gridview中的标题列 [英] header column in gridview

问题描述

我的朋友

i在gridview中显示数据

  string  sql =   select * +   from table_name其中t.months ='2014/05' 
 +   order by 1 DESC; 
 
 OracleCommand command =  new  OracleCommand（sql，conn）; 
 command.CommandType = CommandType.Text; 
 OracleDataAdapter adapter =  new  OracleDataAdapter（command）; 
 
 DataSet dataset =  new  DataSet（）; 
 adapter =  new  OracleDataAdapter（command）; 
 adapter.Fill（dataset）; 
 
 command.ExecuteNonQuery（）; 
 GridView1.DataSource = dataset.Tables [ 0 ]; 
 GridView1.DataBind（）; 
 

当我写

 GridView1.Columns [ 1 ] .HeaderText =   mytext; 

显示错误：



指数超出范围。必须是非负数且小于集合的大小。\\\\ n参数名称：index



任何人都可以帮我PLZ





谢谢

解决方案

确保您的列索引从0开始列，你应该在你的总列范围之间输入列索引

试试这个



GridView1.HeaderRow .Cells [I]。文本= ABC;

解决方案

Make sure your column index starting from "0" while giving into the columns, and you should enter the column index in between the range of your total columns

try this

GridView1.HeaderRow.Cells[i].Text="ABC";
