C1TrueDBGrid 怎么不让他自动带出不显示的列？绑定了列，未什么不显示数据？绑定的是datatable，没显示预先设定的列，而是直接显示的是datatable的列。

绑定是使用
c1TrueDBGrid1.SetDataBinding(ds, "AAA", true);
HoldFileds 设置为 true

您也可以通过下面的方式添加非绑定列

C1.Win.C1TrueDBGrid.C1DataColumn Col = new C1.Win.C1TrueDBGrid.C1DataColumn();
C1.Win.C1TrueDBGrid.C1DisplayColumn dc;
c1TrueDBGrid1.Columns.Insert(0, Col);
Col.Caption = "Unbound";
dc = c1TrueDBGrid1.Splits[0].DisplayColumns["Unbound"];
// Move the newly added column to leftmost position in the grid.
c1TrueDBGrid1.Splits[0].DisplayColumns.RemoveAt(c1TrueDBGrid1.Splits[0].DisplayColumns.IndexOf(dc));
c1TrueDBGrid1.Splits[0].DisplayColumns.Insert(0, dc);
dc.Visible = true;

Grid_01 是C1TrueDBGrid；
Grid_01.SetDataBinding(DtData, "ExeBillNo", true);
这样前段一条数据也没有了。

您再对比下代码，如果还不行，将您的demo发上来

DataTable dt = new DataTable();
dt.Clear();
dt.Columns.Add("Name");
dt.Columns.Add("Marks");
DataRow _ravi = dt.NewRow();
_ravi["Name"] = "ravi";
_ravi["Marks"] = "500";
dt.Rows.Add(_ravi);
_ravi = dt.NewRow();
_ravi["Name"] = "ravi2";
_ravi["Marks"] = "5002";
dt.Rows.Add(_ravi);
_ravi = dt.NewRow();
_ravi["Name"] = "rav3i";
_ravi["Marks"] = "5003";
dt.Rows.Add(_ravi);
// c1TrueDBGrid1.DataSource = dt;
dt.TableName = "AAA";
var ds = new DataSet();
ds.Tables.Add(dt);
c1TrueDBGrid1.SetDataBinding(ds, "AAA", true);
C1.Win.C1TrueDBGrid.C1DataColumn Col = new C1.Win.C1TrueDBGrid.C1DataColumn();
C1.Win.C1TrueDBGrid.C1DisplayColumn dc;
c1TrueDBGrid1.Columns.Insert(0, Col);
Col.Caption = "Unbound";
dc = c1TrueDBGrid1.Splits[0].DisplayColumns["Unbound"];
// Move the newly added column to leftmost position in the grid.
//c1TrueDBGrid1.Splits[0].DisplayColumns.RemoveAt(c1TrueDBGrid1.Splits[0].DisplayColumns.IndexOf(dc));
//c1TrueDBGrid1.Splits[0].DisplayColumns.Insert(0, dc);
dc.Visible = true;
c1TrueDBGrid1.Rebind(true);
