In a data grid you define the columns you want to show. If the data source, a data table for example, contains a column you don't want to show then don't create a column for it.

~~For example if you're using WPF, have a look at DataGrid.Columns Property (System.Windows.Controls) | Microsoft Docs[^]~~

Looking at the properties you use it seems that you're using Forms DataGrid. If this is true, I would recommend using DataGridView instead since it has replaced DataGrid. Have a look at Differences Between DataGridView and DataGrid Controls - Windows Forms .NET Framework | Microsoft Docs[^]

With DataGridView you would use DataGridView.Columns Property (System.Windows.Forms) | Microsoft Docs[^]

Hi,
1. If you have a boundField in grid view you can use

 <HeaderStyle CssClass="hidden" Width="30%" />
<ItemStyle CssClass="hidden" Width="30%" Wrap="False" />

2.if you want without boundField

void Grid_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
   e.Row.Cells[0].Visible = false;
}

3.if you are using TemplateField

<asp:TemplateField HeaderText="Customer Name" Visible="false">
    <ItemTemplate>
        <asp:Label Text='<%# Eval("CustomerName") %>' runat="server" ID="LblCusomerName" />
    </ItemTemplate>
</asp:TemplateField>

I hope this will help you.
