1.9 动态选中某一行：
AspxgridView1.Selection.SetSelection(i.true)
遍历所有行：
声明变量：DataRowView dv
For(int i=0;i< AspxgridView1.VisbleRowCount;i++)
{
选中行提取数据：
if(AspxgridView1.Selection.IsRowSelected(i))
{
行数据集
dv=（DataRowView）AspxgridView1.GetRow(i);
}
}
二、ASPxGridView样式 & 格式

<AlternatingRow Enabled="true"/> : 交错行效果
<CommandColumn Paddings-Padding="1" /> :
</Styles>
列样式
<dxwgv:GridViewDataTextColumn FieldName="Total" UnboundType="Decimal">
<FooterCellStyle ForeColor="Brown"/>
</dxwgv:GridViewDataTextColumn>
数字日期格式
金额
<dxwgv:GridViewDataTextColumn FieldName="UnitPrice" >
<PropertiesTextEdit DisplayFormatString="c" />
</dxwgv:GridViewDataTextColumn>
时间
<dxwgv:GridViewDataDateColumn Caption="Time" FieldName="Time">

label.Text = string.Format("{0:p}", change);
// 设置模板列image控件的图像
System.Web.UI.WebControls.Image img = (System.Web.UI.WebControls.Image)grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changeImage");
img.Visible = false;
if(change != 0) {
