how to bind datatable to datagridview in c#

Try this:

    ServersTable.Columns.Clear();
    ServersTable.DataSource = SBind;

If you don't want to clear all the existing columns, you have to set DataPropertyName for each existing column like this:

for (int i = 0; i < ServersTable.ColumnCount; ++i) {
  DTable.Columns.Add(new DataColumn(ServersTable.Columns[i].Name));
  ServersTable.Columns[i].DataPropertyName = ServersTable.Columns[i].Name;
}

Even better:

DataTable DTable = new DataTable();
BindingSource SBind = new BindingSource();
SBind.DataSource = DTable;
DataGridView ServersTable = new DataGridView();

ServersTable.AutoGenerateColumns = false;
ServersTable.DataSource = DTable;

ServersTable.DataSource = SBind;
ServersTable.Refresh();

You're telling the bindable source that it's bound to the DataTable, in-turn you need to tell your DataGridView not to auto-generate columns, so it will only pull the data in for the columns you've manually input into the control... lastly refresh the control to update the databind.

On the DataGridView, set the DataPropertyName of the columns to your column names of your DataTable.
