assembly "DevExpress.Web.v11.1 - Version=11.1.8.0"
Problem: 'grdPopLC' go to CustomCallback, return with 4 rows but ASPxGridview show nothing

this call my ASPxPopupControl and populate controls inside him

JavaScript
function btnLancDescritivoConceito_click(ID_A){  
    popLancDescritivoConceito.Show();  
    setTimeout(function(){cbpPopLDC_head.PerformCallback(ID_A);},300);  
    setTimeout(function(){cbpDsAvaliacaoDescritiva.PerformCallback(ID_A+';Carregar');},400);  
    setTimeout(function(){grdPopLC.PerformCallback(ID_A + ';Carregar'); }, 500);  
}

this is my ASPxPopupControl

XAML

The ASPxGridView 'CustomCallback' final

C#
var anonLst = from DataRow eRow in Tabela.Rows  
                    where eRow["ID_A"] != DBNull.Value &&  
                              Convert.ToInt32(eRow["ID_A"]) == idAV  
                    select new{  
                                      idFAPV = eRow["ID_B"] != DBNull.Value  
                                                    ? Convert.ToInt32(eRow["ID_B"])  
                                                    : 0,  
                                      dsFAP = eRow["DS_B"] != DBNull.Value  
                                                   ? eRow["DS_B"].ToString()  
                                                   : string.Empty,  
                                      idFACV = eRow["ID_C"] != DBNull.Value  
                                                    ? Convert.ToInt32(eRow["ID_C"])  
                                                    : 0  
                                   };  

DataTable repositorio;  
repositorio = new DataTable("Table_name");  
repositorio.Columns.Add(new DataColumn("ID_B", typeof(int)));  
repositorio.Columns.Add(new DataColumn("DS_B", typeof(string)));  
repositorio.Columns.Add(new DataColumn("ID_C", typeof(int)));  

foreach (var item in anonLst)  
{  
       repositorio.Rows.Add(item.idFAPV,  
                            item.dsFAP,  
                            item.idFACV);  
}  

repositorio.AcceptChanges();  
grdPopLC.DataSource = repositorio;  
grdPopLC.DataBind();

At 'grdPopLC.DataSource = repositorio;', repositorio has data, 4 rows, but on client nothing appear

Hi,
It looks like your data-binding logic is not correct. You need to rebind the grid to data on every page request (e.g., see ASPxGridView - How to bind to multiple data sources). Please examine the Why might paging (sorting, grouping, filtering) not work in the ASPxGridView? KB article to learn more.
The grid should be bound to data on every page request regardless of the technique that is used to prepare data for the grid. Hence, bind the grid to data unconditionally in the Page_Init or Page_Load event handler. If this does not help you, please provide us with a compilable project so that we can compile and debug it locally. This should help us narrow down the problem faster. Thank you for your time and cooperation in advance.
