GridView 模板列 在后台获取该行某控件的值 例如批量修改

protected void txtFILESAVEFEE_TextChanged(object sender, EventArgs e)
{
TextBox t = (TextBox)sender;
int Index = ((GridViewRow)(t.NamingContainer)).RowIndex;//获得行号
GridViewRow gRow = GridView1.Rows[Index];
TextBox tb = (TextBox)gRow.FindControl("txtFILESAVEFEE");

Response.Write("<script>alert('" + tb.Text.ToString() + "')</script>");
}
}
