private void GenerateColumns()
{

BoundColumn bcID;
BoundColumn bcOrderType;
BoundColumn bcOrderCat;
BoundColumn bcOrderNo;

//ID
bcID = new BoundColumn();
bcID.DataField = "ID";
bcID.ReadOnly = true;
bcID.HeaderText = "ID";
bcID.SortExpression = "ID";
this.dg.Columns.Add(bcID);
//Order Type
bcOrderType = new BoundColumn();
bcOrderType.DataField = "OrderType";
bcOrderType.HeaderText = "Order Type";
this.dg.Columns.Add(bcOrderType);
//Order Category
bcOrderCat = new BoundColumn();
bcOrderCat.DataField = "OrderCat";
bcOrderCat.HeaderText = "Order Category";
this.dg.Columns.Add(bcOrderCat);

//Order No
bcOrderNo = new BoundColumn();
bcOrderNo.DataField = "OrderNo";
bcOrderNo.HeaderText = "Order No";
this.dg.Columns.Add(bcOrderNo);
}

在Page_Load或OnInit中调后dg(DataGrid)正常,但分页后第二页时dg就不显视了.
如果在BindingControls(邦定控件的方法)中调用上面的GenerateColumns效果一样.

为dg.Columns集合增加了列,是要每在邦定一次都要增加一次吗?增加后第二页为何不显?

要重新邦定

[huyaoguo]

在DATAGRID中的页面改变事件中定义POSITION，再绑定。

数据重新邦定当然做了.列集合重新增加也做了:
private void BindingDg()
{
this.GenerateColumns();

int count = (new DataAccess()).... this.dg.VirtualItemCount = count;

DataSet ds = (new DataAccess())....

this.dg.DataSource = ds;
this.dg.DataBind();

//Record Count
this.lblRecordCount.Text = count.ToString();
}

private void dg_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
this.dg.CurrentPageIndex = e.NewPageIndex;
this.BindingDg();
}

[oldhunter]

private void dg_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
this.dg.CurrentPageIndex = e.NewPageIndex;
this.BindingDg();
}


这样没错啊
