Hi,

We can't say anything concrete without the code to reproduce.

Please post a simplified test project to reproduce the exception. Please do not attach any assemblies.

Hi,

Please post a simplified test project to reproduce the exception. Please do not attach any assemblies.

Following demo

[Daniil]

Please replace

return new GridPanel();

with

return grid;

[majunior]

Please replace

return new GridPanel();

with

return grid;

Ok, but why in the example in the attached grid returns no rows with values?

[Daniil]

You should change either the type of Reader - JsonReader or ArrayReader, or data that you bind with Store.

So, you could replace

JsonReader jReador = new JsonReader();

with

ArrayReader jReador = new ArrayReader();

Also, there is two Fields with the same DataIndex.

jReador.Fields.Add("MN_USUARIO", RecordFieldType.String);

I guess one of them should be

jReador.Fields.Add("IN_TP_USUARIO"", RecordFieldType.String);
