winform下DataGrid显示样式的小问题
1.   如何让页眉内容居中显示   
 2.   如何让页眉内容显示自己取的名字   
 3.   如何让数据项内容居中显示   
 4.   如何让数据项内容只读   
 5.   怎么去掉DataGird左边的那一个空列?(就是上面有个箭头和一个*号的那一列)   
 一有答案马上结帖
------解决方案--------------------你说的 "页眉 "我理解为 "列名 "不知对不对? 
 假定已存在一个数据源为DataTable的DataGird对象grdText 
 如何让列名显示为自己取的名字: 
 DataTable dt =(DataTable)grdText.DataSource; 
 dt.Columns[0].ColumnName= "自定义列名1 "; //第一列列名 
 dt.Columns[1].ColumnName= "自定义列名1 "; //第二列列名 
 dt.Columns[2].ColumnName= "自定义列名1 "; //第三列列名 
 ……… 
 如何让数据项内容只读: 
 grdText.ReadOnly=true;   
 如何去掉DataGird左边的那一个空列: 
 grdText.RowHeadersVisible =false;   
 至于内容的居中显示,没有使用过,Sorry! 
 抛砖引玉吧!
