Dear friends,

Take a look at the following code:

                    webappteste.WebReferenceX.Service1 sd = new webappteste.WebReferenceX.Service1();         
            DataSet ds = new DataSet();         
            ds = sd.getClientes(); //Get full list of customers from a web service        
            DataTable dt = new DataTable("clientes");         
            dt = ds.Tables[0];         
            RadGrid1.DataSource = dt;         
            int asd = dt.Columns.Count; //Returns 58 columns - CORRECT        
            string tableName = ds.Tables[0].Columns[0].ToString(); //Returns the column name "CLIENTE" - CORRECT        
            int b = ds.Tables[0].Columns.Count; //Returns 58 columns - CORRECT        
            int a = RadGrid1.Columns.Count; //Return 0 columns - WRONG - Why not 58 columns???        

Can you tell me why this is happening?

Is there any other way to load a DataSet into a RadGrid?

Thanks in advance!!

WebService:

[WebMethod]
                    public DataSet getClientes()         
            {         
              SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT * FROM CLIENTES ORDER BY    NOME",connections.retConn())         
              DataSet dataSet = new DataSet();         
              dataAdapter.Fill(dataSet);         
              return dataSet         
            }

You haven't bound the data yet. This should help:

    
            webappteste.WebReferenceX.Service1 sd = new webappteste.WebReferenceX.Service1();  
        
            DataSet ds = new DataSet();  
        
            ds = sd.getClientes(); //Get full list of customers from a web service 
        
            DataTable dt = new DataTable("clientes");  
        
            dt = ds.Tables[0];  
        
            RadGrid1.DataSource = dt;  
        
            RadGrid1.DataBind(); 
        
            int asd = dt.Columns.Count; //Returns 58 columns - CORRECT 
        
            string tableName = ds.Tables[0].Columns[0].ToString(); //Returns the column name "CLIENTE" - CORRECT 
        
            int b = ds.Tables[0].Columns.Count; //Returns 58 columns - CORRECT 
        
            int a = RadGrid1.Columns.Count; //Return 0 columns - WRONG - Why not 58 columns???

Problem solved!

As basic as i needed to define the RadGrid first, like so:

                     private void createGrid()         
             {         
                    RadGrid1.Width = Unit.Pixel(900);         
                    RadGrid1.HorizontalAlign = HorizontalAlign.Center;         
                    RadGrid1.PageSize = 5;         
                    RadGrid1.AllowPaging = true;         
                    RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;         
                    RadGrid1.AutoGenerateColumns = false;         
                     
                    RadGrid1.MasterTableView.PageSize = 15;         
                    RadGrid1.MasterTableView.Width = Unit.Pixel(900);         
                    RadGrid1.MasterTableView.DataKeyNames = new string[] { "CLIENTE" };         
                    GridBoundColumn boundColumn = new GridBoundColumn();         
                    boundColumn.DataField = "CLIENTE";         
                    boundColumn.HeaderText = "Id. Cliente";         
                    boundColumn.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;         
                    boundColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Left;         
                    RadGrid1.MasterTableView.Columns.Add(boundColumn);         
                    boundColumn = new GridBoundColumn();         
                    boundColumn.DataField = "NOME";         
                    boundColumn.HeaderText = "Nome";         
                    boundColumn.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;         
                    boundColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Left;         
                    RadGrid1.MasterTableView.Columns.Add(boundColumn);         
                }         

Another thing ... i am using google chrome to browse, and the grid is not centered ... why?

Take a look at the code:

            </body>         
            </html>         

Once again, thanks in advance. :)
