GridView与DataGrid无数据时的情况
以下是GridView的方法:

ds.Tables[0].Rows.Add(ds.Tables[0].NewRow()); 

this.dgUserList.DataSource=ds; 

this.dgUserList.DataBind(); 

int columnCount = dgUserList.Rows[0].Cells.Count; 

dgUserList.Rows[0].Cells.Clear(); 

dgUserList.Rows[0].Cells.Add(new TableCell()); 

dgUserList.Rows[0].Cells[0].ColumnSpan = columnCount; 

dgUserList.Rows[0].Cells[0].Text = "没有相关数据资料！"; 

dgUserList.RowStyle.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Center;

以下是DataGrid的方法:

dt.Rows.Add(dt.NewRow()); 

this.dgUserList.DataSource=dt; 

this.dgUserList.DataBind(); 

int columnCount = dgUserList.Items[0].Cells.Count; 

dgUserList.Items[0].Cells.Clear(); 

dgUserList.Items[0].Cells.Add(new TableCell()); 

dgUserList.Items[0].Cells[0].ColumnSpan = columnCount; 

dgUserList.Items[0].Cells[0].Text = "&nbsp;没有相关数据为您显示！"; 

dgUserList.Items[0].HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Left;
