如何得到gridview中模板列的控件

[jianghanfei]

ScriptManager.RegisterClientScriptBlock(this.GridView1.Rows[].FindControl("LinkButton1"), typeof(GridView), "ERROR2", "alert('对不起，这个类别下还有商品存在，你不能删除!')", true);
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{

int id = Convert.ToInt32(e.CommandArgument);
IList<Commodity> comodities = CommodityManager.GetCommoditiesByJewelryTypeId(id);
if (comodities == null || comodities.Count == 0)
{
JewelryTypeManager.DeleteJewelryTypeById(id);
}
else
{
Response.Write("alert('对不起，这个类别下还有商品存在，你不能删除!')");
//ScriptManager.RegisterClientScriptBlock(this.GridView1.Rows[].FindControl("LinkButton1"), typeof(GridView), "ERROR2", "alert('对不起，这个类别下还有商品存在，你不能删除!')", true);
}
}
}
Rows[]中的行号怎么得到？

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
GridViewRow row = ((LinkButton)e.CommandSource).Parent.Parent as GridViewRow;//获得双击的那一行，这是关键部分
int id = Convert.ToInt32(e.CommandArgument);
IList<Commodity> comodities = CommodityManager.GetCommoditiesByJewelryTypeId(id);
if (comodities == null || comodities.Count == 0)
{
JewelryTypeManager.DeleteJewelryTypeById(id);
}
else
{
Response.Write("alert('对不起，这个类别下还有商品存在，你不能删除!')");
//ScriptManager.RegisterClientScriptBlock(row.FindControl("LinkButton1"), typeof(GridView), "ERROR2", "alert('对不起，这个类别下还有商品存在，你不能删除!')", true);
}
}
}

int index=Convert.ToInt32(e.CommandArgument);
GridViewRow row =GridView1.Rows[index];
string str = gv.DataKeys[index].Value.ToString();

[Rock870210]

CommandArgument='<%# ((GridViewRow)Container).RowIndex %>'
e.CommandArgument获取的就是index

[jianghanfei]

e.CommandArgument获取的是我绑定的Id
