Remote loading with json

[Stefano Enrico]

Hi,

I update the version from 12.4.0.24 to 12.4.0.30, but the grid loading return this error message: "DataManager - executeLocal() : Json data is required to execute"

This is my json:

{"result":[
  {"IDCONT":"ID0","COG":"Cognome0","NOM":"Nome0","AZ":"Azienda0","TIT":0,"DES":"Stato0","RowNumberBc":0},
  {"IDCONT":"ID1","COG":"Cognome1","NOM":"Nome1","AZ":"Azienda1","TIT":1,"DES":"Stato1","RowNumberBc":1},
  {"IDCONT":"ID2","COG":"Cognome2","NOM":"Nome2","AZ":"Azienda2","TIT":2,"DES":"Stato2","RowNumberBc":2},
  {"IDCONT":"ID3","COG":"Cognome3","NOM":"Nome3","AZ":"Azienda3","TIT":3,"DES":"Stato3","RowNumberBc":3},

  {"IDCONT":"ID11","COG":"Cognome11","NOM":"Nome11","AZ":"Azienda11","TIT":11,"DES":"Stato11","RowNumberBc":11},
  {"IDCONT":"ID12","COG":"Cognome12","NOM":"Nome12","AZ":"Azienda12","TIT":12,"DES":"Stato12","RowNumberBc":12},
  {"IDCONT":"ID13","COG":"Cognome13","NOM":"Nome13","AZ":"Azienda13","TIT":13,"DES":"Stato13","RowNumberBc":13},
  {"IDCONT":"ID14","COG":"Cognome14","NOM":"Nome14","AZ":"Azienda14","TIT":14,"DES":"Stato14","RowNumberBc":14},
  {"IDCONT":"ID15","COG":"Cognome15","NOM":"Nome15","AZ":"Azienda15","TIT":15,"DES":"Stato15","RowNumberBc":15},
  {"IDCONT":"ID16","COG":"Cognome16","NOM":"Nome16","AZ":"Azienda16","TIT":16,"DES":"Stato16","RowNumberBc":16}
],
"count":100}

I use this datamanager

// DATA MANAGER

var dataManager = ej.DataManager({
    url: 'http://localhost:1128/_GRID',
    offline: false,
    adaptor: 'UrlAdaptor'
});

Thanks

Hi Stefano,

Thanks for using Syncfusion products.

Based on your provided code, we found that the error throws in selectRows event. Could you please share the below information to us for sort out the cause of the issue and provide you a response as early as possible.

1. Are you using any ej.DataManager inside the selectRows event in your sample?

2. Are you using any selectRows event in your sample?

3. Please let us know where you have used the dataManager to render the grid in your code before or after the grid initialization.

4. Share your full grid code snippet to us.

5. Share the scenario of the issue.

For your convenience we have created a sample using adaptor in ej.dataManager to render the grid and the same can be downloaded from following link:

Hi Sellappandi,

it is difficult to pass you a complete example, because I am working to develop an internal framework.

Reading your answer, I have omitted "selectRowIndex" and "rowSelected" parameters from grid definition; 

now the grid loading works fine, but when i click on a row, the grid crash with this exception:

Thanks
