Visual Studio C#: DataGridView not showing integer

Question

Server: MS SQL. There is a field Value, which is supposed to be integer.

Attached screenshot: why it does not show integer?

Thanks.

AdapterTD = new OdbcDataAdapter("SELECT * from TableName" ORDER BY CAST(Case_number AS Int)", GlobalVariables.ConnectionString);  
  
                dSetTD = new DataSet();  
                AdapterTD.Fill(dSetTD);  
  
                dgvTD.DataSource = dSetTD.Tables[0];

@VAer-4038 , you could try the CellFormatting event to show integer in your datagridview.

 public Form1()  
        {  
            InitializeComponent();  
            dataGridView1.CellFormatting += DataGridView1_CellFormatting;  
        }  
  
        private void DataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)  
        {  
            if (e.ColumnIndex == 3 && e.RowIndex != this.dataGridView1.NewRowIndex)  
            {  
                double d = double.Parse(e.Value.ToString());  
                e.Value = d.ToString("N0");  
  
            }  
        }  

Result in database and in datagirdview:

Maybe an SqlDataAdapter will work differently.

If the columns are not autogenerated, check the definition of this column in Form Designer. You can also change the DefaultCellStyle, setting Format to "N0".
