ How to distinguish whether the operation is an Add or Edit?”

You can achieve your requirement using OnActionComplete and OnActionBegin events. OnActionComplete event will be triggered when certain action is completed. Similarly OnActionBegin event will be triggered when any Grid action begin.

So while editing, these events will be triggered and from its arguments we can get the requestType as Add or BeginEdit. Refer the below code example and screenshot for the output

<EjsGrid id="Grid" @ref="@grid" ModelType="@model" AllowPaging="true" DataSource="@data" OnActionBegin="onBegin" OnActionComplete="onComplete" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update" })">

………………………………………………………………..

</EjsGrid>

…………………………………………

public void onBegin(object args)

{

If(args.requestType == “Add”)

{

//perform your action here while adding a record

}

If(args.requestType == “BeginEdit”)

{

//perform your action here while editing a record

}

Note: We are facing some issue with strongly typed argument while using this (OnActionBegin and OnActionComplete) event in Blazor, and it will be resolved in our subsequest Nuget release which is expected to roll out on or before 15^th July.

You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.

Hi Vignesh Natarajan,

Thanks again for your detailed reply.

Is there a way to know if it\s an Add or an Edit method inside the template itself (e.g. by using a template directive).

Kind Regards,

Islam

Hi Islam,

Thanks for the update.

Query: “Is there a way to know if it\s an Add or an Edit method inside the template itself (e.g. by using a template directive). “

By default you cannot determine whether it is Add or Edit method inside the Dialog Template. But you can achieve your requirement using the value inside the template model. (i.e) There must be one column in dataSource which take boolean value (isAdd). In OnActionBegin event based on the RequestType argument value (Add or BeginEdit) we can change the value of Boolean property (isAdd) in the event arguments.

So that based on the isAdd property you can differentiate the Add or Edit inside the Dialog Template. But as mentioned in the previous update we have some issues with Strongly Typed arguments with OnActionBegin event. Once the Nuget release is successfully roll out you can achieve your requirement using below code example

<EjsGrid id="Grid" @ref="@grid" ModelType="@model" AllowPaging="true" DataSource="@data" OnActionBegin="onBegin" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update" })">

<GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true" Mode="EditMode.Dialog">

@{

var employee = (context as Orders);

@if (@employee.IsAdd.ToString() == "true") {

</colgroup>

<tbody>

<tr>

…………………………………………………

</tr>

</tbody>

</table>

}

else

{

</colgroup>

<tbody>

<tr>

…………………………………………………

</tr>

</tbody>

</table>

}

</Template>

</GridEditSettings>

<GridColumns>

………………………………………….

</GridColumns>

</EjsGrid>

………………………………………………………..

public void onBegin(ActionEventArgs args)

{

if(args.RequestType.ToString() == "Add")

{

var obj = JsonConvert.DeserializeObject<Orders>(JsonConvert.SerializeObject(args.RowData));

obj.IsAdd = true;

}

Till then we appreciate your patience.

Hello ;)

I downloaded the provided Sample: https://www.syncfusion.com/downloads/support/directtrac/145744/ze/DialogTemplate-1291209271

Updated Syncfusion.EJ2.Blazor to 17.2.0.40-beta with nuget,

private EjsGrid grid; -> private EjsGrid<Orders> grid;

Updated Scripts in _Host.cshtml

Everything ok.

Then I changed the Type of OrderID to Guid.

The Dialog does no longer work and "Newtonsoft.Json.JsonReaderException: Input string '0e7da30d-5726-4dfe-aa3e-a3c1d2ecc7a6' is not a valid number" error is in the console.

Is the "issue with strongly typed argument" already fixed in 17.2.0.40-beta?

I'm very new to syncfusion and blazor. Maybe I missed somthing, too ;)

Regards, Manuel
