1.取得控件值

using System.Collections.Generic;

//取得当前控件值的集合 直接寻找控件的ID

List<object> keyValues = this.GridViewmethod.GetSelectedFieldValues("F_XXX");//控件的ID

foreach (object key in keyValues)//循环遍历出来

{

}

2.在AspGridView取得某一行

List<object> keyValues = this.GridViewmethod.GetCurrentPageRowValues("F_xxxxx");//F_xxxxx是主键的值

foreach (object key in keyValues)//循环遍历这一行的每一列的数据

{

}

3获得某行某列的值

this.ASPxGridView1.GetRowValues(e.VisibleIndex, new string[] {"列的名字"});

---------------------------------------------------------我是分割线--------------------------------------------------------------------------

1、获取所有选择行中的数据
protected void btnDel_Click(object sender, EventArgs e)
{
//遍历所有可见行
for (int i = 0; i < ASPxGridView1.VisibleRowCount; i++)
{
DataRowView dv;
if (ASPxGridView1.Selection.IsRowSelected(i))
{
//行数据集
dv = (DataRowView)ASPxGridView1.GetRow(i);

//获取选择行的第n列数据
string ordno =dv.Row[0].ToString();
Response.Write("<script>alert('"+ordno+"');</script>");
}
}
}

2、遍历主键列中的所有数据
List<object> keyValue = AspxGridView1.GetSelectedFieldValues("kid");
string str;

foreach(object key in keyValue)
{
str = key.ToString();
}

3、全选/反选
<dxwgv:GridViewCommandColumn ShowSelectCheckbox="True" VisibleIndex="0" Width="50px">
<HeaderTemplate>
<input type="checkbox" οnclick="ASPxGridView1.SelectAllRowsOnPage(this.checked);" />全选
</HeaderTemplate>                                
</dxwgv:GridViewCommandColumn>
常用方法：
获取单元格的值 decimal change = (decimal)grid.GetRowValues(e.VisibleIndex, "Change");
获取模板中的控件 Label label = grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changePercent") as Label;
