Repeated request with Custom DataManager

Good morning we are using the adaptation of the Data Manager Request through Js and I have observed that the request is made twice to the server and I do not see the error where it may be, I share my code.
  <ejs-grid id="Grid-Lineas"
                                          toolbarClick="toolbarClick"
                                          toolbar="@(new List<string>() { "Add", "Edit", "Delete"})"
                                          enableHover="true"
                                          created="created"
                                          actionFailure="actionFailure"
                                          actionBegin="actionBegin"
                                          actionComplete="actionComplete">
                                    <e-grid-editSettings allowAdding="true" allowDeleting="true" allowEditing="true"
                                                         mode="Dialog" template='#dialogtemplate' showDeleteConfirmDialog="true">
                                    </e-grid-editSettings>
My custom adapter :
 class CustomAdaptor extends ej.data.UrlAdaptor {
            processResponse(data, ds, query, xhr, request, changes) {
                if (!ej.base.isNullOrUndefined(data.message)) {
                    ej2Grid_showMessage(data.message);
                }
                if (!ej.base.isNullOrUndefined(data.data))
                    return data.data;
                else
                    return data;
            }
            beforeSend(args, xhr) {
                xhr.withCredentials = true;
                super.beforeSend(args, xhr);
            }
        }

Hi diego, 

Greetings from Syncfusion support. 

Before proceeding your query, could you please confirm that while request made twice while performing crud actions or grid actions. 

If you are getting repeated requests while Performing crud actions, that is the default behavior of the  Grid. 

  1. One request will be made for storing the data(Updating the data to server for Update or Delete or Insert)
  2. Another request is for getting the current view data according the page settings.

So to validate further could you please share the complete Grid code including code for Dialog template and network tab Screenshot which will be helpful for us to validate further about issue. 

Regards, 
Manivel

Hi diego, 

Thanks for your update. 

We have tried the same shared code example at our end. But it was working fine at our end. You can check the below screenshot, while the page is loading only one request is made to Server side to get the data for first page records. Please find the below tried example for your reference. 


Screenshot: 

 

Could you please share the below details, which will be helpful for us to validate further about issue. 

  1. Share the Syncfusion packages and Scripts version
  2. Share the video demonstration or Screenshot of the issue
  3. If possible try to replicate the issue in the given sample or share a simple issue replicated sample

Regards, 
Manivel
