本文实例讲述了Winform中GridView分组排序功能实现方法。分享给大家供大家参考。具体实现方法如下:
一、问题:
由于客户最近要扩充公司的业务,之前基于Winform+web开发混合式的系统已经不能满足他们的需求,需要从新对系统进行分区处理。
考虑到系统模块里面用到的GridView视图比较多,我就结合了DevExpress第三方GridControl简单的写了个Demo,对数据进行分组排序。
二、实现方法:
主程序源码:

public static DataTable GetTable(string strSQL)
{
return GetTable(strSQL, null);
}
public static DataTable GetTable(string strSQL, SqlParameter[] pas)

}
/// <summary>

/// <param name="pas">参数数组</param>
/// <param name="cmdtype">Command类型</param>
/// <returns>DataTable对象</returns>
public static DataTable GetTable(string strSQL, SqlParameter[] pas, CommandType cmdtype)
{
DataTable dt = new DataTable(); ;
using (SqlConnection conn = new SqlConnection(strConn))
{
SqlDataAdapter da = new SqlDataAdapter(strSQL, conn);
da.SelectCommand.CommandType = cmdtype;
if (pas != null)
{
da.SelectCommand.Parameters.AddRange(pas);
}
da.Fill(dt);
}
return dt;
}
